Mexican West Coast Rattlesnake

Crotalus basiliscus
(COPE, 1864)
Sonora, Mexico. August 25, 2011.

This young-of-the-year basiliscus was found road-cruising one night in southern Sonora, and is easily one of the most beautiful rattlesnakes I’ve ever seen. The adults resemble blacktailed rattlesnakes (Crotalus molossus) and the ones I’ve seen in southern Sonora often show a tinge of olive green. Like blacktails, many of the dorsal scales are unicolored, making for a contrasting (and pleasing) pattern.
