SHARKSDid you know that sharks are older than dinosaurs? In some form, sharks have been around for about 400 million years. Some species are extinct. Sharks are such expert hunters. They have few enemies. The biggest shark is the Megalodon. It has lived until 12,000 years ago. Even before dinosaurs roamed the earth, sharks hunted through the oceans! They're such good survivors that they've had little need to evolve in the last 150 million years. These ancient predators fascinate adults and children alike. Scientific Information: Sharks belong to the class of fish, Chondrichthyes. SHARK TEETHSharks have the most powerful jaws on the planet. Unlike most animals' jaws, both the sharks' upper and lower jaws move. A shark bites with it's lower jaw first and then its upper. It tosses its head back and forth to tear loose a piece of meat which it swallows whole.
