Shark teeth Sharks have an unlimited amount of teeth. Some sharks lose 30,000 or more teeth in their lifetime. Their tooth shape depends on their diet sharks on mollusks and crustaceans have dense flattened teeth to crush their prey, those that feed on fish have razor sharp teeth for gripping and those that feed on larger prey have pointed lower teeth for gripping and triangular upper teeth with serrated edges for cutting. In most species teeth are replaced once at a time, except cookie cutter sharks, the whole row of teeth is replaced. Click to go to picture

For example, the hammerhead shark has a head shaped like a hammer,the whale shark is as big as a whale; and the reef shark lives on coral reefs.
