The letter"T".he American Crocodile, also called the Florida Crocodile, is a distant 'cousin' of the American Alligator, sharing many bodily features, but rather distant genetically, having diverged in evolution from a common ancestor millions of years ago. This croc is the only species of crocodilian that naturally shares habitat with a member of the Alligator genus; together they inhabit tropical and sub-tropical southern Florida.


This website is intended to focus on the American Alligator, so this profile of the crocodile is not as extensive as that of the alligator. You may find it helpful to refer to the alligator section on "Thermoregulation" to supplement this article, as crocodilians control their body temperature in same way.

The American crocodile shown above, like its relatives among the crocodilian order, can remain still for long periods of time, yet are capable of startling bursts of movement; this may be done for the purpose of evasion, siezure of prey, or attack. The photos above clearly demonstrate physical features of the crocodile that contrast it from the alligator. Note the narrow snout, irregularly arranged scales, and color.
