Common checkered whiptail

Species of lizard

The checkered whiptail is a species of lizard found in the southwestern United States in Colorado, Texas and New Mexico, and in northern Mexico in Chihuahua and Coahuila. Many sources believe that the species originated from the hybridization of the marbled whiptail, Aspidoscelis marmorata, the plateau spotted whiptail, Aspidoscelis septemvittata, and possibly the six-lined racerunner, Aspidoscelis sexlineata. It is one of many lizard species known to be parthenogenic. It is sometimes referred to as the common checkered whiptail to differentiate it from several other species known as checkered whiptails.
