Alligators are large reptiles. They are members of the order Crocodylia.

An alligator is distinguished by its wide, rounded snout and black color. Also, all of its upper teeth can still be seen when its mouth is closed. There are two different types of alligator, and they vary in size. The American alligator can grow up to 11.2 feet (3.4 meters) long and weight nearly half a ton (1,000 lbs. or 454 kilograms. Both males and females have an "armored" body with a muscular, flat tail. Alligators are carnivorous. They have very strong jaws that can crack a turtle shell. They eat fish, snails and other invertebrates, birds, frogs and mammals that come to the water's edge.
