Colorado Desert Shovel-nosed Snake

Subgenus Chionactis
Sonora annulata
(Baird 1859)
San Diego Co., California. May 17, 2015.

Jeff Nordland and I were road-cruising near Anza Borrego State Park, when I saw this pretty snake crawling off the asphalt and onto the shoulder. Never mind the stub-tail; I consider it one of the most beautiful snakes I’ve been privileged to see. In the Chionactis subgenus. In 2018, Sonora was elevated to a ‘supergenus’ containing Chilomeniscus, Chionactis, and Sonora as subgenera. For more information, see:
