The main difference between an alligator and a crocodile is that alligators are members of the family Alligatoridae, while crocodiles are part of the family Crocodylidae. Both species are found in the same habitats, but alligators tend to live in freshwater rivers and lakes while crocodiles prefer saltwater bodies such as oceans or large lakes. Additionally, alligators have more rounded snouts and shorter tails than crocodiles.
