This is a genuine alligator skull. Based on it's size, the alligator would have been about seven feet long. American alligators are the larger of the two alligator species, often growing to more than twice the length of Chinese alligators. The muscles that close the animal's mouth are extremely strong, but the muscles that open the mandible are comparatively weak, such that a typical human can safely hold an alligator's mouth closed with two hands. Although alligators are an apex predator, they feed primarily on small mammals and fish which they can eat in one bite. When hunting larger prey, the alligator will grasp the animal with its mouth and drag it into a body of water. It holds its prey underwater to drown it before tearing the animal into chunks that are small enough to swallow.
