Below is a current list representing the one (1) species of crocodilian that is native to the region that we have defined as being the American Southwest.

Our goal is to eventually one or more photographs for every species/subspecies. We also plan to eventually provide habitat photographs and range maps for as many species as possible along with the legal/protective status of each in the states where they occur within our region.

To help maintain some degree of taxonomic stability and reduce confusion, SWCHR has elected to take a conservative taxonomic approach when deciding which scientific and common names to utilize in this species listing. Please click here for an explanation of our philosophy regarding taxonomic issues. In cases where we have elected not to follow either Scientific and Standard English Names of Amphibians and reptiles of North America North of Mexico with Comments Regarding Confidence in Our Understanding, 6th Edition, 2008 by Brian I. Crother, et al or Standard Common and Current Scientific Names for North American Amphibians, Turtles, Reptiles, and Crocodilians, 7th Edition (2009) by Joseph T. Collins and Travis W. Taggart, we have linked a taxonomic note to the listing which explains our reasoning.

Those species and subspecies that do have photos available are identified as clickable links on the list below. If you have photos of species/subspecies that do not yet have photos, you are encouraged to submit them for possible inclusion.

ALLIGATORIDAE  (Alligators and Caimans)

American Alligator - Alligator mississippiensis  (audio file included)
