Alligators are fierce predators. They have armored bodies, powerful jaws and muscular tails. Scientists estimate that they have been around for more than 150 million years.
Contrary to popular belief, alligators make sounds. They do so to warn away intruders, to attract a mate or when two males fight for territory. The sound they make is a cross between a growl and a roar.
In contrast to adult alligators, which can grow up to 15 feet long, baby alligators are just 6 to 8 inches long. They have yellow and black stripes.Learn more about Alligators
