The American alligator is a large reptile native to the southeastern United States. They typically inhabit freshwater environments like swamps, rivers, and lakes. Adult alligators can grow up to 13 feet long and weigh over 800 pounds. Their dark, armored bodies help them blend into their surroundings, making them effective predators. These alligators are cold-blooded and rely on external heat sources to regulate their body temperature. They primarily feed on fish, birds, and small mammals. During the breeding season, which occurs in spring, males attract females with vocalizations and displays.
