Crocodylus acutus
Usually, American alligators are dominant over and more behaviorally aggressive than American crocodiles. However, on one occasion, an American crocodile in a Florida zoo escaped its cage and started a fight with a large male American alligator in a bordering pen, and was killed by the alligator. Conversely, there is one confirmed case of an American crocodile preying on a sub-adult American alligator in the wild in Florida. American alligators and American crocodiles do not often come into conflict in the wild, due largely to habitat partitioning and largely separate distributions.
