American Alligators are most at home in rivers, swamps, wetlands and lakes. They enjoy a diet of fish, frogs, birds, mammals and invertebrates. Their sharp teeth capture prey, and their strong jaws are powerful enough to crack a turtle’s shell. As cold-blooded reptiles, alligators have to protect themselves from extreme heat or cold. They do this by digging and burrowing into tunnels as deep as 65 feet!
