Bull Shark Teeth

Evolving millions of years ago, bull sharks can still be found in any warm coastal water all over the world, including fresh water rivers. Males can grow to about 7 feet (2.1 meters) in length, and females grow to 11 feet (3.3 meters) or more. Adults usually weigh between 200 and 500 pounds (91 to 227 kilograms). These sharks hold the record for the strongest bite to size comparison of any shark, and are the inspiration behind the move Jaws.
