Mark Sanders Tampa says that alligators are large amphibious reptiles of the crocodilian family. There are two main species, The American Alligator and the Chinese Alligator. The Alligator is one of the oldest species on earth, fossils as old as 200 million years have been unearthed. Despite being notorious for their bone-crushing bite, Alligators are docile next to the comparatively ferocious Crocodile, from which they are easily distinguished by their snouts. A crocodile has a long, pointed snout with overlapping teeth (creating their infamous ”smile”), while Alligators snouts are broad and even.
