The American alligator is a large reptile native to the southeastern United States. It typically inhabits freshwater environments such as swamps, rivers, and lakes. Adult alligators can grow up to 13 feet long and weigh over 800 pounds. They are known for their powerful jaws and distinctive armored skin. These reptiles are carnivorous and primarily feed on fish, birds, and small mammals. The American alligator plays a crucial role in its ecosystem by helping to control prey populations. They are also a keystone species, meaning their presence supports the health of their habitat.
