Great White Sharks By: ArianaAdam
Where Are They? They are found in: Great whites can be found along the coastlines of South Africa, Australia, New Zealand, California to Alaska, the east coast of USA and the Gulf coast, Hawaii, most of South America, the Mediterranean Sea, West Africa to Scandinavia, Japan and the eastern coastline of China and southern Russia.
Habitat The white shark lives mainly in the upper part of the water column, near the shore. However, it ranges from the surf line to well offshore and from the surface and to depths of over 250m (775ft). This shark commonly patrols small coastal islands inhabited by pinnipeds (seals, sea lions and walruses), offshore reefs, banks and rocky headlands where there is deep water close to shore. The white shark usually cruises either just off the bottom or near the surface.
Physical Features The Great White Shark has a heavy spindle- shaped body. They have an exceptionally long conical snout. They are huge, flat and triangular, too. The sharks have blade-like teeth with long gills with slits. The Great White has a huge first dorsal fin with a light rear tip. The fish has a pivoting second dorsal and anal fin. Most of their body is white. Their nostrils are lateral to their snout and their teeth in the upper jaw are big.
Reproduction It is believed that the Great White Sharks breed by internal fertilization and that the young sharks eat other fertilized eggs while growing inside the mother shark. New information indicates that there are 9 - 11 young sharks in a litter.
Diet Young Great Whites eat fish, rays and other smaller sharks. Adult Great Whites eat larger prey like sea lions, seals, small whales and dolphins, otters, and sea turtles. They will also eat the carcasses of other animals. Great White sharks have to eat about every two months.
Special Instincts • The Great White Shark's nostrils can smell one drop of blood in 25 gallons of water. • The Great White is the only shark that pokes it's head out of the water. No one knows why but they think the shark tries to see prey.
