Alligators live in primarily in fresh to brackish water of swamps, marshes, canals, and lakes. The American alligator is found only in the southeastern part of the USA from Southern Virginia to Florida and as far West as Texas.
Alligators are usually solitary animals. They have a life span of up to about 30 to 35 years in the wild, and up to 50 years in captivity. Crocodilians exhibit complex and advanced behavior as they interact with others and make survival decisions. They grow from 9 to 15 feet when they reach adulthood, making them the largest reptile in North America. Younger alligators are most vulnerable to predators and humans, and only a small fraction of alligators will live reach their full size.
