The short-horned lizard (Phrynosoma hernandesi) is a small lizard that occurs in North America. Like other horned lizards, it is often wrongly called the "Horned Toad" or "Horny Toad," but it is not a toad at all. It is a reptile, not an amphibian. It is one of seven native species of lizards in Canada. The species name, hernandesi, honors Francisco Hernández Médico who wrote an early account in 1651 of a Horned Lizard.
The range extends from southern Alberta and southern Saskatchewan south through eastern Montana, the western Dakotas, Wyoming, western Nebraska, Colorado, Utah, eastern Nevada, New Mexico, Arizona, and mountains of western Texas to southern Durango (Zamudio et al. 1997, Stebbins 2003); the range limit in the vicinity of Idaho, western Wyoming, northern Utah, and northern Nevada has not been precisely determined. Elevational range extends from 170 to around 3,440 m (900 to 11,300 feet) (Stebbins 2003).
