I'm scared, really scared. Debra Abercrombie photographs the sharks during the shark dive. Shark teeth, scary as they are, are also pretty cool. Some sharks, like the great white and tiger, have teeth that are sharp for sawing. Others, like the sand tiger, have sharp pointy teeth used to grab and hold prey.
All sharks have extremely powerful jaws to complement their teeth.
Tigers and great whites have bitten right through surfboards and the people on them. Most sharks are constantly replacing their teeth. Similar to a conveyor belt, new teeth pushing the front teeth out. So there are many rows of teeth in the shark's mouth at all times. These reefs and blacknoses have small teeth with fine serrations for sawing through prey smaller than themselves.
