Alligators and Crocodiles

All alligators are crocodiles, but not all crocodiles are alligators. Sound confusing? It's really not once you look at the taxonomy. Both alligators and crocodiles are members of the reptilian order Crocodylia. But the families they belong to, Alligatoridae and Crocodylidae respectively, differ. Crocodiles and alligators are top-notch hunters and will eat just about anything they can get their teeth on. Alligators and Crocodiles are among the largest reptiles.
