Description

The Trans-Pecos spotted whiptail is gray or black in color, with six to eight yellow or white stripes which run along the body from head to tail. Unlike other species of whiptail lizards, they have no spotting between their stripes. Their undersides are white or pale blue in color, and often they have light blue on the sides of their heads and tails. They are thin-bodied, and have a tail that is typically almost three times the length of their bodies.

Behavior

Like most species of whiptail lizard, Trans-Pecos spotted whiptails are diurnal and insectivorous.
