Members of this superfamily first arose in the late Cretaceous, about 10065 million years ago (Mya). [53] There is also fluctuation in the level of bacterial taxa populations in the alligator's microbial community between seasons which helps the alligator cope with different rates of feeding and activity. Almost all of the high-density populations of alligators live south of the Albermarle sound, although some individuals have been reported through the entire coastal region of the state.

[84] Stomach contents show, among native mammals, muskrats and raccoons are some of the most commonly eaten species. Unlike an American crocodile, which would immediately succumb to the cold and drown in water at 45F (7C) or less, an American alligator can survive in such temperatures for some time without displaying any signs of discomfort. Most of the state gets much too cold for gators to survive the winter, but there are some small regions that allow for a small population. For the history, the United States is the only nation on earth where both alligators and . Historically, the American Alligator was common and abundant throughout the southeastern United States.

This experiment had not been, at the time of the paper published, replicated in any other crocodilians, and the same laboratory was able to measure a greater bite force of 16,414N (1,673.8kgf; 3,690lbf) in saltwater crocodiles;[51][52] notwithstanding this very high biting force, the muscles opening the American alligator's jaw are quite weak, and the jaws can be held closed by hand or tape when an American alligator is captured. Most animals captured by American alligators are considerably smaller than itself. In the future, possible American alligator populations may be found in areas of Mexico adjacent to the Texas border.
