Great white shark

Great white shark
Great white shark is a shark that has 300 teethes . It is a carnivore & eat seals.He never stops swimming  It can crush  his prey.

Distribution and habitat

The great white is an epipelagic fish, observed mostly in the presence of rich game, such as fur seals, sea lions, cetaceans, other sharks, and large bony fish species. In the open ocean, it has been recorded at depths as great as 1,200 m (3,900 ft). These findings challenge the traditional notion about the great white as being a coastal species.

Anatomy and appearance

Great white sharks, like many other sharks, have rows of serrated teeth behind the main ones, ready to replace any that break off. When the shark bites, it shakes its head side-to-side, helping the teeth saw off large chunks of flesh.

Adaptations

To more successfully hunt fast and agile prey such as sea lions, the great white has adapted to maintain a body temperature warmer than the surrounding water. One of these adaptations is a "rete mirabile" (Latin for "wonderful net"). This close web-like structure of veins and arteries, located along each lateral side of the shark, conserves heat by warming the cooler arterial blood with the venous blood that has been warmed by the working muscles. This keeps certain parts of the body (particularly the stomach) at temperatures up to 14 °C (25 °F)

SAVE ANIMALS

—It's super-easy to help animals, no matter how old you are. Check out how Save Animals to get a jump-start on making a huge difference in the lives of animal everywhere: Animals are alive for their own reasons, not to entertain us. Animals in movies, circuses, and zoos are denied everything that is natural and important to them. They will never be allowed to hang out with their families, graze, or do anything that they would do in the wild. Refuse to support this cruelty by never going to a zoo, marine park, or circus that uses animals. If your class is planning on dissecting any animal, ask your teacher for a humane alternative assignment, such as using a computer program to perform a virtual dissection. An animal will be saved, and you will actually learn and remember way more! Check out more info on how to get a dissection alternative at your school.
