SOUTHERN PRAIRIE LIZARD
Sceloporus undulatus consobrinus
Southern Prairie lizards are the only fence lizard found in the Trans-Pecos region. They are found over almost all of the western 2/3 of Texas

They are a medium sized spiny lizard, attaining snout-vent lengths of around seven inches.

This particular lizard was found in a culvert between Alpine and Maraton in Brewster County, following some rains. When I first saw it, my first thought was "mudskipper", as the lizard was swimming in water.
