Today, the American alligator is no longer endangered, but it is still a "protected species." It is protected because the alligator looks like some species of crocodiles and caimans, which are still endangered. Because of this, the Fish and Wildlife Service categorizes the American alligator as “threatened due to similarity of appearance.” Their goal is to prevent people from killing endangered crocodiles and caimans because they have mistaken an alligator for a crocodile or caiman. Because of this, killing alligators, and trading in products made from alligator meat or skin, are all regulated by the Fish and Wildlife Service.
