Did you know there are over 400 different species of sharks? Did you know they have been on Earth much longer than humans, and even lived before the dinosaurs? Here you'll learn all about these fearsome kings of the ocean, including their eating habits and the basics of their anatomy. Sharks come in many sizes, from under a foot long to over 40 feet-and that's not even counting the long-extinct, 60-foot-long Megalodon shark.
