<human>: I'm trying to find out if there is a difference between an alligator and a crocodile.
<bot>: Alligators are members of the family Alligatoridae, while crocodiles are members of the family Crocodylidae. The two families are closely related but have different physical characteristics. An alligator has a snout that is more rounded than a crocodile's and its teeth are not as long or sharp. An alligator also typically has larger scales on its back than a crocodile does.
