shark teeth


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.
