What's your first impression of sharks
There are over three hundred different species of shark. The unusual thing about all these fish is the fact that they have no bones! Their entire skeleton (骨架) is made up of cartilage (软骨). Different sharks have different shapes of teeth. The great white shark has very sharp teeth that are able to tear big pieces of its prey (猎物). Most of sharks feed on sea creatures like fish, squid and crabs. The great white shark has been known to eat seals.
Sharks have excellent sight. They also have a very good sense of hearing and pick up sounds of struggling fish far away, sounds that would not be heard to the human ear. They also have a very keen sense of smell and are attracted by the smell of blood coming from an injured fish.
