Shark Jaw

DINNER TIME
Normally, sharks eat alone. But sometimes one feeding shark attracts others. They swim up as quickly as possible and all begin to try to get a piece of the prey. They bite wildly at anything that gets in their way -- even each other.
Oddly enough, the great white shark rarely partakes in feeding frenzies.
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.
JawsIn most sharks, the mouth is beneath the snout. The jaws are loosely connected by ligaments and muscles to the skull, and are very mobile. When a shark starts to bite, its snout bends up and out of the way. The jaws move forward and protrude. When the shark bites its prey, the jaws move back and under the snout again. This happens very quickly.
