Below is a current list of the 164 species and subspecies of lizards that occur in the region that we have defined as
being the American Southwest. Six (6) of these are introduced species. Our goal is to eventually have at least one photo for every species/subspecies. We also plan to eventually provide habitat photographs for some species and the legal/protection status of each in the states where
they occur.

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 inclusion. Please see our Call for Papers and Photos section for more information.
