Alligators are apex predators and fear no other animal within their ecosystem, although they are known to be timid around humans. This fear is beneficial for both species and is one reason why humans should not feed alligators, as they may begin to associate humans with food.
The American alligator is a large member of the Crocodilia order and is native to the southeastern United States. A smaller relative, the Chinese alligator, lives in the Yangtze River valley. The American alligator can grow more than 15 feet in length and exceed 1,000 pounds in weight. The diet of the American alligator includes a wide variety of fish, mammals, amphibians and reptiles.
