<human>: I'd like to know the difference between the crocodile and the alligator.
<bot>: The main difference is that crocodiles are found in fresh water, while alligators inhabit saltwater habitats. Crocodiles also have longer snouts than alligators, as well as more prominent ridges along their back. Alligators typically grow much larger than crocodiles, with some species growing up to 20 feet long.
