Habitat
Great white sharks have been observed along the
coastlines of California to Alaska, the east
coast of the USA and most of the Gulf coast,
Hawaii, most of South America, South Africa,
Australia (except the north coast), New Zealand,
the Mediterranean Sea, West Africa to
Scandinavia, Japan, and the eastern coastline of
China and southern Russia.

Young great white sharks eat fish, rays, and
other sharks. Adults eat larger prey, including
pinnipeds (sea lions and seals), small toothed
whales (like belugas), otters, and sea turtles.
They also eat carrion (dead animals that they
have found floating dead in the water).

Facts
Great Whites are fish, but they differ in many
different ways. For example, their skeleton is
not made of bone, it is made of cartilage. A
shark's scales are not broad or smooth like most
other fish. They are very rough, like sandpaper!!

Many paleontologists are very interested in
living groups, because the study of the living
organisms can both unlock their evolutionary
history and provide important keys towards
interpreting their fossil record. Some living
groups have ancient histories. For example,
sharks have existed as a group for over 350
million years! Today, sharks and rays are
represented by over 600 species that show a
remarkable range of ecological and morphological
diversity. Unlike the true fishes, sharks do not
have internal bone, but instead have a
cartilaginous skeleton. Although many people are
told that sharks are primitive in comparison to
other groups, this is not true. Many sharks are
efficient and specialized hunters that have
thrived for millions of years.
