Class: Reptilia
Order: Crocodylia
Family: Alligatoridae
Genus: Alligator
Species: mississippiensis

American alligators have long "armored" bodies, short legs, and they use their long, flat tails to propel them through the water. They're found in freshwater swamps, marshes, lakes and rivers. Is it a gator or a croc? It's all in the teeth! When their mouthes are closed, you can see the crocodile's fourth tooth on its lower jaw. You won't see this tooth on an alligator.
