Humans are the only animals killing American alligators, through hunting and habitat loss.
Adult American alligators have very few predators, but they do get eaten by black bears on rare occasions. A bigger alligator will occasionally eat the adult alligator. The youngs get preyed on by big fish, wading birds, monitor lizards, and water snakes.
