     Crocodilians are cold-blooded relatively ancient reptiles of about 200 million years. Ancient crocodilians have measured over 60 feet long. Fortunately, the American Alligator is well on the way to recovery. In its habitat it plays  important roles like keeping water holes open, controls rabid raccoons and rattle snakes and is the "watch dog" for other animals. 
     Unlike the American Alligator, the American Crocodile is an endangered species. Its nesting sites have almost been eliminated. They are not as bold as the alligator. 
     The rounded or shovel shape of the alligator's head versus the triangular tapering shape of the crocodile is the most visual distinguishing features. Both generally become lighter in color as they age. The crocodile's teeth can usually be seen even with its mouth closed.

     A couple of older references are Alligators and Crocodiles by Laurie Perrero, 1975 and Wonders of Alligators and Crocodiles by Wyatt Blassingame, 1973.
