This information will help you identify some of the common species of sharks. There are 440 different species of sharks in the world today classified into eight different orders described below with some examples of known sharks species for each group. Some of the most popular species of sharks are: One of the most unusual types of sharks our there are know as angel sharks. Many people mistake them for some other types of sea creature. It isnât uncommon for them to be thought of as large stingrays. But the simplest way to tell them apart is by looking at the location of the fins.

Lately, GPS systems have brought a new way to track migration and how long do sharks live, providing more accurate information about them. Shark lifespan vary by kind and it is very different for each of them. While many types live 20 to 30 years in the wild, there are some types that live much longer than others.ately, GPS systems have brought a new way to track migration and how long do sharks live, providing more accurate information about them. Shark lifespan vary by kind and it is very different for each of them. While many types live 20 to 30 years in the wild, there are some types that live much longer than others.

The anal fin is located between the pelvic and caudal fins on the bottom, or ventral, part of the shark. Caudal Fins When it comes to the shark having the ability to propel itself through the water, they utilize what is called the caudal fin. This fin, also known as the tail fin, has an upper and lower lobe that, depending on the type of shark, can vary in shape and size. The upper lobe of the caudal fin produces the majority of the sharkâs thrusting abilities. The tail fin is one of the most important parts of the entire shark anatomy. Types Of Shark Tail Fins Because of all of these different types of fins, sharks are able to maneuver swiftly through the water while also remaining stabilized.

There are a wide variety of shark teeth, just as there are a wide variety of sharks. These teeth can be divided into two general categories. Many shark species, such as the goblin shark and sand tiger, have very long, thin teeth.This structure is well suited for catching small fish. The shark kills the fish immediately, by piercing it with a single bite. Then it swallows the fish whole.Sharks that go after larger prey need a different strategy and a different sort of tooth. They tear into their prey several times, biting off large pieces of flesh. Sharks in this group, which includes the infamous great white shark, have wide serrated teeth.any shark species, such as the goblin shark and sand tiger, have very long, thin teeth. This structure is well suited for catching small fish. The shark kills the fish immediately, by piercing it with a single bite. Then it swallows the fish whole.

The Six gill Shark which is also known as Cow Shark is among the largest sharks of the world. It is predator and feeds on different type of animals. This large shark is found in almost all Oceans, especially in Pacific Ocean. It can be as long as 18 ft. This predator shark rarely attacks on human. Average weight is 590 kg of this type of shark.

The typical life expectancy in the wild for Hammerhead Sharks is from 20 to 30 years approximately. Whale sharks (Rhincodon typus) are also believed to live above 100 years, suggesting that the time to reach maturity is longer and young will take longer to born, making this type of shark more vulnerable.ately, GPS systems have brought a new way to track migration and how long do sharks live, providing more accurate information about them. Shark lifespan vary by kind and it is very different for each of them. While many types live 20 to 30 years in the wild, there are some types that live much longer than others.

The most common sharks seen around Hawaii are Blacktip Sharks, Reef Blacktip Sharks, Reef Whitetip Sharks, Tiger Sharks, Sandbar Sharks, Galapagos Sharks, Scalloped Hammerhead Sharks, and Gray Reef Sharks.

Shark teeth are the most common type of fossil for a number of reasons. First, shark teeth, like most teeth, are made of dentin, a hard calcified tissue that does not easily decompose. Dentin is harder and denser than bone.In a tooth, the Dentin is surrounded by a very hard enamel shell.Secondly, to maintain a sharp smile, shark teeth are designed to regularly fall out and be replaced.dditionally, shark teeth can look different between male and female sharks of the same species, from juveniles to adults of the same species, and finally they look different if they are in the upper jaw vs. lower jaw.

The world's biggest school of sharks was observed in Galapagos, it was a single school of 1100 Hammerhead Sharks. The world's smallest shark is a small type of the Cat Shark. The shark is just 6 inches, when it is fully grown. The Thresher Shark can jump 20 feet out of the water.he world's most dangerous shark is the Bull Shark. The world's biggest shark is the Whale Shark (a shark is a fish). The Whale Shark can be up to 53 feet long and weight more than 13 ton.

In the wild, it is believed that their life expectancy is about 30 years. Sandbar sharks or Brown sharks are thought to live between 20 and 30 years. Investigation made by Joung (2004) found to be about 20 years of age. While, Sminkey (1996) mention that sandbar sharks can live to be more than 30 years old.ately, GPS systems have brought a new way to track migration and how long do sharks live, providing more accurate information about them.

These young sharks may take several months to hatch. In certain species of sharks, the eggs stay inside the female shark for a period of time before they are laid, this allows the sharks to develop fully and spend less time in the immobile egg cases before they hatch. Types Of Sharks That Lay Eggs. Just a few species of sharks that lay eggs include: Bamboo sharks or carpet sharks. Swell sharks. Cat sharks. Horn (bullhead) sharks.

Thanks for visiting this Wonder of the DayÂ® about sharks, Madison! There are many, many different types of sharks, including Great Whites, in the oceans of the world. Because there are so many different sharks in so many different bodies of water, it would be impossible to count them all.

Shark tooth. A shark tooth is one of the numerous teeth of a shark. A shark tooth contains resistant calcium phosphate materials. Sharks continually shed their teeth; some Carcharhiniformes shed approximately 35,000 teeth in a lifetime, replacing those that fall out. There are four basic types of shark teeth: dense flattened, needle-like, pointed lower with triangular upper, and non-functional. The type of tooth that a shark has depends on its diet and feeding habits. In some formations, shark's teeth are a

Hammerhead Shark. There are eight different species of Hammerhead shark.

Although both animals live and thrive in the ocean and there is a species of shark that is called the whale shark the whale species is very different from sharks. In fact sharks are actually considered a type of fish while whales, dolphins and porpoises are marine mammals.nother major difference between whales and sharks is how the two species give birth. Whales give birth the same way that humans and other mammals do (through a pregnancy period or gestation term) while sharks and fish lay eggs.

Many shark species, such as the goblin shark and sand tiger, have very long, thin teeth. This structure is well suited for catching small fish.

The skin of a shark is made of tiny denticles, which are made of the same enamel that teeth have, meaning they too can fossilize. Some more primitive sharks have spines in their fins that will fossilize. Finally, shark feces, or coprolites, are sometimes found preserved.dditionally, shark teeth can look different between male and female sharks of the same species, from juveniles to adults of the same species, and finally they look different if they are in the upper jaw vs. lower jaw.

The Great White Shark averages an impressive 6.6 to 7 metres (21.6 to 23 feet) and the grizzly Ragged Tooth Shark comes in at about 3.6 metres, or just under 12 feet. With these mammoth hunters gliding through the waters, it is no wonder that sharks have earned themselves a fearsome reputation. Different shark species tend to prefer different waters (in terms of the prey found therein and the temperatures of the ocean) but, generally, sharks are found all over the world.

Tropical sharks include the huge filter-feeding whale shark, the great hammerhead shark, the nurse shark, the tiger shark, and the bull shark, which is found in both the ocean and in fresh water lakes in the tropics.Certain large species, such as the whale shark, range throughout the tropical region all over the world.ropical sharks include the huge filter-feeding whale shark, the great hammerhead shark, the nurse shark, the tiger shark, and the bull shark, which is found in both the ocean and in fresh water lakes in the tropics.

The most noticeable features on the Porbeagle Shark is a white spot or blotch at the base of the first dorsal fin. By the way, to learn more about the different types of fins sharks can have, visit the Shark Anatomy page. The Porbeagle preys mainly on cephalopods and small bony fish.ou can mostly find this shark in the North Atlantic on the coasts of Greenland, Canada, Russia and Scandinavia. Further south, this shark can be spotted near Bermuda, New Jersey, Madeira, Brazil, Chile and Morocco. It has also been sighted in the Mediterranean Sea. The Porbeagle is known to migrate long distances.

The Swai Fish, or Iridescent Shark, is a rather unremarkable fish that is typically farmed in Asia. However, it seems to create a bit of controversy in what contexts it appears. Whether it is to be kept in an aquarium or to be eaten at the dinner table, the Swai Fish has opposing viewpoints. The Iridescent Shark is not really a shark but gets its name because it resembles on in appearance. It can be found on the market as Swai Fish and shark catfish. It is a member of the catfish family.

The smallest shark is the Spined Pygmy shark, which, when fully-grown, is only 7-8 inches (18-20 cm) long. Most sharks are intermediate in size, about the same size as people, 5-7 feet (1.5-2.1 m) long. Half of the 350 shark species are under 39 inches (1 m) long.

The most dangerous sharks are the Great White shark, the Tiger shark, the Hammerhead shark, the Mako shark and the Bull shark. On average, there are only about 100 shark attacks each year and only 10 of those result in a human death. You should check it out from their perspective, though! People kill thousands of sharks in a year for sport and for food. Shark skins are used to make products like any other leather would be. Up until the 1950's, shark livers were used as a vitamin A supplement. Shark fin soup and shark steaks are both eaten in many countries (Mako, seen in the top photo, is the most popular in the United States).

SHARK CARTILAGE Overview Information. Shark cartilage (tough elastic tissue that provides support, much as bone does) used for medicine comes primarily from sharks caught in the Pacific Ocean. Several types of extracts are made from shark cartilage including squalamine lactate, AE-941, and U-995.Shark cartilage is most famously used for cancer, including a type of cancer called Kaposiâs sarcoma, that is more common in people with HIV infection.ikely Ineffective for: 1  Cancer. 2  Most research shows that taking shark cartilage by mouth does not benefit people with advanced, previously treated cancers of the breast, colon, lung, prostate, and brain or advanced, previously treated non-Hodgkin's lymphoma.

Shark diet also adapts to survive. Some shark species may prefer certain types of prey, but when they are scarce, they adjust their eating habits to whatever is available. Sharks arenât picky with their food sources. Some sharks have been known to eat items including coal, oil, trash, and clothing that finds its way into the water. Sharks classification split into two groups according to their diet: CARNIVOROUS SHARKS. A carnivorous shark diet usually includes fish, mollusks, and crustaceans. Large species also consume marine mammals such as seals, dolphins, sea lions, and porpoises, as well as large fish species such as tuna, mackerel, and even smaller shark species. Some even extend their consumption to seabirds.

Sharks have five different kinds of fins. 1  Paired pectoral fins lift the shark as it swims. 2  Paired pelvic fins stabilize the shark. 3  One or two dorsal fins also stabilize the shark.  Not all sharks have an anal fin, but 1  it. The caudal or tail fin moves the shark forward.

Hammerhead sharks are commonly seen in larger groups during the summer months when the hammerhead sharks are migrating together in search of cooler waters. The great hammerhead shark is the largest species of hammerhead shark and one of the few species of hammerhead shark that is potentially dangerous to humans.This is due to the sheer size of the giant hammerhead shark and also because the giant hammerhead is known to have an aggressive temperament.ammerhead sharks are commonly seen in larger groups during the summer months when the hammerhead sharks are migrating together in search of cooler waters.

The Tiger Shark is a type of shark encountered in Stranded Deep. They can be found living in shallow ocean biomes such as the Islands, Sand Plains and Shallows. Tiger sharks can be identified by their dull gray coloration, along with their distinctive stripes that run down the length of their body. A tiger shark can be killed with exactly 10 hits from an axe. 2  As of v0.03.H2, the spawn chance of a tiger shark has been adjusted from 100% down to 30%. 3  There is a bug currently located in the game: once a tiger shark latches onto the player, it will drag the player back to the island.

For Hammerhead sharks, their life expectancy ranges from 20 to 30 years. Brown sharks and sandbar sharks are thought to live between 25 to 30 years. A research conducted in 2004 by joung identified that the lifespan of brown sharks is about 25 years while sandbar sharks can live up to 30 years.heir lifespan vary by kind. Even though most of them live about 20 to 30 years in the wild, there are some types that live longer than others. For instance, the dogfish has one of the longest lifespan of more than 100 years while blue shark has an average lifespan of about 15-16 years in the wild.

The life-span of tiger sharks in the wild is considered to be 27 years in average, even though some may live up to 50 years of age. As with other species, tiger sharks in captivity do not live as extensive as in wildlife reaching only 17 to 20 years. Some experts presume that the lifespan of the Great White Sharks is approximately 30 years (Levine, 1988) but other research indicates that they can reach up to 40 years. The typical life expectancy in the wild for Hammerhead Sharks is from 20 to 30 years approximately. Whale sharks (Rhincodon typus) are also believed to live above 100 years, suggesting that the time to reach maturity is longer and young will take longer to born, making this type of shark more vulnerable.

The truth is that most sharks are carnivorous and efficient predators, although some others feed on plankton. It depends on the type of shark as various species have different feeding habits. Shark feeding also depends on where they live because this is the main factor to define the kind of prey available.

Types of attacks. Shark attack indices use different criteria to determine if an attack was provoked or unprovoked.. When considered from the shark's point of view, attacks on humans who are perceived as a threat to the shark or a competitor to its food source are all provoked attacks.

Mating and Reproduction of Sharks. Habitat Evolution Features Anatomy Senses Reproduction. Our knowledge of the many different types of reproductive strategies of sharks is still limited. This variety is precisely why it is difficult to make a certain generalization on their reproductive methods, although these are what make sharks so successful.

1. Shark. This means any type of meat eating shark such as Longfin Mako, Shortfin Mako, Blacktip, or common Thresher shark. Because sharks are at or near the top of the food chain, they consume other types of fish as their main source of food.

Sometimes; all sharks are predators after all. Most shark species (about 80 percent) have never been known to attack humans. There are four shark species that have always been considered dangerous to humans: great white shark, tiger shark, bull shark and oceanic whitetip shark. 17 other species of sharks have also attacked humans.

The primary shark predators of bottlenose dolphins are the bull shark, tiger shark, dusky shark and great white shark. Shark bite scars on dolphins indicate that sharks typically attempt to ambush dolphins from behind and below. Some researchers think that shark attacks may not even be an attempt to eat a dolphin.

Sand tiger shark. Not to be confused with sand shark, tiger shark, or nurse shark. The sand tiger shark (Carcharias taurus), grey nurse shark, spotted ragged-tooth shark, or blue-nurse sand tiger is a species of shark that inhabits subtropical and temperate waters worldwide.

White sharks, also known as great white sharks, are the #1 shark species that cause unprovoked shark attacks on humans. These sharks are the species made infamous by the movie Jaws. According to the International Shark Attack File, white sharks were responsible for 314 unprovoked shark attacks from 1580-2015. Of these, 80 were fatal.

The shark's nose may work so well because it doesn't have to do anything else. Sharks use their noses just for smelling. Breathing is accomplished with a shark's gills, and the shark's sense of smell is not connected to its mouth in any way. Sharks often don't know how something is going to taste until they've taken a bite. This is how some people are able to escape from a shark attack -- the shark gets a little nibble of a foot and decides to reject the prey. Can sharks hear as well as they smell?

Best Answer: If you are asking which is more dangerous, both sharks and whales has their species that can be potentially dangerous. Even though Great white sharks is the most intimidating of all sharks, they're not the most aggressive sharks.Tiger sharks are way more aggressive than the Great white sharks. shark is more dangerous than a whale because whales eat krill. Sharks eat meat but that doesn't mean they would just swim up and eat you. A shark would only hurt a person if you were in its territory,you were surfing and looked like a seal from below, or if it was desperately hungry.

Whales are much larger than sharks. The blue whale is the largest of all the mammals on Earth. When a whale weighs more than 100 tons, the shark weighs about 2,000 kg. Sharks hunt for their food. Whales do not have this hunting tendency. Plankton and krill are the food of whales.hale vs Shark. Whales are mammals and sharks are fish. When whales give birth to young ones, sharks lay eggs. Unlike the young sharks, young whales are fed milk. The whales raise their young ones whereas sharks do not.

The name bull shark comes from the shark's stocky shape, broad, flat snout, and aggressive, unpredictable behavior. In India, the bull shark may be confused with the Sundarbans or Ganges shark. In Africa, it is also commonly called the Zambezi River shark or just Zambi.he bull shark is a special case in evolutionary history. Some of its closest living relatives do not have the capabilities of osmoregulation. The bull shark's genus, Carcharhinus, is shared by the sand bar shark that is not capable of osmoregulation.

Tiger sharks are some of the largest predators in the ocean and have few species feed on them. Some juvenile tiger sharks, however, fall prey to other sharks.

Sharks and remora fish work together. A not so picky eater the remora fish attaches itself the the shark. These fish also attach to whales, tuna, sea turtles and many other large sea animals. The remora fish attaches to the belly of the shark by a sucker disc in it's mouth. It travels everywhere the shark goes. It eats any parasites on the shark which helps keep the shark clean. It also eats any leftover food from the shark. The remora (sucker fish) gets to eat and the shark stays clean and healthy.

Most species of sharks have five pairs of gill slits on each side of their head, but a few have six or seven pairs. The gills are crucial to a sharks breathing system. By opening its mouth, water is drawn into the shark. The open mouth gives the appearance of a smile in many sharks. When a shark closes its mouth, the water is forced over its gills and the tiny blood vessels in shark gills absorb oxygen from the water. To aid water flowing over its gills most sharks swim forward all the time, called ram ventilation, and is characteristic of more active open ocean sharks.

It is taken from the livers of three species of shark: the deep sea shark (Centrophorus squamosus), the dogfish (Sqaulus acanthias), and the basking shark (Cetorhinus maximus). The liver makes up about 25% of the total shark body weight of these sharks. Shark liver oil is used along with usual cancer drugs to treat leukemia and other cancers; to prevent radiation illness from cancer X-ray therapy; to prevent the common cold, flu, and swine flu; and to boost the bodyâs immune system.

Since then, sharks have diversified into over 500 species. They range in size from the small dwarf lanternshark (Etmopterus perryi), a deep sea species of only 17 centimetres (6.7 in) in length, to the whale shark (Rhincodon typus), the largest fish in the world, which reaches approximately 12 metres (39 ft) in length.hey have several sets of replaceable teeth.

The spiral valve allows the food to be completely absorbed and digested. The more food that can be absorbed, the less a shark has to eat. The liver, an accessory organ to the digestive system, also has a major evolutionary significance in the shark. The lamprey liver is a single small lobe behind the heart.he structure of the digestive tract and its evolution are affected by many factors. Such factors include the type of food eaten, the level of activity and metabolism, and the size of the animal. The mouth and oral cavity of the shark has evolved according to the type of food the shark eats.

They include bony fish, birds, dolphins, small sharks including others of the same species, terrestrial mammals, echinoderms, and crustaceans. They often bump into their prey and then bite it while they are still surprised from that initial bump.

Shark teeth are the most common type of fossil for a number of reasons. First, shark teeth, like most teeth, are made of dentin, a hard calcified tissue that does not easily decompose. Dentin is harder and denser than bone.he skin of a shark is made of tiny denticles, which are made of the same enamel that teeth have, meaning they too can fossilize. Some more primitive sharks have spines in their fins that will fossilize. Finally, shark feces, or coprolites, are sometimes found preserved.

Sharks, as all fish, use their body and tail in a side to side motion to move through the water. Shark fins are rigid not flexible, and are supported by rods made of cartilage. Sharks have five different kinds of fins. Paired pectoral fins lift the shark as it swims.

According to the infographic, sharks killed 12 people last year, but humans kill that many sharks every four seconds, adding up to an estimated total of 100 million sharks annually. Many sharks are killed by 'finning,' a process in which a shark's fins are cut off to be sold for shark fin soup.

It was once believed that all sharks had to swim constantly in order to breathe and could not sleep for more than a few minutes at a time. Oxygen-rich water flows through the gills during movement allowing the shark to breathe. While some species of sharks do need to swim constantly, this is not true for all sharks. Some sharks such as the nurse shark have spiracles that force water across their gills allowing for stationary rest. Sharks do not sleep like humans do, but instead have active and restful periods.

White Shark Diving: White Shark Ventures invites you cage diving with great white sharks in the aptly named Shark Alley , near the fishing village of Gansbaai, South Africa. Sharks are quite possibly the world's most feared animals. From the smallest sand shark to the enormous whale shark, they are sleek, muscled, and some are almost as agile as a dolphin. There is no doubt that they are the most evolved predators in the ocean.

Shark Week The Fastest Shark in the Ocean The shortfin mako shark is the fastest shark in the ocean.

Add to that the fact that sharks, as apex predators, are vital to maintaining the balance of our ocean ecosystems and you begin to understand the true value of sharks. Sharks and Ecotourism Sharks are worth more alive than dead! Divers rate sharks as among their top attractions on a dive site. Because of this, sharks bring millions of dollars in ecotourism revenue to coastal communities that can provide both protection for sharks and offer added sustainable tourism infrastructure.

Size: The spined pygmy shark, a deep-sea shark, is one of the smallest at only about 7-8 inches, while the whale shark is the largest shark, and fish, at about 50 feet in length. Lifespan: Although lifespan varies by shark species, most sharks are long-lived and generally tend to live for 20-30 years. Species like the spiny dogfish and the whale shark are believed to live for over 100 years!

Shark finning. Shark finning refers to the removal of fins from sharks, often while the shark is alive. The sharks are sometimes discarded back to the ocean, still alive but without their fins. Unable to swim effectively, they sink to the bottom of the ocean and die of suffocation or are eaten by other predators. Shark finning at sea enables fishing vessels to increase profitability and increase the number of sharks harvested, as they only have to store and transport the fins, by far the most profitable part o

Tiger sharks are all of the above, according to Dr. Erich K. Ritter. Tiger sharks are noted for having the widest food spectrum of all sharks. They can eat almost anything, from turtles to birds, as well as other sharks and fish.Besides normal prey they even eat garbage like tires, nails or car license plates, as sometimes documented by examinations of their stomach contents.iger sharks are noted for having the widest food spectrum of all sharks. They can eat almost anything, from turtles to birds, as well as other sharks and fish.

Frilled sharks are so unusual that the 2 known species, the Frilled Shark and the Southern African Frilled Shark, are placed by some biologists in their own order (as we do, here). Historically, Frilled sharks have been considered a Family within the order of Hexanchiformes, or Cow sharks.ossil evidence dates frilled sharks to 95 million years ago. Some paleontologists suggest it is a living cladodont shark, a shark that existed as long ago as 380 million years.

The bull shark (Carcharhinus leucas), also known as the Zambezi shark or, unofficially, as Zambi in Africa and Nicaragua shark in Nicaragua, is a requiem shark commonly found worldwide in warm, shallow waters along coasts and in rivers.he bull shark is a special case in evolutionary history. Some of its closest living relatives do not have the capabilities of osmoregulation. The bull shark's genus, Carcharhinus, is shared by the sand bar shark that is not capable of osmoregulation.

The pup (which is what a baby shark is called) will live its life at the top of the ocean's food chain. But before it grows larger, the pup must avoid predators bigger than it isâincluding other great white sharks. Many baby sharks do not survive their first year. Young great white sharks eat fish (including other sharks) and rays. As it grows, the shark's favorite prey becomes sea mammals, especially sea lions and seals. Sharks count on the element of surprise as they hunt.

Answer 3: Typically a shark has two to three working rows of teeth with 20 to 30 teeth in each row, although a whale shark has about 300 teeth in each row. The replacement rate has not been measured in most sharks but normally the teeth seem to be replaced every two weeks. The lemon shark replaces its teeth every 810 days, and the great white shark replaces its teeth about every 100 days for young sharks and about every 230 days for old sharks. (From wikipedia)

15. Shark teeth were recently discovered to contain fluoride. 16. Sharks do not suffer from cavities. 17. The inside of shark and human teeth contains a soft mineral known as dentin. 18. The coating of shark teeth is acid resistant and less water soluble than our teeth. 19. Shark teeth and human teeth are equally as hard. 20. Even though many sharks have sharp teeth that could inflict a wound to humans, sharks should always be treated with respect.

The Ground Sharks are the largest of shark orders with 277 currently identified species which includes many of the most typical, well known sharks as well as some unusual and potentially dangerous ones. Ground Sharks include Bull Sharks, Hammerheads, Blacktip, and Catsharks. While some of the Shark orders show great diversity as well as highly specialized characteristics, Ground Sharks enjoy more commonality within their order. They tend to be generally adapted, able to flourish in a broad array of habitats and enjoy a wide range of prey.

Bull sharks have been found up the Mississippi River as far north as Illinois, and one was found 2,500 miles up the Amazon. Lake Nicaragua is full of bull sharks, known locally as Nicaragua sharks. The Zambezi River in Africa is home to many bull sharks, which are called Zambezi sharks there. After Hurricane Katrina, large numbers of bull sharks were reportedly seen swimming in Lake Pontchartrain. Bull shark moms tend to give birth in coastal lagoons, river mouths, and other estuaries.

However, not everyone is out to get the tiger sharks. Scientists say that predators such as the tiger shark keep the ocean's ecosystem in balance, and in Native Hawaiian belief, tiger sharks are aumakua, or sacred guardian spirits.If you'd like to learn more about tiger sharks, swim over to the links on the next page.ea snakes were found 60 percent of the time, and sea turtles were found in 27 percent of the sharks, although only in larger sharks [source: Heithaus ]. But what gets people's attention is the wackier things that have shown up in a tiger shark's stomach.

For Hammerhead sharks, their life expectancy ranges from 20 to 30 years. Brown sharks and sandbar sharks are thought to live between 25 to 30 years. A research conducted in 2004 by joung identified that the lifespan of brown sharks is about 25 years while sandbar sharks can live up to 30 years.he life expectancy of tiger sharks in the wild is thought to be 28 years in average while some reach up to 50 years. But Just like the other kind, tiger sharks in captivity do not have a longer life span as those in the wild.

Whale sharks are fascinating creatures. The whale shark is one of only three filter-feeding sharks (the other two are the basking and megamouth shark).It is suggested that whale sharks do not reach maturity until they are over 30 years of age and a size of 9 meters.They can live to be over 100 years old.ut there could be whale shark birthing ground on other locations, we just do not know much about the mating and reproductive behaviour of the species. The smallest regularly observed whale sharks are about 2,5 meters in length, and probably around one year old. There is no knowledge where they spend their first year.

Dolphin teeth are more for catching fish than for tearing apart large prey, as sharks' teeth are. And sharks have very tough skins--hard to tear. But dolphins have a hard rostrum--beak--that's perfect for ramming. Sharks can and do kill and eat dolphins, which are highly nutritious for a shark. Dolphins aren't equipped to eat sharks, however, except for Orcas, which while called a whale, are really the largest species of dolphin. For other dolphins, then, they have no reason to kill a shark for food--just for defense--and dolphins have been known to swim off when a shark attacks one member of a pod.

In general, sharks do not eat humans. Despite their scary reputation, sharks rarely ever attack humans and would much rather feed on fish and marine mammals. Only about a dozen of the more than 300 species of sharks have been involved in attacks on humans. Sharks evolved millions of years before humans existed and therefore humans are not part of their normal diets. Sharks are opportunistic feeders, but most sharks primarily feed on smaller fish and invertebrates. Some of the larger shark species prey on seals, sea lions, and other marine mammals.

There is now a warning system when sharks are seen near the coast. We have a shark watch database we are developing on iNaturaist and have developed recommendations to avoid shark encounters. We can, and we must coexist with this important, and increasingly threatened ocean predators. 5) What is Sharktober? We launched Sharktober and Sharktoberfest celebrations in 2008 to celebrate the return of the white sharks to our Sanctuary offshore, and to educate and motivate the public to protect sharks. The first campaign was to drive support for the now successful California Shark Fin Ban introduced by Sea Stewards (now Shark Stewards).

The bull shark, also known as the Zambezi shark in Africa, and Lake Nicaragua shark in Nicaragua, is a requiem shark commonly found worldwide in warm, shallow waters along coasts and in rivers. The bull shark is known for its aggressive nature, predilection for warm shallow water, and presence in brackish and freshwater systems including estuaries and rivers. Bull sharks can thrive in both salt and fresh water and can travel far up rivers. They have been known to travel up the Mississippi River as far as Alton, Illinois, although few freshwater human-shark interactions have been recorded.

The average time span for a female bull shark to be pregnant is around 10 to 11 months. The male bull shark is able to begin reproducing around the age of 15 years while the female cannot begin reproducing until the age of 18 years.

The Bull shark (Carcharhinus leucas), or Zambezi shark, is a species of shark of the genus Carcharhinus. The shark grows to a maximum length of 11.5 feet (3.5 metres), but is usually 7.3-7.8 feet (2.2-2.3 metres) long.It is found in tropical and subtropical coastal waters worldwide, as well as river systems and freshwater lakes.he meat of the Bull shark is eaten by humans, the hide is used for leather, the fins are used in shark-fin soup and the liver is made into vitamin-rich oils. In certain areas, such as the Gulf of Mexico and South Africa, the Bull shark is also a popular game fish.

GIVING BIRTH TO LIVE SHARKS (VIVIPARITY). The female gives birth to live offspring, just like mammals, and they are born fully developed. There is a placental link to the eggs since they feed on the placenta. Specifically, the yolk sac develops within a placenta that is attached to the wall of the uterus and gives the offspring the nutrients necessary for their growth. Examples of viviparous are hammerhead sharks (Sphyrnidae family), the bull shark (Carcharhinus leucas) and the blue shark (Prionace glauca). These species give birth to live sharks which they abandon after the delivery. Newborn sharks instinctively know how to survive alone. Shark mothers do not take care of their young. EGGS DEVELOP INSIDE THE MOTHER (OVOVIVIPARITY)

Because of these characteristics, many experts consider bull sharks to be the most dangerous sharks in the world. Historically, they are joined by their more famous cousins, great whites and tiger sharks, as the three species most likely to attack humans. Bull sharks get their name from their short, blunt snout, as well as their pugnacious disposition and a tendency to head-butt their prey before attacking. They are medium-size sharks, with thick, stout bodies and long pectoral fins. They are gray on top and white below, and the fins have dark tips, particularly on young bull sharks. They are found cruising the shallow, warm waters of all the worldâs oceans. Fast, agile predators, they will eat almost anything they see, including fish, dolphins, and even other sharks.

The outer design of sharks and bony fish is also contrasting. 1  Shark skin is covered by dermal denticles, toothlike placoid scales that are covered with enamel. 2  Shark fins are stiff and lack the fine bony spines and muscle control found in teleost. 3  Both sharks and bony fish have caudal fins, or tail fins with two lobes. The skull of a shark is made of only 10 cartilaginous elements while a bony fish skull has about 63 bones. 2  Bony fish have pleural ribs formed from dermal bone and sharks lack these ribs. 3  Unlike bony fish that have a protective bony plate covering their vulnerable gills, the gill slits of a shark are exposed and visible.

How do sharks see, smell and hear? Never seen a shark with ears? Well, sharks only have an inner ear. Two holes on either side of a shark's head might be the only clue you'd have to the presence of shark ears. Yet sound is often the shark's first tip-off that prey is nearby. The prey doesn't even have to be that close.

Medium Fish and Small Shark Eaters. Some of the sharks who have the above mentioned as their food are the bull and blue sharks. Bull sharks are known to not be so picky with their food. However, they are fond of eating bony fishes such as flounders, stingrays, and even other sharks like the hammerhead shark.

Hawaii is also home to about 40 species of sharks, including the harmless whale shark to the not so harmless tiger shark. Occasionally great white sharks have been seen as well. The most common shark species in Hawaii are the gray reef, white-rip and black-tip reef sharks.

Confidence votes 11. Sharks are attracted to blood and smelly farts. If there is ever a shark attach try not to poop alot because that will attract more sharks because of shark sugar. Most of the time if there is a shark attack a helicopter will come to assist but the helicopter will not attract more sharks to come.

megalodon shark was much bigger than whale shark cause a megalodon shark is almost 100 feet while an whale shark is just 62-75 feet. But the megalodon has been extinct for aboâ¦ut 1.5 million years, leaving the whale shark the biggest shark alive.

The bull shark is known to be a solitary hunter, although brief moments exist in which the bull shark teams up with another bull shark to make hunting and to tricking prey easier. Sharks are known to be opportunistic feeders, and the bull shark is no exception to this, as it is part of the Carcharhinus family of sharks.

But the thought of crossing paths with a shark (there are few white sharks in the Gulf - thank goodness) isn't a thought I enjoy. Tiger sharks, bull sharks, and even black and white tip sharks are no laughing matter in my book, and while shark encounters are rare in Texas, the do happen every year.

Tiger sharks have darker stripe on their sides, especially in younger sharks. These are large sharks that may grow over 18 feet in length and weigh up to 2,000 pounds.

Shark fish is eaten in fish and chips in parts of New Zealand and Australia. In many countries, shark meat is sold under the common name of fish. Sharks are often hunted for their fins.

Stories tell of men with shark jaws on their back who could change between shark and human form. A common theme was that a shark-man would warn beach-goers of sharks in the waters. The beach-goers would laugh and ignore the warnings and get eaten by the shark-man who warned them. Hawaiian mythology also includes many shark gods.

Basking sharks belong to the few plankton eaters in the shark world. The only other filter-feeding species known to prefer plankton are whale sharks (Rhincodon typus, Fact Sheet Shark Info 3/00) and megamouth sharks (Megachasma pelagios, Fact Sheet Shark Info 1/99).

How does the Goblin Shark reproduce? Little is known about the goblin shark's reproductive systems but it is assumed that it reproduces almost identically to most other sharks. Sharks fertilize the egg within the female body which is unique for a bony fish . The male shark has a sex organ called claspers which transfers sperm into the female shark in order to fertilize eggs .

Most shark attacks occur less than 100 feet from the shore. More people are killed by bee stings and lightning than by shark attacks. Worldwide about 30 people die each year from shark attacks, which means a person has a one in 300 million chance of being killed by a shark. A shark attack most often occurs when a shark mistakes a person for a seal or other animal.

The lifespans of large sharks are greater than that of the smaller sharks. Great white shark reaches its maturity at the age of 15 and it has the lifespan of 25 to 30 years.

Shark teeth are also useful in conducting research about the structure of teeth, shark migration patterns, and identifying shark species. The most ancient types of sharks date back to 450 million years ago, during the Late Ordovician period, and are mostly known by their fossilised teeth.

An example of such a shark is the bull shark which is notorious for wandering into freshwater and has been found over 4200 kilometers / 2,600 miles upstream in rivers such as the Amazon. Bull sharks also live in Lake Nicaragua and these sharks are often referred to as true freshwater sharks. Recent studies do however show that even if bull sharks can live for many years in Lake Nicaragua, they do not breed there and they need to return to the ocean to breed.

Most of them live in warm seas but some sharks prefer colder regions like the seas around Antarctica. The first sharks lived in our oceans about 300 million years ago.

A chongo bull is an all out male bull. An aggressive, muscular, roaring to go type of cow. The type of bull that would buck anyone off in a rodeo. bull shark is similar to a bull in the way that it is very aggressive and is one of the most dangerous shark species. What makes this shark so dangerous is that it can toler â¦ ate fresh water and have been found as far north as rivers in New Jersey.

Although you'd be hard-pressed to find a person who adores the visage of any shark, goblin sharks stand out as the ugly ducklings of the family. The scientific name of the species is Mitsukurina owstoni, but its memorable mug earned the goblin shark its common name.

Sandbar shark. The most common shark found in the Chesapeake is the sandbar shark (Carcharhinus plumbeus). The sandbar shark can be found in the Atlantic Ocean from Massachusetts all the way to southern Brazil, and is a seasonal visitor to the Chesapeake Bay in the summer and fall.n fact, there are at least 12 species of sharks found in the Bay. Some are quite abundant, while others are very rare. Whether you need to be concerned about shark attacks while swimming or boating is another story though.

Sharks in the Caribbean: The Facts. Shark attacks in the Caribbean are rare. The chances of being attacked in North America and South Africa are much higher. Florida shark attacks average from 20-30 per year, and the Bahamas has had the most attacks out of all the islands in the Caribbean.iger Sharks: Another large shark, capable of growing to a length of over 16 feet, or 5 meters, the Tiger Shark can be found in the Caribbean and other warm waters around the world.

Hammerhead sharks are large carnivorous fish that prey on large fish and occasionally hammerhead sharks will hunt small water mammals. Hammerhead sharks are found in the warmer waters of oceans worldwide but hammerhead sharks are particularly found in coastal waters, and along continental shelves. The shallow waters that the hammerhead sharks inhabit allow the hammerhead shark to hunt prey more easily.

Fun Facts About Zebra Sharks: 1  The long tail of zebra shark allows it to be more agile in the water. 2  Zebra shark is Black, Brown, Grey in color. 3  As zebra sharks have intense patterns, they are included in the group of carpet sharks, as the patterns on a zebra shark look like the designs of a carpet. They have tail fins on their body that are able to grow as long as their body.

HOW DO SHARKS BREATHE? Beneath the gills are tiny blood vessels that extract oxygen out of the water as it passes over them. Most shark species breathe by swimming with their mouths open which allows the water to pass over the gills. Some sharks like nurse, angel and lemon sharks have strong neck muscles that pump water over the gills, allowing the shark to breathe while resting on the ocean bottom. Sharks are fish, and therefore breathe through the use of

Many scientists agree that since bull sharks often dwell in shallow waters, they may be more dangerous to humans than any other species of shark, and that they, tiger sharks and great white sharks are the three shark species most likely to attack humans.onfidence votes 28. The Bull Shark is found in tropical and subtropical seas around the world, and prefers warm waters. It also lives very close inshore, and often enters fresh water for long periods.

As the eggs develop within the female nurse shark they eventually hatch and the mother gives birth to small live nurse sharks. The nurse shark pups resemble the fully grown nurse sharks with the exception of, of course, their size. A newborn nurse shark measures in at approximately 12 inches long. The average nurse shark mother gives birth to around 20 to 30 pups in a single birthing session.

The bull shark (Carcharhinus leucas), also known as the Zambezi shark or, unofficially, as Zambi in Africa and Nicaragua shark in Nicaragua, is a requiem shark commonly found worldwide in warm, shallow waters along coasts and in rivers.he bull shark is known for its aggressive nature, predilection for warm shallow water, and presence in brackish and freshwater systems including estuaries and rivers. Bull sharks can thrive in both saltwater and freshwater and can travel far up rivers.

Sharks have been attacking humans for over five million years. When swimming, it is an idea to put meat on your wetsuit so that it will repel them. Additionally sharks hate blood in the water, chumming the water will repel the most agressive sharks. Sharks have been evolving since the late 1700's. The shark, the killer of the deep, the dominant predator of the ocean, feared by all who see it, once was the most powerful animal in the world. The shark had long ago walked the earth as man does today.

An important lesson: we need sharks! Where sharks are eliminated, the marine ecosystem loses its balance. In the parts of the ocean where sharks have been fished out of existence, we can see the dangerous result of removing the top predator from an ecosystem. The lesson is important. Sharks are being killed for their fins for shark fin soup, a food that has assumed cultural value but is not important for human survival or health. However, removing the sharks can result in the loss of important foods that we do depend upon for survival.

Most species of sharks are found in the oceans. However, some of them are known to live in bodies of fresh water, like the bull shark which is known to travel up to 4,000 Km up the Amazon River.Sometimes, sharks have been found even in unusual fresh water bodies.nswer: Sharks live in every ocean in the world, however studies published have shown that up to 70% of oceans are free of sharks. Sharks are not territorial like most animals are, so they change frequently their habitat. As many other fish, females do not stay to take care of eggs.

List of sharks. Sharks belong to the superorder Selachimorpha in the subclass Elasmobranchii, in the class Chondrichthyes. The Elasmobranchii also include rays and skates; the Chondrichthyes also include Chimaeras. The first sharks appeared in the oceans over 440 million years ago. Listed below are extant species of shark. Sharks are spread across 512 described species in eight orders. The families and genera within the orders are listed in alphabetical order. Also included is a field guide to place sharks into the correct order.

That kind of number is going to change from shark to shark. The point is that sharks keep growing teeth throughout their lives - no matter how many they lose, they will never run out. Answer 3: Typically a shark has two to three working rows of teeth with 20 to 30 teeth in each row, although a whale shark has about 300 teeth in each row. The replacement rate has not been measured in most sharks but normally the teeth seem to be replaced every two weeks. Click Here to return to the search form.

Hammerhead shark is probably the weirdest type of sharks. There are nine species of hammerhead sharks that inhabit all oceans of the world. Hammerhead sharks can be found both in deep and shallow waters. Out of nine species, two are listed as endangered (great hammerhead and scalloped hammerhead) and one as vulnerable (golden hammerhead) species.

The great white occupies the top slot on the list of ten most dangerous sharks, with the tiger shark coming in a distant second. The remaining seven species on the 10 most dangerous sharks list, in order of their recorded number of unprovoked lethal and non-lethal attacks over the centuries are: 4. The requiem shark (Carcharhinus spp.*) 5. The sand tiger shark (Carcharias tauruss) 6. The blacktip shark (Carcharhinus limbatus)

Swim in a group. Regardless of the danger of sharks, you should avoid swimming alone. If sharks are present, however, it's even more important to travel with a buddy or a group. Sharks are less likely to approach and attack a group of people, and if one member of the group is attacked, help is immediately available. When diving, go straight to the bottom. 2  If you swim on the surface it will make you look like a fish. 3  If you see a shark, exit the water and alert others. 4  If the shark is aggressive, be prepared to fight (punch the shark in the nose).

Shark Diet Variations. Setting the interfamilial variations aside for a moment, the average shark dines on fish, squid and crustaceans [source: Parker ]. When it comes to more specific diet preference, here are some favorites of individual shark species: 1  Hammerheads dine on stingrays. 2  Smooth dogfish sharks like to eat crabs and lobsters. 3  Tiger sharks eat sea turtles. 4  Blue sharks prefer squid.

And Tiger Sharks are very curious, aggressive and have an excellent sense of smell. New Smyrna is known as the shark attack capitol of the world.

Based on cytochrome b genes, Martin and Naylor (1997) concluded the thresher sharks form a monophyletic sister group to the clade containing the families Cetorhinidae (basking shark) and Lamnidae (mackerel sharks).s a result, the long-tailed or common thresher shark, Alopias vulpinus, is also known as the fox shark. The common name is derived from a distinctive, thresher-like tail or caudal fin which can be as long as the body of the shark itself.

I give you the biggest white shark ever seen in front of the cages in Guadalupe Islandâ¦Deep Blue. Shark researcher Mauricio Hoyos Padilla. The latest sighting of her was in water near Mexico's Guadalupe Island. It is estimated at 50 years old and thought to be one of the biggest in the world today. The shark, who is estimated to be around 50 years old, is believed to be one of the largest great white sharks ever seen. Shark researcher Mauricio Hoyos Padilla has been able to tag the shark.

Two of the most popular types of sharks in the world are the great white shark and the hammerhead. The great white is well known for being one of the largest and most dangerous sharks to ever exist. The shark in Jaws is also a great white, which brought a lot of notoriety to the great whites. Hammerheads are also popular based on their unique head shape which is shaped like a hammer.

Fossil Shark Teeth - What are shark teeth made of anyhow? Shark teeth are the most common type of fossil for a number of reasons. First, shark teeth, like most teeth, are made of dentin, a hard calcified tissue that does not easily decompose. Dentin is harder and denser than bone. In a tooth, the Dentin is surrounded by a very hard enamel shell.

Dugong Island and Shark Valley comprise two massive oceanariums, amongst the largest in the world, and have underwater tunnels allowing visitors to examine marine life at close quarters. In the Shark Valley Oceanarium, SEA LIFE Sydney Aquarium houses a large collection of sharks including Lemon Sharks and Grey Nurse Sharks. Some of the sharks weigh up to 300 kilograms (660 lb) and are over 3 metres (9.8 ft) in length. Research and conservation

Sharks: Body Parts. If you look at a shark, you will see it has a number of special adaptations that allow it to fit into an ocean environment. A shark has fins and a streamlined body that help it swim through water.It has gills, which take in oxygen directly out of the water.Because of its gills, sharks can stay underwater and not have to come to the surface to breathe. shark has fins and a streamlined body that help it swim through water.

Tiger sharks are one of the largest carnivores in the ocean. Juveniles have tiger-like stripes, which fade as they grow older. Tiger sharks are blue or green in color with a light yellow or white under-belly.This speices has a large blunt nose on the end of a wedge-shaped head.iger sharks are some of the largest predators in the ocean and have few species feed on them. Some juvenile tiger sharks, however, fall prey to other sharks. Female tiger sharks gives birth in a nursery, which provides protection during the birthing process and to pups in the absence of parents.

The iridescent shark (Pangasianodon hypophthalmus) is a species of shark catfish (family Pangasiidae) native to the rivers of Southeast Asia. It is not a shark. It is found in the Mekong basin as well as the Chao Phraya River, and is heavily cultivated for food there.he fish is named for the glow or iridescence exhibited in juveniles, as well as the shark-like appearance of this and other shark catfish. It is also known as Siamese shark or sutchi catfish in the aquarium hobby. Adults reach up to 130 cm (4 ft) in length and can weigh up to a maximum of 44.0 kg (97 lb).

Smell is probably the most important shark sense, so much so that sharks have been referred to as swimming noses [source: SeaWorld]. There are some impressive statistics to back this up, too. A shark can sniff out fish extracts that make up only one part for every 10 billion parts [source: Elasmodiver]. Other research shows sharks are able to respond to one part blood for every one million parts of water; this is like being able to smell one teaspoon of something in a swimming pool [source: Shark Trust]. What's more, sharks can smell these small amounts from hundreds of meters away [source: SeaWorld].

A great white shark, for example, would be able to detect a single drop of blood in an Olympic-size pool. Most sharks can detect blood and animal odors from many miles away. Another amazing thing about a shark's sense of smell is that it's directional. The twin nasal cavities act something like your two ears: Smell coming from the left of the shark will arrive at the left cavity just before it arrives at the right cavity. In this way, a shark can figure out where a smell is coming from and head in that direction. Sharks also have a very acute sense of hearing.

Sharks live in every ocean. Sharks swim in every ocean of the world, from warm tropic waters to icy polar. seas. Some live in the deep, dark waters of the ocean, while others bask in sunlit. waters close to the surface. Some prefer the high seas, others live in water closer. to shore. A few sharks even swim up rivers, and at least one species, the bull. shark, is sometimes found in fresh water lakes. 2. All sharks look alike. No, many kinds of sharks which live in the open ocean have torpedo-shaped. bodies.

The bull shark, also known as the Zambezi shark in Africa, and Lake Nicaragua shark in Nicaragua, is a requiem shark commonly found worldwide in warm, shallow waters along coasts and in rivers. The bull shark is known for its aggressive nature, predilection for warm shallow water, and presence in brackish and freshwater systems including estuaries and rivers. Bull sharks can thrive in both salt and fresh water and can travel far up rivers. They have been known to travel up the Mississippi River as far as Alton, Illinois, about 700 miles (1100 km) from the ocean.

Oceanic whitetip sharks, Carcharhinus longimanus (Poey, 1861), aka white-tipped shark, whitetip oceanic shark and whitetip shark, are large stocky sharks with a huge, rounded first dorsal fins and long, wide-tipped pectoral fins.ceanic whitetip sharks feed on oceanic bony fishes, including tuna and mahi-mahi (dolphinfish, Coryphaena hippurus), threadfins, stingrays, sea turtles, sea birds, gastropods (snails), squid, crustaceans, mammal carrion and sometimes even garbage.

There is considerable variation between species in the length of pregnancy. At least one group of fish has been named after its pregnancy characteristics. The surfperch, genus Embiotoca, is a saltwater fish with a gestation period of three to six months.This lengthy period of pregnancy gives the family its scientific name from the Greek embios meaning persistent and tokos meaning birth.xamples of ovoviviparous fish are many of the squaliform sharks, which include sand sharks, mackerel sharks, nurse sharks, requiem sharks, dog sharks and hammerheads, among others, and the lobe finned coelacanth.

Regardless sharks are cold blooded, they live either in warm, temperate and cold waters. Some species live mainly in cold waters, while some others prefer warmer waters. SHARK MIGRATION. One thing is for sure; sharks migrate to find new sources of food and they can travel up to hundreds of miles to do that. Most species of sharks live in the oceans. However, some of them are known to dwell in bodies of freshwater, like the bull shark which travels up to 4,000 Km up the Amazon River. Sometimes, sharks reach freshwater bodies; this could be the result of the destruction of their habitat by human activities.

It was found that the bull shark stayed at the mouth of the river independent of the salinity of the water. The driving factor for a bull shark to be in freshwater or saltwater is its age; as the bull shark ages the tolerance for very low or high salinity increases.ne way the bull shark is able to conserve energy is that when the tidal flow changes, the bull shark uses the tidal flow in order to conserve energy as it moves downriver. Another way for the bull shark to conserve energy is to decrease the amount of energy needed to osmoregulate the surrounding environment.

Fossil Shark Teeth. Shark teeth are made of a solid substance called dentin. This material is slow to decompose, which is part of the reason why fossil shark teeth are so plentiful. When a shark loses a tooth, it ends up on the bottom of the ocean, where it's covered with protective layers of sediment.hark teeth are made of a solid substance called dentin.

There are more than 500 species of sharks swimming in the worldâs ocean. Yet when most people think of these cartilaginous fish, a single image comes to mind: a large, sharp-toothed and scary beast. That generalization does sharks a huge disservice, as they have far more variety than that.oday, fins are the most valuable part of a shark. The targeted shark-fin fisheries around the world are trading the fins of between 26 to 73 million sharks every year (according to a 2006 estimate) with a worth of $400-550 million. Driving this trade is the demand for and consumption of shark fin soup in Asia.

Last year there were a total of 47 shark attacks in the U.S., with two of them ending in a fatality. The states with the highest number of shark attacks that occurred last year, according to the International Shark Attack File, are as follows: Florida with 23 attacks, Hawaii with 13 and South Carolina with six.California, North Carolina, Texas, Oregon and Alabama each reported one shark attack.he states with the highest number of shark attacks that occurred last year, according to the International Shark Attack File, are as follows: Florida with 23 attacks, Hawaii with 13 and South Carolina with six.

Geographic Range. Tiger sharks are found in many subtropical and tropical waters, primarily from 45Â°N to 32Â°S. Tiger sharks have been sighted from the eastern coast of North America to the eastern coast of Brazil. This includes the coasts of southern North America, Mexico, and Latin America along the Gulf of Mexico.iger sharks are some of the largest predators in the ocean and have few species feed on them.

Some can get even bigger than that, for instance one tiger shark was found to be 55 meters long which is about 18 feet long.

Aggressive overfishing threatens to push some shark species to extinction, and a new study puts annual shark deaths at 100 million. Our analysis shows that about one in 15 sharks gets killed by fisheries every year, study leader Boris Worm, a professor of biology at Canada's Dalhousie University, said in a statement. With an increasing demand for their fins, sharks are more vulnerable today than ever before.. Based on available data for shark deaths and estimates of unreported illegal catches, the researchers estimated that 100 million sharks were killed in 2000 and 97 million in 2010.

The skin of an adult whale shark can be as thick as 4 inches (10 cm) and has the consistency of strong rubber, which limits possible predators to killer whales, great white sharks, tiger sharks and humans. Color. Whale shark has a two-toned pattern of light spots on its dark gray back with a white underside. Each whale shark has its own individual spot pattern; like human fingerprints, no two are exactly alike. Teeth. Teeth of the whale shark are tiny and pointed backward; they are thought to have no function in feeding.

Bonnetheads Can Survive On Seagrass Alone, Study Finds By Suman Varandani @suman09 On 01/11/18 AT 6:17 AM Sharks are infamous as meat eaters who often prey on sea creatures and sometimes humans. However, a new study has found that there is a species of shark that can survive on a vegetarian diet. Meet the bonnethead shark, a member of the hammerhead shark genus Sphyrna in the family Sphyrnidae. A study, led by Samantha Leigh, a doctoral candidate at the University of California, Irvine, found that these sharks are able to survive on a diet of seagrass, a plant that grows on the ocean floor. The study was based on a research conducted 10-years ago, which examined the sharks' stomach contents.

Ever wondered what species of shark you just caught? Or, what type of shark is swimming just off the beach near the sand bar? I know I've had both of the questions pop up on trips to the Alabama gulf coast. Here are the 16 most common sharks that swim the coastal waters of Alabama. See the descriptive information under each photo to help you identify one shark from another. The list was compiled with the help of Dr. Bob Shipp. Dr. Shipp is a leading authority on the fishes of the Gulf of Mexico.

Shark lifespan vary by kind. Although the majority of types live 20 to 30 years in the wild, there are some kinds that live much longer than others. For example, the spiny dogfish has one of the longest lifespan at more than 100 years, while the blue shark in the wild has an average lifespan of 15-16 years.andbar sharks or Brown sharks are considered to live between 20 and 30 years. Research made by Joung (2004) identified to be about 20 years of age.

1 The skull of a shark is made of only 10 cartilaginous elements while a bony fish skull has about 63 bones. 2  Bony fish have pleural ribs formed from dermal bone and sharks lack these ribs. 3  Unlike bony fish that have a protective bony plate covering their vulnerable gills, the gill slits of a shark are exposed and visible.

Sharks - Skeleton. The skeleton of the shark has evolved and adapted to suit and aid the habitat, migration, hunting habits and diet of these acclaimed carnivores. Unlike terrestrial animals, humans, and even other marine animals, sharksâ skeletons are made purely of cartilage and connective tissue, or muscle. There is no bone. This type of skeleton means that the shark is lighter, as cartilage is about half the density of bone. This is important because, unlike other fish, the shark has no swim bladder to prevent it from sinking to the bottom of the ocean.

Porbeagle Shark Facts. The Porbeagle Shark, also called Lamna nasus, comes from the family of Lamnidae sharks. It is mostly found in cold and temperate waters of the North Atlantic Ocean. This is a species of the mackerel shark and is a close relative of the salmon shark.The Porbeagle can reach over 8 feet (2.5 meters) in length and can gain a weight of 135 kilograms or 298 pounds. They are normally white at the bottom and grey on top giving it some nice camouflage for hunting.ou can mostly find this shark in the North Atlantic on the coasts of Greenland, Canada, Russia and Scandinavia. Further south, this shark can be spotted near Bermuda, New Jersey, Madeira, Brazil, Chile and Morocco. It has also been sighted in the Mediterranean Sea. The Porbeagle is known to migrate long distances.

Bull sharks are large and stout, with females being larger than males. The bull shark can be up to 81 cm (2.66 ft) in length at birth. Adult female bull sharks average 2.4 m (7.9 ft) long and typically weigh 130 kg (290 lb), whereas the slightly smaller adult male averages 2.25 m (7.4 ft) and 95 kg (209 lb). While a maximum size of 3.5 m (11 ft) is commonly reported, a single record exists of a female specimen of exactly 4.0 m (13.1 ft). The maximum recorded weight of a bull shark was 315 kg (694 lb), but may be larger. Bull sharks are wider and heavier than other requiem sharks of comparable length, and are grey on top and white below.

The typical lifespan in the wild for Hammerhead Sharks is from 20 to 30 years approximately. Sandbar sharks or Brown sharks are considered to live between 20 and 30 years. Research made by Joung (2004) identified to be about 20 years of age.lthough the majority of types live 20 to 30 years in the wild, there are some kinds that live much longer than others. For example, the spiny dogfish has one of the longest lifespan at more than 100 years, while the blue shark in the wild has an average lifespan of 15-16 years.

Shark lifespan vary by kind. Although the majority of types live 20 to 30 years in the wild, there are some kinds that live much longer than others. For example, the spiny dogfish has one of the longest lifespan at more than 100 years, while the blue shark in the wild has an average lifespan of 15-16 years.ome scientists believe that the life expectancy of the Great White Sharks is around 30 years (Levine, 1988) but other research indicates that they can reach up to 40 years. The lifespan of Tiger Sharks in the wild is believed to be 27 years in average, although some may live up to 50 years of age.

Fish Home. Dogfish sharks are characterized by smooth dorsal fin spines, teeth in upper and lower jaws similar in size. The spiny dogfish or piked dogfish is a type of small shark and one of the best known of the dogfish. Just the Facts: The spiny dogfish has dorsal spines, no anal fin, and white spots along its back.They can grow up to 107 cm and are greyish brown in color.he spiny dogfish or piked dogfish is a type of small shark and one of the best known of the dogfish.

Whale sharks (a type of shark) are bigger than killer whales (actually dolphins). Whale sharks average 25 feet (7.6 m) long, and can weigh up to 15 tons (females bigger than â¦ males). Killer whales average 19-22 ft (5.8 to 6.7 m) for males, and 16-19 ft (4.9 to 5.8 m) for females.iller whales (orcas) are at the top of the food chain and are known to eat sharks. They also eat other marine mamm â¦ als such as seals, sea lions, walruses and even smaller whales. They also feed on birds, sea turtles, penguins, polar bears, reptiles, octopus and even land mammals.

By what name did the crew of Jaws call the mechanical shark? What was the nickname of the mechanical shark in the movie Jaws? They used three different mechanical sharks, and they were all nicknamed Bruce, after Steven Spielberg's lawyer.

OK if someone tells you how many sharks are in the world they are lying. Oceans+Seas are twice larger than the landmass on this planet and most of it is still unknown to man. So there is no way in hell that anyone could know how many sharks are in the water. @@@@. If you mean how many different species of shark then:

There is over 350 species of sharks and more are being reported all the time, how ever there are also roughly 400 species of rays which are close relatives to the sharks. well my point is that each shark has its own speed if you would like to post a different question a little more specific i would gladly answer it!

Life Cycle of Sharks. Sharks have been the most feared and wild marine creatures. These animals have been prowling in the oceans for around 400 million years and have evolved into 440 different species. Sharks are known to live for many years.

Fins. Sharks, as all fish, use their body and tail in a side to side motion to move through the water. Shark fins are rigid not flexible, and are supported by rods made of cartilage. Sharks have five different kinds of fins.

What do sharks eat? With so many species, sharks have evolved to an extent that will literally eat anything that moves. Their eating habits vary widely and depend on their habitat, and the variety of food and prey that is available therein. Sharks also adapt quickly when they find themselves in different habitats and situations.

There are 440 different species of sharks in the world today classified into eight different orders described below with some examples of known sharks species for each group.

Many sharks, like blue sharks, hammerheads, and spiny dogfish, spend much of their lives segregated by gender and age (Campagno et al. 2005). Scalloped hammerhead sharks form different groups: Subadult females live offshore with similar-sized individuals.

Mandalay Bay Shark Reef description. At more than 105,000 square feet, Shark Reef is home to more than 1,200 different species of sharks, tropical and fresh water fish, reptiles, marine invertebrates and rays totaling about 2,000 animals among 2 million gallons of seawater.

Contributed by Amber I wanted to stress that these fish are brackish meaning they need salt. Not only do they need salt they need to have a tank all of their own. I placed mine in a tank made up of different types of unusual fish such as a columbian shark catfish, cory catfish, albino shark, dragon fish or Goby.

A lot of things. For one, Whale sharks are fish and use gills to breathe. Blue whales are mammals. The blue whale is also bigger than the whale shark. The tail structure is also different if you watch the whale shark swim, it uses its tail in a side to side motion while the blue whale uses a up and down movement.

What do people taste like to sharks? To sharks humans taste like sweet beef,no im not kidding, to every animal humans taste different and to sharks we taste like sweet beef. I disagree with the above answer, beâ¦cause a cannibal in Japan whose father was famous and got him out of jail said that people taste like tuna.

This is the trophic pyramid for the great white shark. The great white shark trophic pyramid starts with kelp, that then gets eaten by different kinds of zoo plankton. After the zoo plankton come the small fish which get eaten by the bigger fish. The tip of the pyramid is the shark which eats the big fish.

If you aren't sure what type of food a certain shark species eats, check out its mouth. Different sharks have specialized teeth tailored to their preferred prey. Great whites have razor-sharp, triangular fangs to slice through the thicker, fattier flesh of larger fish and sea mammals.

The white shark is known for its curiosity and may examine solitary and vulnerable objects to determine if they're edible. Once the shark has spied something to try, it makes its approach. Scientists have identified several different ways the great white moves towards its prey: 1  An underwater approach is used most often. 2  The shark swims under the surface until it's just a few feet away from its prey.

Currently there are approximately 400 described species of sharks, however new species are being described all the time. In addition, there are around 400 species of rays, a close relative of sharks. Like all living things that humans know about, they are classified by kingdom, phylum, class, order, family, and species. Sharks all belong to the same class, Chondrichthyes, but they are divided into 8 different orders.

Sharks live in all oceans down to depths of 2,000 meters (6,600 feet). Usually, they do not live in freshwater with the exception of the bull shark and river shark.ustralia is a shark-infested country, with three different grades of probabilities-mild (Northern Territory, Tasmania and Cocos Islands), moderate (Western Australia, South Australia and Victoria) and severe (Queensland and New South Wales).

The frilled sharks off southern Africa were described as a different species, C. africana, in 2009. The frilled shark inhabits the outer continental shelf and upper to middle continental slope, seeming to favor upwellings and other biologically productive areas.he gestation period may be as long as three and a half years, the longest of any vertebrate. Litter sizes vary from two to fifteen, and there is no distinct breeding season. Frilled sharks are occasional bycatch in commercial fisheries, but have little economic value.

A cartilaginous fish's skin is covered in placoid scales, or dermal denticles, tooth-like scales different from the flat scales (called ganoid, ctenoid or cycloid) found on bony fish.ifferent shark species may have different numbers of gill slits. Cartilaginous fish may also breathe through spiracles, rather than gills. Spiracles are found on top of the heads of all rays and skates, and some sharks.

Killer whales feed on a large variety of marine animals. Thirty fish species, including salmon, herring, and shark species are hunted. Even the largest shark, the whale shark, falls prey to the orca. Five seal species, seven seabird species, sea lions, penguins, squid, sea otters, and sea turtles are common prey. Larger aquatic mammals, like dugongs are also hunted. Fascinatingly, 24 different species of cetacean are hunted by orcas.

USA and Australia are the most sharks infested countries in the world. From year 1580, a total of 572 shark attacks killed 153 people in Australia.In the United States, 1100 attacks have already caused 35 deaths. Florida and California have been suffering more than any other US state.ustralia is a shark-infested country, with three different grades of probabilities-mild (Northern Territory, Tasmania and Cocos Islands), moderate (Western Australia, South Australia and Victoria) and severe (Queensland and New South Wales).

Dumbo octopus is a type of octopus named after Walt Disney's famous character Dumbo the elephant because of the ear-like fins. There are around 37 different species of dumbo octopi.ain predators of dumbo octopi are sharks and killer whales. Dumbo octopus eat different type of crustaceans, bivalve, worms on the sea bottom and copepods (that are part of the zoo-plankton) when they swim near the surface of the water.

Answer: Cartilaginous fish are fish that have a skeleton made of cartilage, rather than bone. All sharks, skates, and rays (e.g., the southern stingray) are cartilaginous fish. These fish all fall into the group of fish called the elasmobranchs.n addition to the difference in their skeletons, cartilaginous fish have gills that open to the ocean through slits, rather than the bony covering that is present in bony fish. Different shark species may have different numbers of gill slits.

Called a cephalofoil, each shark's head can have a slightly different appearance. The names of some species describe the different bumps and creases in their cephalofoils; the scalloped hammerhead, for example, has ridges all along their cephalofoils. At an average size of 10 to 13 feet and weighing up to 1,000 pounds, the great hammerhead shark is the largest of the group. The bonnethead is the smallest, with an average size of just 3 feet long and weight of less than 7 pounds. The scoophead is also very small, with its cephalofoil sometimes representing one-third the size of its entire body.

Some common kinds of shark include the hammerhead shark, the great white shark, the tiger shark, and the mako shark.

Sharks will kill and eat other sharks, or anything else that looks like fresh food. So â¦ if a shark is killed, it will often be immediately consumed by other sharks, along with anything and everything else in the vicinity. Not necessarily true, there is evidence that certain sharks will eat carrion.

Sharks are not carrion eaters; they do not eat things that have been dead for a while. Sharks will kill and eat other sharks, or anything else that looks like fresh food. So â¦if a shark is killed, it will often be immediately consumed by other sharks, along with anything and everything else in the vicinity.

While bull sharks may be the most menacing, another shark is probably responsible for the most human shark bites, according to Burgess. In 2013, the United States had a total of 47 shark attacks, according to the International Shark Attack File.

Swai Fish. The Swai Fish, or Iridescent Shark, is a rather unremarkable fish that is typically farmed in Asia. However, it seems to create a bit of controversy in what contexts it appears. Whether it is to be kept in an aquarium or to be eaten at the dinner table, the Swai Fish has opposing viewpoints.s a juvenile, the Swai Fish radiates a glow from the edges of its fins, thus given the name Iridescent Shark. It can grow up to four feet in length and weigh up to nearly 100 pounds. They are omnivores and will eat other fish, crustaceans, and different types of water plants.

There are many species of sharks in the ocean. Sharks are one of the better known predators in the sea. Many sharks have sharp teeth that are used to catch their food. The most dangerous shark is the great white shark, which can grow to over 20 feet long.

The whale shark is one of three large filter-feeding sharks; the others are the megamouth shark (Megachasma pelagios) and the basking shark (Cetorhinus maximus). The whale shark forages for food at or near the surface of the ocean.

Fact Sheet: Spiny Dogfish. The real spiny dogfish (Squalus acanthias) . Â© Shark Info / J. Stafford-Deitsch. The spiny dogfish is known primarily by virtue of its largest representative, the real spiny dogfish, Squalus acanthias. But the name spiny dogfish is not reserved for this one specific species alone.It covers an entire family of spiny dogfish including, for example, such different forms as Greenland sharks or cookie-cutter sharks.he distribution of the real spiny dogfish is limited (see map) since these animals generally prefer a water temperature ranging between 7 and 15 degrees. Nevertheless, they may well have the largest population of any given shark species.

Using mitochondrial DNA, a phylogenetic tree of the hammerhead sharks showed the winghead shark as its most basal member. As the winghead shark has proportionately the largest hammer of the hammerhead sharks, this suggests that the first ancestral hammerhead sharks also had large hammers.

Do other sharks eat whale sharks? Sharks may try to eat whale sharks if there is not a lot of other food, but it would be very hard and probably not work because whale sharke are the largest fish on Earth and â¦they kill other fish and even sharks very easily.

â¢ Hammerhead Sharks. There are several species of hammerhead sharks, which are in the family Sphyrnidae. These species include the winghead, mallethead, scalloped hammerhead, scoophead, great hammerhead and bonnethead sharks. These sharks differ from other sharks, as they have very unique hammer-shaped heads.

Bull shark. The bull shark (Carcharhinus leucas), also known as the Zambezi shark or, unofficially, as Zambi in Africa and Nicaragua shark in Nicaragua, is a requiem shark commonly found worldwide in warm, shallow waters along coasts and in rivers.

1 Only 3 shark species (the whale shark, the basking shark, and the megamouth shark) are filter feeders, straining their prey from the water column.  The whale shark can reach a length of 40 feet or more and weighs 20 or more tons.

Sand sharks, also known as sand tiger sharks, grey nurse sharks or ragged tooth sharks, are mackerel sharks of the family Odontaspididae. They are found worldwide in temperate and tropical waters. The three species are in two genera.

Some sharks can live in fresh water for a limited amount of time. Sharks have been known to swim up rivers such as the Mississippi, but only certain species of sharks have the ability. Bull sharks have been known to swim up rivers. They have a higher tolerance for fresh water than most other sharks.

Commercial shark-finning is a practice where sharks are caught and their fins are cut off, then the body of the shark is discarded. Shark finning kills an estimated 100 million or more sharks globally per year. Bycatch. Bycatch in commercial fisheries is also a major threat.

The oldest shark fossils. The oldest fossilized evidence of prehistoric sharks comes from shark-like scales that date to 455 million years ago during the Ordovician Period, in Colorado. Some paleontologists do not agree that these scales are sufficiently shark-like to pronounce them sharks.

SHARKS LIFE CYCLE. Each shark species has its own expected life span and it is difficult to set an average for sharks as a whole. However, very broadly speaking, most sharks live for between 20 and 30 years. The Spiny Dogfish lives for over a century, and some Whale Sharks have been known to do the same.

Bull shark. The bull shark (Carcharhinus leucas), also known as the Zambezi shark or, unofficially, as Zambi in Africa and Lake Nicaragua shark in Nicaragua, is a requiem shark commonly found worldwide in warm, shallow waters along coasts and in rivers.

Due to public demand and the wow factor, aquariums want to include rarer sharks, such as the great white shark (Carcharodon carcharias), tiger shark (Galeocerdo cuvier), scalloped hammerhead shark (Sphyrna lewini), and whale shark (Rhincodon typus), in their exhibits.

The Thresher shark, similar to its smaller brother the 'Bigeye Thresher Shark', is another large breed of shark that can grow as long as 18 feet. THe Thresher shark is the 8th biggest shark known to man and is found in tropical oceans around the world.

Generally sharks have only one layer of tesserae, but the jaws of large specimens, such as the bull shark, tiger shark, and the great white shark, have two to three layers or more, depending on body size. The jaws of a large great white shark may have up to five layers.

As the name suggests, certain sharks feed by filtering the food matter, such as zooplankton, and other small fish from the water through a process where the water is passed through a detailed filtering mechanism. Among the shark subclass, whale shark, megamouth shark, and basking shark are filter feeders.

Live-Bearing Sharks. About 60% of the shark species give birth to live young. This is called viviparity. In these sharks, the young remain in the mother's uterus until they are born. The viviparous shark species can be further divided into the ways the young sharks are nourished while in the mother:

Click Here to see the Complete List of Most Shark Infested Beaches. Some common sharks include bull sharks that are found in shallow waters. Great White Sharks prefer to stay in deep waters. Blacktip Sharks can be found in groups and appear in shallow water.

The name bull shark comes from the shark's stocky shape, broad, flat snout, and aggressive, unpredictable behavior. In India, the bull shark may be confused with the Sundarbans or Ganges shark. In Africa, it is also commonly called the Zambezi River shark or just Zambi.

Only sharks that swim near the bottom of the sea eat starfish. Nurse sharks, horn sharks and Port Jackson sharks are all known to eat them. All of these sharks have strong enough jaws to crush the hard bony outer skeleton of the starfish and eat the flesh underneath.

The carpet sharks (Orectolobiformes) are so-called because many of these species have ornate carpet-like skin patterns. 1  They include the whale shark, wobbegongs, bamboos sharks and nurse sharks. 2  Sawsharks (Pristiophoriformes) are 5-foot-long, bottom-dwelling sharks with toothy saw-like snouts.

Sharks are carnivorous and may be found in all seas. They associate humans with food. Sharks do not usually live in fresh waters, but there are exceptions: the river shark and the bull shark. Most sharks are found in 2,000 meters (7,000 ft) level, in warm environments, but they can also be seen in shallow waters.

Lemon shark, bonnet heads, dusky sharks, white and black tip reef sharks, and a baby bull shark! And a 8 foot moray eel curled up in the rocks you can't see. Two japanese leopard sharks were just taken out previous to the video.

Most sharks are cold-blooded. Some, like the Mako and the Great white shark, are partially warmblooded (they are endotherms). Cold blooded although if you've ever seen a Great White Shark hunt sea lions you'd be thinking they would have to be hotblooded. Actually the Salmon Shark is a warm blooded shark.

The Tiger Shark is the 3nd most aggressive shark. It has been know to have human body parts in the stomach. These sharks generally hunt at night and will devour anything that comes in their way. 4. The Oceanic Whitetip Shark has been known to follow ships and wait for a meal. Most aggressive shark towards humans.

Although all sharks are carnivorous, meaning they eat other animals, nurse sharks fall into a category of laid back, easy-going sharks that prefer to swim awhile and then rest awhile. Nurse sharks (Ginglymostoma cirratum) may in fact be considered the couch potato of the shark world.

The Bluntnose sixgill shark, Hexanchus griseus, is the ninth biggest shark in the world and is often referred to as a cow shark. The Bluntnose sixgill shark is a member of the Hexanchidae family; most of their relatives are extinct. These sharks skin color's can range from tan/brown to nearly black in color.

For most of the smaller species of dolphins, only a few of the larger sharks, such as the bull shark, dusky shark, tiger shark and great white shark, are a potential risk, especially for calves. Some of the larger dolphin species, especially orcas (killer whales), may also prey on smaller dolphins, but this seems rare.

Interestingly, the largest shark species, the whale shark, does not hunt at all. Enormous whale sharks, megamouth sharks and basking sharks filter feed on plankton. These species have specialized gills that sift through water to extract the microscopic algae and sea creatures that comprise plankton.

Tiger Sharks are incredibly impressive and large sharks which can reach a length of more than six meters. Tiger Sharks have the broadest food spectrum of all sharks. Apart from sea turtles, seals, sea lions, other sharks, whales, and sea birds, they also eat invertebrates, garbage and carrion.

A: Depending on the species, sharks either lay eggs or give birth to live young. Sharks that lay eggs are oviparous, and sharks that give birth to live young are viviparous. Viviparous sharks are further divided into placental and aplacental categories, meaning the shark pups either have a placenta or not.

Shark. Shark The huge water fish is fondly eaten for its fins. Shark is common seafood in many countries including Japan and Australia. Shark fish is eaten in fish and chips in parts of New Zealand and Australia. In many countries, shark meat is sold under the common name of fish.

The blue shark is considered to be one of the most dangerous sharks in the waters. It has been known to attack people, which makes it one of species of shark that people most fear. Blue sharks can grow up to 12 feet long so this is no small shark to be trying to get away from. Due to the speed and the strength of it very few of its prey have a chance of survival.

One of the five species belonging to the family Lamnidae, the salmon shark is a close relative of the Atlantic and Southern Pacific porbeagle shark (Lamna nasus). Together with the white shark and two species of mako shark, the salmon and porbeagle sharks share recognizable features that are peculiar to the lamnids.

The gills are crucial to a sharks breathing system. By opening its mouth, water is drawn into the shark. The open mouth gives the appearance of a smile in many sharks. When a shark closes its mouth, the water is forced over its gills and the tiny blood vessels in shark gills absorb oxygen from the water.

White Shark redirects here. For the novel, see White Shark (novel). The great white shark (Carcharodon carcharias), also known as the great white, white pointer, white shark, or white death, is a species of large mackerel shark which can be found in the coastal surface waters of all the major oceans.

Animal Species:Bull Shark, Carcharhinus leucas Valenciennes, 1839. The Bull Shark is one of the few sharks that are potentially dangerous to people and is probably responsible for most of the shark attacks in and around Sydney Harbour. The species is also the only widely distibuted shark that stays in fresh water for long periods of time to feed and breed.

Broadcasting. 1  1988: The first ever Shark Week premiered in July 1988, with the first show to air being Caged in Fear. 2  1989: Due to the success of the first Shark Week, Discovery decided to continue it. 3  1990: New shows that aired included Shark!: The World of Sharks and Barracuda and Sharks: Hunters of the Oceans.

Bull sharks, however, can swim up fresh water rivers rather easily. Most experts believe the Matawan shark was a bull shark. Officially, bull sharks have made it up the Mississippi as far as Illinois. In the town of Alton, Illinois, which is above St. Louis, two commercial fisherman caught a bull shark in the river.

3. Great White Shark. The great white shark, Carcharodon carcharias, has got to be one of the worlds most well known vicious sharks. These sharks have been known to grow as long as 26.2 feet and weigh as much as 5000 lbs! The Great White shark is the last surviving member of its species genus, Carcharodon.

Interesting Facts About Shark: 1  Sharks do not have roots in their teeth for attachment to the gums. 2  All sharks lose one tooth a week, at least. 3  Most of the times shark teeth are stuck to their prey or come out while eating. So they lose their teeth. 4  In most of the animals, only lower jaw can move. But in sharks, both jaws are movable.

Sharks range in lifestyle and demeanor from the fast, aggressive shortfin mako to the more relaxed and sedentary bottom dwelling sharks. Although all sharks are carnivorous, meaning they eat other animals, nurse sharks fall into a category of laid back, easy-going sharks that prefer to swim awhile and then rest awhile.

Shark Within A Shark Picture By ORB LAB Will Blow Your Mind (PHOTO) Sharkception! Researchers at the University of Delaware's ORB LAB posted this photo of a shark within a shark on Facebook in late July. The lab memebers were using a small fish called a menhaden as bait to recapture sharks they had previously tagged.

1 Many Everyday Activities Are More Dangerous Than Diving With Sharks. 2  Deadly Boating and Driving Accidents Are More Likely Than Deadly Shark Attacks. 3  Even Shark-Related Injuries Are Very Rare. 4  Further Reduce the Risk of a Shark Attack While Diving. 5  The Take-Home Message About Diving With Sharks.

Blood and human waste attract sharks. 6. Sharks are creatures of habit. Do not swim in areas where a shark attack has recently occurred, since the same shark, or others, may still frequent the spot. 5. Try to swim on sunny, clear days. Foggy mornings and dusk may cause a shark to confuse you with prey. 4.

Almost all sharks have sub-terminal mouths except for the whale shark and megamouth sharks. Skimming above the sandy surface, the sharks pluck up crabs, clam siphons, fish eggs, and the burrowing, hot-dog-shaped fat innkeeper worm. As leopard sharks get older, they start eating more fish and fewer crabs.

Many people want to know what do sharks eat, but there is not a simple answer to that question. The diet of a particular shark can heavily depend on a variety of factors including habitat, location, food availability, shark species, and the size of the shark. The general answer to What do sharks eat is almost anything, but it is heavily dependent on the tastes of each species and the food that is available where it lives.

There are many species of sharks, over 400 in fact(and more are being found). Out of those 400+ most shark species are able to both buccal pump(pump water through their gills) and ram ventilate(swim to force water through their gills). There are some sharks that are only able to do one or the other though. Species that are primary low activity may not use ram ventilation much if at all, these species include the nurse shark and other similar sharks.

It looks very similar to a mako shark, and use to be categorized as a mako shark. Many people, out of habit, still call these fossil teeth mako sharks. 2 White Shark-Carcharodon hastalis [narrow form] - Calvert Cliffs of Maryland.

How Long Do Great White Sharks Live. Many sharks can live for about 20 to 30 years, with some species are known to live a fairly longer life. The lifespans of large sharks are greater than that of the smaller sharks. Great white shark reaches its maturity at the age of 15 and it has the lifespan of 25 to 30 years.

Quick Answer. Depending on the species, sharks either lay eggs or give birth to live young. Sharks that lay eggs are oviparous, and sharks that give birth to live young are viviparous. Viviparous sharks are further divided into placental and aplacental categories, meaning the shark pups either have a placenta or not. Continue Reading

Shark Week. Shark Week is an annual, week-long TV programming block created by Tom Golden at the Discovery Channel, which features shark-based programming. Shark Week originally premiered on July 17, 1988. Featured annually, in July and/or early August, it was originally devoted to conservation efforts and correcting misconceptions about sharks.

The smallest shark, the dwarf shark, is only 25 cm (10 inches) long. The basking shark is the largest shark in Atlantic Canada, routinely reaching lengths of 8-9 metres. The largest confirmed great white shark caught in Canada was more than 5 metres long. It was caught off of PEI in 1983.

Sharks maintain several rows of growing teeth to replace any damaged and missing teeth in the two or three rows of mature teeth. The amount of teeth a shark has varies from one species to the next. For example, a whale shark has about 300 teeth in each row, whereas the great white shark has approximately 50 teeth total. Learn more about Sharks

Sharks & Rays. Whale Shark. The largest fish in the world is the graceful, harmless Whale Shark. Though they reach the size of a school bus, Whale Sharks eat tiny plankton and fish eggs, which they filter feed as they swim slowly along with their giant mouths wide open. They are one of only three species of filter feeding sharks.

Most shark species breathe by swimming. with their mouths open which allows the. water to pass over the gills. Some sharks. like nurse, angel and lemon sharks have. strong neck muscles that pump water over the. gills, allowing the shark to breathe while resting. on the ocean bottom. Sharks are fish, and therefore breathe through the use of. gills, slit-like openings on the sides of their head.

Sharks' eyes are protected when attacking prey. Also unlike humans, shark eyelids serve to protect the eye when attacking prey. Some sharks have a nictating membrane, or a clear membrane that covers and protects the eye when a shark bites its prey. Sharks like the Great White, lacking a nictating membrane, roll their pupils back in their heads for protection when feeding.

Shark Attack 2 ( 2001 ) - The mutant sharks from Dr. Craven's experiments in Shark Attack 1 are back, this time choosing Cape Town, South Africa as their hunting ground.

Great white shark. The great white shark (Carcharodon carcharias) is a species of shark. They are world's largest living predatory fish. Mature sharks may grow up to 6.4 m (21 ft) in length and 3,324 kg (7,328 lb) in weight). There also have been a few reports of great white sharks measuring over 8 m (26 ft).

Sharks aren't really afraid of dolphins; that's a common misconception that has led people to believe that when dolphins are present in an area, there will not be any sharks nearby. In fact, many species of shark and dolphin actually hunt and eat the same prey items, so the presence of dolphins often indicates the presence of sharks as well. Dolphins and sharks are two ocean predators who have to compete for food and territory.

According to the International Shark Attack File, the Tiger shark ranks No. 2 behind the white shark in the number of reported attacks on humans. The shark-monitoring group notes that the animal's large size and voraciousness qualify it as a formidable ocean predator. Surfers and swimmers need to know that Tiger sharks tend to be both curious and aggressive when they spot humans in the water.

Answers. Best Answer: Sharks are found all around the globe from the north to the south in all seas, they generally do not live in freshwater except for a few exceptions like the bull shark and the river sharks which can swim both in seawater and freshwater.hough depending on the climate they live in greatly depends on how they behave. the greenland shark one of the biggest sharks in the world, live up north, but it moves really slowly conserving energy.

Zebra sharks are most commonly found in the Indian and South Pacific oceans. Zebra sharks can grow to nearly 3 meters in length and can get to be 30 years old in the wild. Zebra sharks that are kept in captivity generally do not exceed 15 years of age. Zebra sharks can be identified by the yellow spots that are present on the back of the zebra shark.

Are sharks really dangerous? After all, you're more likely to be killed by lightning or faulty wiring on your Christmas tree than by a shark [source: McCarthy]. Death by bee sting occurs far more often than death by shark [source: Burgess]. In the water, you're more apt to drown or be injured by your own surfboard than be hurt by a shark [source: Martin]. Researchers love to throw around statistics like these to redeem sharks.

Bull shark. The Bull shark (Carcharhinus leucas), or Zambezi shark, is a species of shark of the genus Carcharhinus. The shark grows to a maximum length of 11.5 feet (3.5 metres), but is usually 7.3-7.8 feet (2.2-2.3 metres) long. It is found in tropical and subtropical coastal waters worldwide, as well as river systems and freshwater lakes.

This seemed to demonstrate that the shark's other senses weren't as developed as the sense of smell. Further research demonstrated that sharks actually have several acute senses, but that they depend on all of them working together. When you take one away, it significantly hinders the shark's hunting ability. The shark's nose is definitely one of its most impressive (and prominent) features. As the shark moves, water flows through two forward facing nostrils, positioned along the sides of the snout.

Unlike other species of shark, the bull shark is able to tolerate fresh water. As a result of this, it is not uncommon for bull sharks to be found in freshwater rivers and lakes. In recent years there have been a number of reported attacks by bull sharks in fresh water and also river mouths. Shark attacks on humans however are rare and often the result of mistaken identity. The onus is always on the individual to ensure his or her safety.

Sharks have 5 or more rows of teeth. Humans only have 20 baby teeth and 32 adult teeth. Sharks can re-grow teeth. Humans only get 2 sets (milk teeth and permanent teeth). Sharks have serrated edges on their teeth. Shark teeth are not attached to the jaw. Humans bite and chew with their teeth. Sharks use their teeth to rip their prey apart.

Answer: Sharks live in every ocean in the world, however studies published have shown that up to 70% of oceans are free of sharks. Sharks are not territorial like most animals are, so they change frequently their habitat.As many other fish, females do not stay to take care of eggs.ost species of sharks are found in the oceans. However, some of them are known to live in bodies of fresh water, like the bull shark which is known to travel up to 4,000 Km up the Amazon River.

Sharks fertilize the egg within the female body which is unique for a bony fish [4]. The male shark has a sex organ called claspers which transfers sperm into the female shark in order to fertilize eggs [4]. The embryo can spend up to two years developing inside the mother [4]. Sharks will sometimes give birth directly to baby sharks or release their eggs on the ocean bed [4].

The longest-living shark is the spiny dogfish, which can live from 75 to 100 years, while its cousin, the blue shark, only lives 15 to 16 years in the wild. Great white sharks live between 25 and 30 years. Tiger sharks live for an average of 27 years, but have been known to live to be 50. When sharks are taken into captivity, their lifespan can decrease up to 50 percent.

Myth 5: Sharks Can Detect a Single Drop of Blood in the Ocean! Sharks are often portrayed as having an almost supernatural sense of smell. However, reports that sharks can smell a single drop of blood in a vast ocean are greatly exaggerated. While some sharks can detect blood at one part per million, that hardly qualifies as the entire ocean. Sharks do, however, have an acute sense of smell and a sensitive olfactory system--much more so than humans.

Sharks and the dogfish Biologically, sharks are fish belonging to the phylum Chordata and the subphylum Vertebrata.

Sharks' eyes are built just like ours. In the late 1960s, researchers discovered that shark eyes have duplex retinas, or retinas containing both rod and cone cells. Rods enable the shark to see light and darkness, while cones allow for the detection of color (though scientists are still unsure how sharks interpret colors). The eye structure of a shark is similar to other vertebrates in that it contains a cornea, lens, retina, pupil and iris.

Despite what media and movies may lead us to believe, sharks are not man eaters out to get us. Rather, they are widely diverse with more than 350 species ranging greatly in size, habitats and diet. Shark attacks are few and far between with very few species involved. According to the International Shark Attack File, you are about 45,000 times more likely to be killed in a car accident than you are by a shark attack. Yet sharks often get a bad rap for simply behaving naturally in their native environment.

1 Jacques-Yves Cousteau says that it is: the only species of shark that is never frightened by the approach of a diver, and they are the most dangerous of all sharks..  Fastest The fastest swimming sharks are the mako sharks and blue sharks, which can even leap out of the water. They are also probably the fastest fish. Estimates of their speed varies; some say that they can swim at about 60 miles per hour (97 kph), while more conservative estimates are about 22 mph (35 kph).

The largest weight of a whale shark registered is 47,000 pounds or 21.5 tonnes. From there, weights are smaller and change according with the species. Male bull sharks weight around 200 pounds while female bull sharks can reach up to 290 pounds. The largest tiger shark captured weight was 1,450 pounds. The great white shark weight ranges from 1,500 lb. to 2,500 lb.

Offspring of this shark, sport reddish-brown spots on the tail and the posterior end of the body. These spots fade as they grow. The length of an average sand tiger shark can range between 1.2 to 2.7 meters, but the longest specimen had a body length of 3.2 meters. These sharks weigh between 90 to 160 kilograms. One of the distinguishing features of this shark, is that they are the only known sharks, that swim to the surface to take in air.

Shark and Ray Reproduction. Sharks have been around for a long time, making them evolutionarily successful. Over hundreds of millions of years of evolution, sharks have developed a wide range of reproductive adaptations, a characteristic which has allowed them to survive major extinction episodes.eproductive cycles for sharks can be as long as two years. For most sharks species, even the simplest descriptions of their reproductive cycles, including the ovarian cycle and gestation period, is lacking in detailed information.

The fins are added for their texture. Not all sharks are edible. Most commonly consumed shark varieties are dogfishes, catsharks, sand sharks, makos, and smoothhounds. Mako fish is a delicacy for their meat is salmon-coloured having a very fine quality. Mako liver is used to prepare oil that is rich in vitamins. The skin of the shark is made into leather and the fins are added to shark fin soup. However, the meat can be eaten with its nutrient value only when cooked properly.

The great white shark (Carcharodon carcharias), also known as the great white, white pointer, white shark, or white death, is a species of large lamniform shark which can be found in the coastal surface waters of all the major oceans.he great white shark has no natural predators other than the killer whale. The great white shark is arguably the world's largest known extant macropredatory fish, and is one of the primary predators of marine mammals.

Therefore, they are under enormous threat of extinction if humans are left to kill them indiscriminately. The Great White Shark and the Grey Nurse Shark are both examples of such species. The hunting or killing of sharks has a number of negative impacts, both direct and indirect. These include: 'sharks are predators. By killing off vast numbers of these marine hunters, the natural order of various other species, which are the natural prey of sharks, is disturbed. It affects the way that they interact with one another and affect the well-being and balance of other species.

Sharks usually attack on sight, but not always. If a shark keeps its distance, it is only curious. However, if it starts to circle inwards and begin sudden movements, then the likelihood of an attack is greatly increased.Shark attacks are rare, and the likelihood of a fatal attack is even rarer.he shark meat must be cooked before consumption in order to avoid contracting sickness. To cook the raw shark meat, the player must first hack at the shark until it yields the meat before dragging the pieces over a lit fire.

Hammerhead sharks can be found both in deep and shallow waters. Out of nine species, two are listed as endangered (great hammerhead and scalloped hammerhead) and one as vulnerable (golden hammerhead) species. People pose the greatest threat for the survival of the hammerhead sharks. They hunt hammerhead shark because of the fins that are served as delicacy in certain parts of the world. After the fins are removed, sharks are returned into the ocean. Sharks without fins cannot swim and they are dying in agony.

How Fast Can a Shark Swim? Sharks typically swim with the even, liquid grace of a creature completely at home with its place in the Universe. Large sharks generally cruise at a leisurely 1.5 miles (2.4 kilometres) per hour. Because most species fare poorly in captivity, the maximum swimming speed of a shark has seldom been measured. The Blue Shark (Prionace glauca) is an open ocean glider, planing on wing-like pectoral fins and flattened belly.

Sharks are related to skates and rays, and there are close to 400 species in the world. Along the Atlantic Coast, sharks generally migrate north in the spring and south in the fall.

Fox shark is the earliest known English name for this species and is rooted in classical antiquity, from a belief that it was especially cunning. In the mid-19th century, the name fox was mostly superseded by thresher, referencing the shark's flail-like use of its tail.t is also known by many other common names, including Atlantic thresher, grayfish, green thresher, long-tailed shark, sea ape, sea fox, slasher, swiveltail, thintail thresher, thrasher shark, and whiptail shark.

Meet the Whale Shark's Closest Relatives. WHALE SHARK. Whale sharks are members of the carpetshark family. Some carpetsharks are flat and live on the ocean floor. Some look more like snakes than sharks. Many are also just a foot long, yet the biggest fish in the world, the whale shark, is also a carpetshark. All carpetsharks have several features in common: two spineless dorsal fins, mouths in front of their eyes, and odd-looking sensory attachments called barbels that most often extend from their nostrils or jaws.

Researchers realized that they had seen goblin sharks before -- not swimming in the seas, but in fossil remains. Shark fossils from the Scapanorhynchus species dating back more than 100 million years bore striking resemblance to the goblin shark [source: Bright ].he last goblin shark sighting occurred in 2007 in Tokyo Bay, Japan [source: Mehta ]. After one day in captivity, the living fossil fish died. Since opportunities like that one are few and far between, it may be a long time before we decode all the mysteries of the goblin shark.

Across the U.S., there have been 1,022 attacks since 1670 and a total of 36 deaths. There has never been a fatal attack in Palm Beach County, where the sharks have been seen this week. Most shark attacks across the state occur in July, August, September and October. 'That's 1,000 sharks per square kilometer. If you were a swimmer, you would probably be within 60 feet of a shark.'. The most commonly spotted sharks are spinners and blacktips, but the team has also observed hammerheads, tigers, lemons and bulls.

MYTH: The Great White is a common shark found off beaches visited by humans. FACT: Great Whites are relatively uncommon large predators that prefer cooler waters. In some parts of their range, great whites are close to being endangered. MYTH: Whale sharks, the largest species of sharks, are voracious predators. FACT: Whale sharks, which are the largest fish that ever lived, are plankton feeders like the great whales, thus the name. A reef shark on the prowl is seldom a target for anglers.

According to the Shark Trust conservation organization, sharks hear sounds with frequencies ranging from 10 hertz to 800 hertz, and they are particularly responsive to sounds lower than 375 hertz. For comparison, 10 hertz is 1.5 octaves below the lowest note on a piano [source: PBS]. Humans, on the other hand, hear sounds ranging from 25 hertz to 16,000 hertz [source: Shark Trust]. Sharks can hear sounds much lower than we can, while we hear sounds much higher than sharks.

Goblin shark. The Goblin shark (Mitsukurina owstoni) is a rare, poorly-known species of deep-sea shark. Sometimes called a living fossil, it is the only living species in the family Mitsukurinidae. The Goblin shark can be easily identified by its long, flattened snout. Males can reach up to lengths of 12.6 feet (3.8 metres), and females can reach up to lengths of 12.2 feet (3.7 metres). The heaviest Goblin shark found weighed 210 kg (460 pounds).

Whale shark pups are about 2 feet long when born. Scientists are not sure how long whale sharks live, but based on their large size and their age at first reproduction (around 30 years old for males) it is thought that whale sharks may live at least 100-150 years.ne of the most notable facts about whale sharks is that they are the world's largest fish. At a maximum length of about 65 feet and weight of 75,000 pounds, a whale shark's size rivals that of large whales.

While people tend to imagine all sharks as being active hunters of other animals, in fact they occupy a huge range of ecological niches, from the huge, planktivorous Basking and Whale sharks to the bottom dwelling Carpet sharks, and probably the ultimate pelagic predator; the Great White shark.asking sharks and other filter feeders like the Whale shark suck water in through their mouths as they swim and purge it through their gill slits, filtering out the food in each mouthful, occupying a similar niche to the baleen whales and the Manta ray.

The great white shark (Carcharodon carcharias), also known as the great white, white pointer, white shark, or white death, is a species of large lamniform shark which can be found in the coastal surface waters of all the major oceans.his shark reaches its maturity around 15 years of age and was previously believed to have a life span of over 30 years. The true lifespan of great white sharks is far longer, now estimated to be as long as 70 years or more, making it one of the longest lived cartilaginous fish currently known.

Most people have little difficulty recognizing a shark when they see one. Yet sharks are an incredibly diverse group of fishes, and unifying them all under a single definition is not as simple as many imagine.Sharks are, of course, most famous (and infamous) for their teeth.What makes shark teeth special is that they are produced and shed serially, rotating forward as though riding on a kind of dental conveyer belt.ike most fishes, sharks have two sets of paired fins (pectoral and pelvic, corresponding to arms and legs in humans) but-unlike those of bony fishes they are supported by soft, unsegmented rays called  ceratotrichia  (used in making shark-fin soup).

The body of a tiger shark can be around 3-5 meters long which is about 9.8-16.4 feet long. Some can get even bigger than that, for instance one tiger shark was found to be 55 meters long which is about 18 feet long.As for weight, a tiger shark will usually weigh around 385-635kg which is about 849-1400 pounds.he body of a tiger shark can be around 3-5 meters long which is about 9.8-16.4 feet long.

The typical lifespan in the wild for Hammerhead Sharks is from 20 to 30 years approximately. Sandbar sharks or Brown sharks are considered to live between 20 and 30 years. Research made by Joung (2004) identified to be about 20 years of age.ome scientists believe that the life expectancy of the Great White Sharks is around 30 years (Levine, 1988) but other research indicates that they can reach up to 40 years. The lifespan of Tiger Sharks in the wild is believed to be 27 years in average, although some may live up to 50 years of age.

Whale sharks are slow swimmers and their top speed is no more than 5 miles (8 kilometers per hour) probably due to the fact that whale shark is the biggest fish in the world. It reaches a length of 40 ft (12 m) and weighs up to 13 tons (12 metric tons).Great white sharks are one of the fast movers in water.ormally sharks swim at a speed of less than 5 kph but few species such as mako sharks are able to cruise at a speed of 48 kph. Makos are the worldâs fastest swimmers.

  Yes, a large great white shark could kill an adult orca, and an orca could kill a large great white shark.   Most likely an orca would win most of the time but the sh â¦ ark has enough tools at its disposal to easily destroy an orca, it would come down to circumstance and chance.5 people found this useful.inutes later the killer whale surfaced, with the great white shark dead in its mouth. Flocks of gulls were feeding on pieces of the shark, whilst killer whales ate the sharks liver which had been torn from the carcass.

LEGENDS OF SHARK-MEN. Kamaikaahui lives at Muolea in Hana district of Maui. He was born in the form of a rat, then became a bunch of bananas, then a man with a shark's mouth at his back, over which he always wears a cloth to conceal the mark.He is a man on land and a shark in the sea.anaue is the shark-man of Waipio in the time of Umi, child of Ka-moho-aliâi and Kalei. His maternal grandfather feeds him meat, hoping to make a warrior of him, and he develops a taste for human flesh. When detected at Waipio he turns into a shark and swims to Hana, where he marries the sister of a petty chief.

Taxonomy refers to the official classifications of plants or animals according to accepted scientific standards and norms. As a group, sharks belong to the superorder called Selachimorpha. They are in the Chondrichthyes class (along with Chimaeras) under the subclass Elasmobranchii.This subclass is also where rays and skates fall and some sharks are thought to be very closely related to certain ray species (even more so than to other sharks, in fact). Selachimorpha is split into Galea and Squalea.The Galea group comprises:his subclass is also where rays and skates fall and some sharks are thought to be very closely related to certain ray species (even more so than to other sharks, in fact).

In the last three years, the number of shark attacks in Hawaii has tripled compared to the number of attacks 10 to 15 years ago, according to a comprehensive list of shark incidents maintained by the DLNR. And, since 2012, more than 60 percent of all shark attacks in the Aloha State occurred just off Maui. All fatal shark attacks in the last 20 years in Hawaii have occurred near Maui, and three of those happened in the last three years. The most recent attack was in April. A 65-year-old woman was killed by what is presumed to have been a tiger shark as she was swimming off Makena. The incident made headlines worldwide.

Shark attacks are extremely rare. An individual is three times more likely to be hit by lightning than to be bitten by a shark. There were an average of 32 shark attacks per year in U.S. waters between 1990 and 2004. Of the 490 attacks during this 15-year span, 11 were fatal.Most people die in the deep waters, some on the shores.n individual is three times more likely to be hit by lightning than to be bitten by a shark.

While longevity data are not available for many sharks, maximum ages do vary by species. Some sharks like the smooth dogfish (Mustelus canis) may only live 16 years, while others such as the porbeagle shark, (Lamna nasus) may live as long as 46 years.Whale sharks (Rhincodon typus) the largest fish in the world may live over 100 years.here is no accurate data available about how long a Bull Shark can live to. However, they are known to live to ages of around 15 to 20 years. They reach full size and sexual â¦ maturity at around the age of 10. Since they are elusive creatures that havent been studied extensively, not much is known about them.

Swai Fish. The Swai Fish, or Iridescent Shark, is a rather unremarkable fish that is typically farmed in Asia. However, it seems to create a bit of controversy in what contexts it appears. Whether it is to be kept in an aquarium or to be eaten at the dinner table, the Swai Fish has opposing viewpoints. The Iridescent Shark is not really a shark but gets its name because it resembles on in appearance. It can be found on the market as Swai Fish and shark catfish. It is a member of the catfish family. As a juvenile, the Swai Fish radiates a glow from the edges of its fins, thus given the name Iridescent Shark. It can grow up to four feet in length and weigh up to nearly 100 pounds.

The Bull shark (Carcharhinus leucas), or Zambezi shark, is a species of shark of the genus Carcharhinus.

1 Both sharks and bony fish have caudal fins, or tail fins with two lobes. 2  The caudal fin of a shark is considered heterocercal, meaning the two lobes are unequal in size and the vertebral column extends up into the top lobe. The skull of a shark is made of only 10 cartilaginous elements while a bony fish skull has about 63 bones. 2  Bony fish have pleural ribs formed from dermal bone and sharks lack these ribs. 3  Unlike bony fish that have a protective bony plate covering their vulnerable gills, the gill slits of a shark are exposed and visible.

Ideas (Killer whales) hunt and kill sharks in groups but they â¦ can kill sharks alone without getting insured or killed. Orcas are self-trained on how to kill sharks. Killer whales are extremely intelligent ocean predators and can flip sharks upside down causing tonic immobility.iller whales (orcas) are at the top of the food chain and are known to eat sharks. They also eat other marine mamm â¦ als such as seals, sea lions, walruses and even smaller whales. They also feed on birds, sea turtles, penguins, polar bears, reptiles, octopus and even land mammals.

The outer design of sharks and bony fish is also contrasting. 1  Shark skin is covered by dermal denticles, toothlike placoid scales that are covered with enamel. 2  Shark fins are stiff and lack the fine bony spines and muscle control found in teleost. 3  Both sharks and bony fish have caudal fins, or tail fins with two lobes. Bony fish are covered in flat scales, either cycloid, ctenoid or ganoid, that grow as the fish grows. 2  The rings on these scales can be used to estimate age in bony fish, just as you would count the rings on a tree. 3  However, dermal denticles do not grow with the shark so they can not be used in age estimation.

The whale shark (Rhincodon typus) is a slow-moving filter feeding shark and the largest known extant fish species. The largest confirmed individual had a length of 12.65 m (41.50 ft) and a weight of approximately 21.5 metric tons (47,000 lb), and unconfirmed reports of considerably larger whale sharks exist.hale sharks have a mouth that can be 1.5 m (4.9 ft) wide, containing 300 to 350 rows of tiny teeth and 10 filter pads which it uses to filter feed. Whale sharks have five large pairs of gills. The head is wide and flat with two small eyes at the front.

The cartilage used in supplements usually comes from either sharks or cows, called bovine cartilage. Shark cartilage was proposed as a treatment for cancer, based on the false idea that sharks do not get cancer (they do).In test tubes, cartilage seemed to stop new blood vessels from forming. Cancerous tumors need new blood vessels to keep growing, so researchers wondered if shark cartilage could shrink tumors.artilage is sometimes suggested for the following health conditions: Psoriasis. Preliminary studies suggest that extracts of shark cartilage may reduce inflammation and itching from psoriasis. Psoriasis is a skin disorder that shows up as raised, reddish-pink areas covered with silvery scales and red borders.

Biologist Mauricio Hoyos Padilla posted a Facebook video of what he claims is the biggest great white shark ever filmed: An approximately 20-foot (6-meter) long female dubbed Deep Blue. According to the California Department of Fish and Game, great white sharks can grow up to 21 feet (6 meters) long. However, most great whites are around 12 to 14 feet (3.6 to 4 meters) long, says Christopher Lowe, a shark biologist at California State University in Long Beach. A 17.9-foot-long (5.5-meter-long) male great white was caught off Guadalupe in fall 2009. (Related: Biggest Great White Shark Caught, Released.) Deep Blue is clearly a very large shark, he says.

The amount of food that a shark eats each day depends on the type of shark it is. Some Shark species will eat huge meals and then not eat again for weeks. They can survive on the oil that is stored in the liver when they do eat. When that gets low, they will have the instinct to eat again.

You may wonder why this fish is called a whale shark. Scientists have determined that it is a species of shark, because of its skeleton (composed entirely of cartilage), and its tough, leathery, scaleless skin. People called it a whale shark because of its enormous size (like a whale), not because it's a type of whale.

Probably the best known species of shark is the great white. This is believed to be the most dangerous type of shark in the world. People have been able to see them as they are among the rare species that do raise their heads out of the water. Great white sharks can grow up to 16 feet and weight around 1,500-2,400 pounds.

The type of shark they are asking for is clearly a Great White  Shark.   It's alot faster than 1 mph, a human swims 2-5 mph average.

A shark tooth contains resistant calcium phosphate materials.[1] Sharks continually shed their teeth; some Carcharhiniformes shed approximately 35,000 teeth in a lifetime, replacing those that fall out.[2] There are four basic types of shark teeth: dense flattened, needle-like, pointed lower with triangular upper, and non-functional.

Shark teeth are the most common type of fossil for a number of reasons. First, shark teeth, like most teeth, are made of dentin, a hard calcified tissue that does not easily decompose. Dentin is harder and denser than bone. In a tooth, the Dentin is surrounded by a very hard enamel shell. Secondly, to maintain a sharp smile, shark teeth are designed to regularly fall out and be replaced.

The coloration of sharks is enormously unique and important; not only is it yet another form of protection from their predators, but it also aids them when capturing prey. The dorsal (top) side of a shark is a lighter color than the ventral (bottom) side. This coloration is a type of camouflage called counter shading. When viewed from above, the dark side of the shark blends in with the depths of the ocean. When viewed from below, the light ventral side blends in with the oceanâs surface.

Whales sing haunting songs, dolphins yap and click, snapping shrimps crackle like castanets, and teleost fishes produce all sorts of grumbles, burbles, grunts, croaks, buzzes, and clicks. But, although they are very much attuned to this great oceanic opera, sharks are  by and large the quintessential silent hunters. Unlike their noisy neighbors, sharks have no organs for producing sound. Even their scales are modified to allow them to slip through the water in ghost-like silence. But there are persistent reports from New Zealand of a type of shark that actually barks like a large dog.

The targeted shark-fin fisheries around the world are trading the fins of between 26 to 73 million sharks every year (according to a 2006 estimate) with a worth of $400-550 million. Driving this trade is the demand for and consumption of shark fin soup in Asia.

The Whitetip Reef Shark is also known as the Triaenodon Obesus. Along with the Blacktip Reef Shark and Gray Reef Shark, it is one of the most frequent sharks in the Indo-Pacific. This species is easily spotted due to its curious, irregular, and waving swimming style and of course, the white tip on its dorsal fin.

Sharks have lived in the seas for at least 300 million years. Before there were any dinosaurs roaming the Earth, there were sharks. Today, sharks inhabit all of the world's oceans at all latitudes and ocean temperatures. Some live in shallow water, while others live in water so deep that the sun never reaches them. No matter where you go, there are sharks to be found.

These sharks can raise their temperature about thâ¦e temperature of the water; they need to have occasional short bursts of speed in hunting Cold blooded although if you've ever seen a Great White Shark hunt sea lions you'd be thinking they would have to be hotblooded. Actually the Salmon Shark is a warm blooded shark.

Hammerhead shark. The hammerhead sharks are a group of sharks in the family Sphyrnidae, so named for the unusual and distinctive structure of their heads, which are flattened and laterally extended into a hammer shape called a cephalofoil. Most hammerhead species are placed in the genus Sphyrna while the winghead shark is placed in its own genus, Eusphyra.

Rarely-spotted megamouth shark washes up on Philippine beach. 1  The 15-foot shark was found dead on the beach in Marigondon, Pio Duran. 2  It's only the 66th megamouth shark ever seen, according to experts. 3  Nicknamed 'Toothless', the shark was preserved in ice by local villagers.

New Smyrna Beach is the most common place to encounter sharks not only in the United States but in the world, Burgess said. With nearly 300 total shark attacks from 2004 to 2013, Florida tops the charts for the place with the highest shark activity, according to data from the International Shark Attack File.

The number of teeth a shark has depends on the species of shark. For example, the great white shark has about 50 teeth in its mouth. But the amazing thing about sharks is that they can replace damaged and lost teeth very easily. Below the teeth they have in their mouths, there are several rows of new teeth waiting to replace the old ones.

In California, bites from sharks (particularly great white sharks) have been estimated to cause 10% of sea otter deaths and are one of the reasons the population has not expanded further north. The great white shark is believed to be their primary predator, and dead sea otters have been found with injuries from shark bites.

Another early shark that may have given rise to modern sharks is Mcmurdodus, which had an even earlier start of 390 million years ago. Most of the early sharks of this period were near-shore predators. By the mid-Cretaceous, about 100 million years ago, many sharks had evolved into fast-swimming, off-shore predators.

The term shark attack is used to describe an attack on a human by a shark. Every year over 70 attacks are reported worldwide. Despite their relative rarity, many people fear shark attacks after occasional serial attacks, such as the Jersey Shore shark attacks of 1916, and horror fiction and films such as the Jaws series.

Whale Shark Populations in the Gulf of Mexico. A whale shark swimming and feeding at surface during a June 2010 feeding aggregation at Ewing Bank. Photograph by Eric Hoffmayer. About the Project. The Gulf of Mexico is an essential habitat for many shark and ray species, including the whale shark (Rhincodon typus).

1 The whale shark has a huge mouth which can reach up to 4 feet (1.4 m) across located at the front of the head.  The skin of a whale shark can be as thick as 4 inches (10 cm), which limits possible predators to killer whales, great white sharks, tiger sharks and humans.

Natural History. The sandbar shark is one of the largest coastal pelagic sharks, and can be eight feet long. True to its name, it's often found in sandy or muddy areas close to land. Also known as the brown or thickskin shark, the sandbar shark is easily recognized by its large dorsal (top) fin.

Diving with Sand Tiger Sharks. Ragged tooth sharks, also known as Sand tiger sharks, Grey nurse sharks or just Raggies, has a unique hunting strategy. It is able to gulp air from above the surface and collect the air in its stomach. This enables them to become buoyant and approach their prey virtually motionless.

After fisheries catch sharks, they often strip off the high-value fins and toss the rest of the shark overboard. The process is called finning. Often, the shark is still alive and lies helpless on the seafloor until it dies. Worldwide trade in shark fins increased from 3,300 tons in 1980 to 12,900 tons in 2000.

A look at sharks found off Delaware. Sharks found in our waters. Delaware's beaches are relatively safe even though sharks are so common. The Delaware Bay estuary deposits sand along the beaches, making the coastal bottom shallow. Sharks hunting for fish in the deeper waters are far away from swimming areas.

Sharks can be spotted in areas as shallow as 20 feet of water in search of seals. Beaches of Brevard County, Florida. Has 90 shark confrontations on file that took place over the past 100 years with most of the attacks afflicted by Bull Sharks, Hammer Heads and Black Tip sharks.

Why Do We Care What Sharks Eat? Sharks are an important part of the food chain. A food chain shows how animals, like sharks, get the food needed to live and what they usually eat. Sharks are important to the food chain because they eat weak or sick animals. This keeps the animal population where they live healthy.

1 The second biggest fish and shark is the basking shark (Cetorhinus maximus) which is about 40 feet (12.3 m) long and is another filter feeder.  The biggest meat-eating shark is the Great white shark (Carcharodon carcharias) which grows to be up to 21 feet (6.4 m) long.

Despite this, the nurse shark is a solitary hunter and will spend the dark nights hunting alone. Nurse sharks appear to have resting spots that they return to daily rather than just resting anywhere. These preferred resting spots of the nurse shark tend to be in crevices in rocks and reefs. The nurse shark mating season is in early summer.

Some of the most common predators are dusky shark, great white shark, tiger shark, and bull shark. Mostly the calves fall victim to these enemies. Another reason as to why these species are becoming endangered is that dolphins also suffer from parasites and diseases. Some of these species are really declining in numbers such as Amazon river dolphin, Yangtze river dolphin, and Ganges.

The family Lamnidae also includes the great white shark and the porbeagle. Mako sharks are capable of swimming at speeds up to 60 km/h (37 mph), and jumping up to 7 m (23 ft) into the air. The great white shark is also closely related to an ancient mako shark, Isurus hastalis.

Mako shark. Mako shark (genus Isurus), any of two species of swift, active, potentially dangerous sharks of the mackerel shark family, Isuridae. The shortfin mako (Isurus oxyrinchus) is found in all tropical and temperate seas, and the longfin mako (I. paucus) is scattered worldwide in tropical seas.

The tiger markings that are typical of younger tiger sharks may be a way to blend in with the waves near the coast, so that larger predators don't find them. Baby tiger sharks better watch out -- larger tiger sharks have been known to eat them! Read on to find out all the other zany things that tiger sharks eat.

This shark is a solitary, mostly night-time hunter. Its name derives from the dark stripes down its body, which fade as the shark matures. The tiger shark is a predator, known for eating a wide range of animals. Its usual diet consists of fish, seals, birds, smaller sharks, squid, turtles, and dolphins.

Most species of sharks are found in the oceans. However, some of them are known to live in bodies of fresh water, like the bull shark which is known to travel up to 4,000 Km up the Amazon River.ost species of sharks are found in the oceans.

I love sharks and find them fascinating, so I was surprised to learn that many of them have very long pregnancies. In fact, 2 years is not at all uncommon in the shark kingdom. However, one shark in particular takes the award for the most insane pregnancy span in all the world. The Frilled Shark, once pregnant, will remain so for about 3-AND-A-HALF YEARS! I am speechless. I am blown away.

C Length 8 in.-40 ft. Sharks have been around for over hundreds of millions of years. While many of us may be familiar with a few shark species, there are over 400 of them, from the 8-inch-long dwarf lanternshark to the 40-foot-long whale shark. Sharks are efficient predators with a highly developed sense of smell, hearing and sight.

Finally, like most sharks, the sawshark has its gill openings on the sides while the ray has them on its underside. 5. Cookiecutter shark.

1. Shark teeth are not attached to gums on a root like our teeth. 2. Sharks typically lose at least one tooth per week. 3. Sharks lose their teeth because they may become stuck in prey or broken and forced out. 4. Shark teeth are arranged in neat conveyor belt rows and can be replaced within a day of losing one. 5.

This is a list of recorded fatal shark attacks in South African territorial waters in reverse chronological order. It includes: shark attacks that were fatal and the body was later recovered, shark attacks that were fatal immediately or almost immediately fatal, and shark attacks that the victim died later due to the injuries of the attack.

The typical lifespan in the wild for Hammerhead Sharks is from 20 to 30 years approximately. Sandbar sharks or Brown sharks are considered to live between 20 and 30 years. Research made by Joung (2004) identified this to be about 20 years, while Sminkey (1996) mention that sandbar sharks can live more than 30 years.

Whale shark. (Redirected from Whale sharks) The whale shark (Rhincodon typus) is a slow-moving filter-feeding carpet shark and the largest known extant fish species. The largest confirmed individual had a length of 12.65 m (41.5 ft) and a weight of about 21.5 t (47,000 lb).

Wes Pratt, Mote Center for Shark Research. Nurse sharks are easily identified by the small mouth located forward of the eyes and just under the broad snout. The mouth is bracketed by two sensory barbels. Most nurse sharks range in color from light to dark brown, though rare albino nurse sharks also exist.

Making the world better, one answer at a time. Yes, there is a variety of sharks in the Delaware Bay. Sand Tiger and Brown sharks are common and are often about 4-6 feet long.

The shark fins provide texture, while the taste comes from the other soup ingredients.

How long does it take for a salt water shark egg to hatch?   Well, the length of time for an egg to hatch depends on the species of shark. At my aquarium store, we had a banded shark egg hatch after four months and four days in ou â¦ r store. I have no experience with marbled cat shark eggs.

Evidence of How Long Sharks Have Been Around. Sharks have lived in the Earth's oceans for as many as 450 million years -- long before dinosaurs roamed on land. These ancient creatures have adapted to survive five mass extinctions. The earliest sharks probably didn't look much like modern sharks, and they stayed close to shore in search of prey.

The rest of the shark is a velvety black color. The Black shark is completely black and velvety. Albino versions of these sharks are rare but do exist and follow the same care needs as fish of the standard coloration. These sharks can attain sizes as long as six inches and live for eight to ten years in optimal conditions.

The gestation period for a great white shark is about 18 months. This limits how much a great white shark is able to reproduce which can cause problems with human fishing taking so many great white sharks out of our oceans every year. Fortunately, the great white shark is able to give life birth to between four and six pups.

1 It is also the biggest fish. The second biggest fish and shark is the basking shark (Cetorhinus maximus) which is about 40 feet (12.3 m) long and is another filter feeder.  The biggest meat-eating shark is the Great white shark (Carcharodon carcharias) which grows to be up to 21 feet (6.4 m) long.

Sharks are some of the most frequently studied cartilaginous fish. 1  Sharks are distinguished by such features as: 2  The number of gill slits. 3  The numbers and types of fins. 4  The type of teeth. 5  Body shape. 6  Their activity at night. 7  An elongated, toothed snout used for slashing the fish that they eat, as seen in sawsharks.

How fast can a tiger shark swim? Tiger sharks have a maximum speed of about 32 km per hour, which equates to around 20 miles per hour. How fast can a hammerhead shark swim? 8 kilometres per hour (5.0 mph) but when feeding or attacking, the average shark can reach speeds upwards of 19 kilometres per hour (12 mph).

These stop the backflow of water as the whale shark closes its mouth, preventing the loss of food. The skin of an adult whale shark can be as thick as 4 inches (10 cm) and has the consistency of strong rubber, which limits possible predators to killer whales, great white sharks, tiger sharks and humans.

They can reach 3 to 20 feet in length and up to 1000 pounds in weight. 2  Hammerhead sharks have white bellies and olive green or grey-brownish back. 3  Mouth of hammerhead sharks is located on the underside of the head.

Salmon Shark Facts (Lamna ditropis) Salmon sharks (Lamna ditropis) are large, powerful, warm-bodied (endothermic), and streamlined predators adapted for high-speed swimming. Reports from the U.S. Navy have clocked salmon sharks exceeding 50 knots. This would make the salmon shark one of the fastest fish in the ocean.

The Fastest Sharks. Not all sharks move around at super speed, but a few varieties have shown a talent for cruising through the water like torpedoes. Mako sharks and blue sharks, for example, are estimated to hit speeds between 22 and 46 miles per hour as they chase prey or move from one location to another. For comparison, the fastest human swimmer clocks in at about 5 miles per hour.

The shortfin mako is the fastest shark in the ocean, able to reach a top speed of 31 miles per hour. This shark is also capable of breaching the ocean surface to capture prey, reaching heights of up to 20 feet. The slowest shark in the ocean is the Greenland shark, able to reach a top speed of 1.7 miles per hour.

Dogfish come in all shapes, sizes, and colors and they live in almost every ocean habitat and depth.ogfish sharks are an excellent example of the exciting biodiversity that can be found among sharks! Photo Gallery. With over 100 species, Dogfish literally come in all shapes and sizes.

Full Answer. The longest-living shark is the spiny dogfish, which can live from 75 to 100 years, while its cousin, the blue shark, only lives 15 to 16 years in the wild. Great white sharks live between 25 and 30 years. Tiger sharks live for an average of 27 years, but have been known to live to be 50.

The typical lifespan in the wild for Hammerhead Sharks is from 20 to 30 years approximately. Sandbar sharks or Brown sharks are considered to live between 20 and 30 years. Research made by Joung (2004) identified to be about 20 years of age. While, Sminkey (1996) mention that sandbar sharks can live to be more than 30 years old.

There are four main categories of restrictions, as follows: 1  Shark sanctuary (an area where shark fishing is entirely prohibited); 2  Areas where sharks must be landed with fins attached; 3  Areas where fin to body mass ratio-based regulations have been implemented; 4  Areas where shark product trade regulations exist.

Some live a bit shorter, and some live a bit longer. Male Whale Sharks can't breed until they are 30 years old. Whale Sharks live almost 70 years longer than people, so imagine you're a seventy-five year-old whale shark, an average whale shark would live another of those seventy-five years.

The Northern River Shark, unlike the Ganges Shark does not spend its whole life in freshwater. Instead they live in rivers, and the brackish water of both estuaries and bays. The Northern River Shark, is the largest freshwater shark, and grows to 8.2-9.8 feet (2.5-3m) in length. It has steel blue and white coloring, a flat head, and small eyes.

It is therefore not too difficult to see which species poses the greater threat to the other. After 400 million years of shark evolution, we could potentially wipe out the world's sharks in a century's time. The fact remains, however, that sharks can, and do, result in human deaths. Dogs and even traditionally mild-mannered animals like cows may kill people too, but the nature of shark attacks seems to fascinate and terrify us more.

Juveniles are subject to predation by larger fishes and sharks. One juvenile was found in the stomach of a blue shark and another in the stomach of a blue marlin. Orcas have also been mentioned as predators of juvenile whale sharks. By far, the most serious threat to this species is from humans. The meat of the whale shark is considered a delicacy in Taiwan. It is marketed fresh, salted, and smoked and sells for very high prices.

Some recreational shark fishermen do practice catch and kill techniques just for fishing records or to obtain jaws or mounts as trophies. Despite the fact that most sport fishermen are responsible stewards of the sea, some fishermen do heavily target sharks and may have a significant impact on some species, such as bull sharks (Casey and Hoey 1985) and blue sharks (Campana et al. 2006).

The triangular dorsal fin atop the shark helps the shark with balance. Most species have two dorsal fins but some only have one. The tail fin of sharks is called the caudal fin is considered heterocercal, meaning the top and bottom lobes are not symmetrical and the vertebral column extends upwards into the top lobe. Sharks move their caudal fins side to side to propel themselves forward.

Shark tournament. There has been a lot of attention placed on the impact of commercial fishing on shark populations, which is well warranted considering the sheer scale of the catches. However, the overall impact of recreational fishing on shark populations is not well studied and is typically difficult to detect. Recreational fishing for sharks is popular in many places like the United States, Australia, New Zealand, and the United Kingdom (Babcock 2008).

Sharks have long held a special awe and fascination for humans, possibly something to do with their unmatched ability as predators and their position at the top of the ocean food chain.asking sharks and other filter feeders like the Whale shark suck water in through their mouths as they swim and purge it through their gill slits, filtering out the food in each mouthful, occupying a similar niche to the baleen whales and the Manta ray.

According to the International Union for the Conservation of Nature Shark Specialist Group, 28 percent of shark species are at risk of extinction. An estimated 100 million sharks are killed annually, Worm and other researchers estimate, 20 million or more per every fatal shark attack. And that wholesale slaughter could already be sending dire consequences cascading down the food chain, much to the bane of scallop and lobster lovers.

In the Hawaiian Islands, since 1828, there have been 116 confirmed shark attacks and only 8 confirmed shark attack fatalities. For Hawaii, that averages out to a shark attack every 1.59 years, and a fatality approximately every 23 years. (Stats from Florida Museum of Natural History) You may say, but shark attacks are increasing each decade!. This is true because there are a lot more people in the World and a lot more people in the water.

Shark Week is an annual, week-long TV programming block created by Tom Golden at the Discovery Channel, which features shark-based programming. Shark Week originally premiered on July 17, 1988. Featured annually, in July and/or early August, it was originally devoted to conservation efforts and correcting misconceptions about sharks. Over time, it grew in popularity and became a hit on the Discovery Channel.

How Fast can Sharks Swim? Whale sharks are slow swimmers and their top speed is no more than 5 miles (8 kilometers per hour) probably due to the fact that whale shark is the biggest fish in the world. It reaches a length of 40 ft (12 m) and weighs up to 13 tons (12 metric tons). Great white sharks are one of the fast movers in water.

Overview â The distinctive tiger shark lives in both coastal and open seawaters, usually from the surface to around 459 feet. Young members of this species sport black stripes arranged over their otherwise gray backs and sides. These stripes can fade as the shark ages, making it look more like a great white than a tiger shark. Somehow it seems appropriate that this nocturnal, aggressive shark prefers dark, murky waters.

The International Union for Conservation of Nature has assessed the blacktip reef shark as Near Threatened.

SHARKOPEDIA: THE TOP 10 LARGEST SHARKS. Counting down the 10 largest sharks is a tricky endeavour. Beyond the two largest shark species of which we know, there is no consensus on how to rank the largest living ones. New measurements continue to be reported, and experts continue to squabble over which to accept and which to toss back. But until everyone's certain, here's our humble list of the worldâs top 10 largest shark species.

Just the thought of sharks still induces a primeval fear in many people, but of those fortunate enough to see live sharks in their own element, most cannot help but have a feeling of admiration for their beauty of movement and their supreme efficiency as predators.asking sharks and other filter feeders like the Whale shark suck water in through their mouths as they swim and purge it through their gill slits, filtering out the food in each mouthful, occupying a similar niche to the baleen whales and the Manta ray.

A female great white shark has completed the first documented round-trip ocean crossing by a shark, swimming farther than any other known shark, according to a new study. Nicole, as the shark is being called, traveled from Africa to Australia and backa total of 12,400 miles (more than 20,000 kilometers)in nine months. The feat also set a second record: fastest return migration of any known marine animal. Printer Friendly.

Most hammerhead species are placed in the genus Sphyrna while the winghead shark is placed in its own genus, Eusphyra. Many not necessarily mutually exclusive functions have been proposed for the cephalofoil, including sensory reception, maneuvering, and prey manipulation.ammerhead sharks are known to eat a large range of prey including fish, squid, octopus, crustaceans, and other sharks. Stingrays are a particular favorite. These sharks are often found swimming along the bottom of the ocean, stalking their prey.

Best Answer: The sharks body chemistry is designed to live in salt water. The concentration of salt on the inside of their cells matches the concentration of the water they live in. If you moved a shark to fresh water they would die. Water will always move through a membrane (like skin or a cell membrane) in order to make the concentrations on both sides match. So, it the concentration is lower outside the shark water will be pulled in the sharks cells to try to dilute them.

What are some of the different animals that make light? Although bioluminescence may be considered rare as measured by the total number of species, it is extremely diverse in its occurrence. There are many different types of organisms that produce bioluminescence, from microscopic cells to fish and even a few sharks. But there are no luminescent animals in higher vertebrates above the fish. Overall, luminescent organisms represent most of the major phyla.

by Caty Fairclough Sharks have been feared hunters ever since people first observed them swimming in the vast ocean. Yet today, sharks are declining rapidly on a global scale because humans have replaced them as the ocean\'s top predators. One way that humans hunt sharks is by using a practice called shark finning. This is the process of slicing off a sharkâs fin and discarding the rest of the still-living body, often by dumping it back into the ocean.

A power saw made out of shark teeth, for science. Researchers have combined the teeth of various sharks into what they are calling the Jawzall, a power saw for tearing fish flesh.by Michelle Starr @riding_red /.atherine Corn. What they found was that the tiger shark's teeth are the most deadly of those tested, breaking the salmon's spine in six cuts; the tiger shark often feasts on difficult prey, such as sea turtles and crustaceans, so deadly teeth are a requirement.

Best Answer: Leopard, soupfin, and blacktip are probably the most common sharks to be harvested for food. I would say that the leopard and the nurse sharks are probably the best tasting based on diet and location. I haven't had thresher or mako or any of the larger species. The best are sharks in their middle years of life. The older sharks are too tough and tend to have tighter, harder meat. The younger ones have little to no meat, and although tender enough, they don't offer much.

Sharks typically swim with the even, liquid grace of a creature completely at home with its place in the Universe. Large sharks generally cruise at a leisurely 1.5 miles (2.4 kilometres) per hour. Because most species fare poorly in captivity, the maximum swimming speed of a shark has seldom been measured. The Blue Shark (Prionace glauca) is an open ocean glider, planing on wing-like pectoral fins and flattened belly.

While some species inhabit shallow, coastal regions, others live in deep waters, on the ocean floor and in the open ocean. Some species, like the bull shark, are even known to swim in salt, fresh and brackish waters. Most sharks are especially active in the evening and night when they hunt. Some sharks migrate over great distances to feed and breed. This can take them over entire ocean basins. While some shark species are solitary, others display social behavior at various levels.

Shark bites occur more frequently in murky water. They are attracted by lights, noise, or splashing, and smell. For theses reasons surface swimming should be kept to a minimum, in shark waters. Research shows that bright colors attract sharks more than dark objects, so it is better for divers to wear dark colors. Blood in the water can attract sharks from long distances. They can sense blood in the water in concentrations as little as 4 parts per million.

Sharks do not normally hunt humans. When they do attack a human, it is usually a case of mistaken identity. Shark sometimes mistake humans for its natural prey, such as fish or a marine mammal or sea turtle, and most often will release the person after the first bite. The majority of shark bites are hit-and-run attacks by smaller species, such as blacktip and spinner sharks. They mistake thrashing arms or dangling feet as prey, dart in, bite, and let go when they realize it's not a fish.

The fish wind up in conservation limbo, since insufficient data is available. Such sharks include the thresher, Java, kitefin, salmon, broadnose sevengill, bigeye sand tiger, narrowmouth catshark, great hammerhead, Argentine angel shark and megamouth, which was only first discovered in 1976.re sharks dangerous or endangered? The answer is both. On the danger side, most sharks are apex predators. This means they exist at the top of the oceanic food chain and possess few, or no, natural enemies.

Many frilled sharks are found with the tips of their tails missing, probably from predatory attacks by other shark species. Parasites identified from this shark include a tapeworm in the genus Monorygma, the fluke Otodistomum veliporum, and the nematode Mooleptus rabuka.he gestation period may be as long as three and a half years, the longest of any vertebrate. Litter sizes vary from two to fifteen, and there is no distinct breeding season. Frilled sharks are occasional bycatch in commercial fisheries, but have little economic value.
