Great White Shark

The oceans hold about 96% of the entire water supply for the earth. However, different areas possess different characteristics.Therefore, some areas are densely populated by marine plants and animals, while others are less so. Sharks tend to prefer the shallower continental shelf areas. This is because these are the areas at which rivers deposit nutrients into the oceans.
Some Facts about sharks
Most species of shark eat things like fish, crustaceans, mollusks, plankton, krill, marine mammals and other sharks. Sharks also have a very acute sense of smell that allows them to detect blood in the water from miles away.Population.All sharks are carnivores, which means that they feed on other animals as opposed to vegetation. Most sharks survive off living flesh, while some may eat carrion, which is made up of the remains of fish and other marine animals that have already died. Sharks are usually thought of as having huge, razor-sharp teeth, just waiting to tear through the flesh of hapless prey. In the cases of some aggressive and large sharks, this may be true. However, sharks and their teeth are designed for varied diets. The Whale Shark, for example, feeds on plankton and small bony fish. For this reason, its teeth are largely undeveloped, and the catching of such prey is performed via sieves in its mouth.
In general, sharks will eat fish, other sharks, squid, mollusks, crustaceans, turtles, dolphins, porpoises, rays and seals, among other animals. The key ingredient in their prey needs to be fat, as this provides them with energy for travelling, hunting and maintaining an optimal body temperature.Sharks tend to stick to one type of prey, and their hunting technique and teeth are usually designed to suit this type of eating plan.
Great whites are found mostly along the coasts of Australia, South Africa, California and the northeastern United States. They are also found in fewer numbers around the Azores, Brazil, the Caribbean, northwestern Africa, eastern Africa, the Seychelles, Madagascar, Mauritius, Sri Lanka, northern Australia, New Caledonia, the Philippines and Hawaii. They prefer warm, salty, temperate coastal seas. The great white can swim not only on the surface, but also more than 820 feet (250 m) deep.Great whites are considered social creatures that travel in a group called a school or a shoal. When one great white wants to take the other's prey, both sharks will display various slapping demonstrations to discourage each other. They try to avoid fighting because just one bite may disable the shark permanently.
