Distribution and Habitat
The distribution of the great white is vast. They have been identified in nearly all temperate marine waters of the world with the highest density in regions with seal and sea lion populations. Great whites are mainly coastal and offshore, as opposed to oceanic.
In the Northern hemisphere, great whites have been identified in unlikely locations such as the Mediterranean, Red Sea, Philippines, Marshall Islands, Hawaii, Gulf of Mexico, Florida and the Bahamas. In the Southern hemisphere they have been identified in the Seychelles, New Caledonia, and the Coral Sea off Northern Australia. It is possible that the sharks seen in some of these unlikely locations have followed currents or prey away from the more common feeding grounds.

Diet
Young white sharks will eat a variety of marine life including fish and crustaceans. They are opportunistic feeders and will eat an expanding variety of sea life as they grow older. Once they reach approximately nine foot their primary food source begins to include marine mammals. The diet of the great white includes - mullet, salmon, lingcod, tuna, rays and skates, penguins, seals, sea lions, porpoise, dolphin, other sharks. Carrion, especially whale carcass, is also a favourite. Although great whites are seen as ferocious feeders, it is believed their low metabolic rate will enable them to last up to three months between meals.
