CARNIVORES
Almost all sharks are
"carnivores" or meat eaters. They live on a diet of fish
and sea mammals (like dolphins and seals) and even such prey as turtles
and seagulls.
Sharks even eat other
sharks. For example, a tiger shark might eat a bull shark, a bull
shark might eat a blacktip shark and a blacktip shark might eat a dogfish
shark!
The teeth of the carnivores are
sharp and pointy. Their skeleton is made of cartilage instead of
bone, which allows greater flexibility.
Their skin is made of denticles
instead of ordinary fish scales. The denticles are constructed like
hard, sharp teeth and help to protect the shark from injury.
