|DESCRIPTION: A small (up to 380 mm or 15″ in total length), relatively stout-bodied, gray, yellow-brown, or tan colored snake with more than 25 dark gray or brown, zigzag shaped bars across the back. A brown or gray-brown mask crosses the top of the head and covers the eyes on most specimens. The underside is pale or white, often with a pinkish or salmon tint. The pupils are round. The scales are smooth. The snout (rostral scale) is upturned on the leading edge and flat or concave on top.
DISTRIBUTION: This snake occurs in the foothills, bajadas, and valleys of southeastern Arizona at elevations below approximately 6,000′.
HABITAT: It is primarily associated with Chihuahuan Desertscrub and Semidesert Grassland communities but it is also encountered in Madrean Evergreen Woodland. In Arizona this snake is most frequently encountered on gentle sloping bajadas or in low foothills with rocky or gravelly soil grown with creosotebush or grasses. It is also occasionally encountered in the lower reaches of mountainous terrain along ridges and in canyons.
DIET: The Chihuahuan Hook-nosed Snake feeds on small spiders, insects, centipedes, and scorpions. Captive specimens have also eaten snakes, lizards, and small mice.
REPRODUCTION: A clutch of up to 4 eggs is laid in late spring or early summer.
