Description
Like all crocodilians, the American crocodile is a quadruped, with four short, splayed legs, a long, powerful tail and a scaly hide with rows of ossified scutes running down its back and tail. Its snout is elongated and includes a strong pair of jaws. Its eyes have nictitating membranes for protection along with lachrymal glands, which produce tears.
The nostrils, eyes, and ears are situated on the top of its head, so the rest of the body can be concealed underwater for surprise attacks. Camouflage also helps it prey on food. The snout is relatively longer and narrower than that of the American alligator, although broader on average than that of the Orinoco crocodile. American crocodiles are also paler and more grayish than the relatively dark-hued alligator. This crocodile species normally crawls on its belly, but it can also "high walk". Larger specimens can charge up to 10 mph (16 km/h). They can swim at as much as 20 mph (32 km/h) by moving their bodies and tails in a sinuous fashion, but they cannot sustain this speed.
American crocodiles are more susceptible to cold than American alligators. While an American alligator can survive in water of 7.2 °C (45.0 °F) for some time, an American crocodile in that environment would become helpless and drown. American crocodiles, however, have a faster growth rate than alligators, and are much more tolerant of salt water.

“Everything to which we concede existence is a posit from the standpoint of a description of the theory-building process, and simultaneously real from the standpoint of the theory that is being built. Nor let us look down on the standpoint of the theory as make-believe; for we can never do better than occupy the standpoint of some theory or other, the best we can muster at the time.”
