Twin Spotted Rattlesnake High on Mt. Graham

A Twin Spotted Rattlesnake that we found in eastern Arizona, showing off many more than “twin” spots. These tiny rattlesnakes can vary greatly in appearance from one location to the next, even between individuals in a single population. These are not likely to be seen unless you are spending time in the highest areas of a handful of the Chiricahua, Huachuca, Pinaleño, or Santa Rita mountain ranges.

Banded Rock Rattlesnake On Lichen-Covered Rock

Banded Rock Rattlesnake from southeastern Arizona. These snakes, typically the males, can have a metallic blue-green shine along the back and outline of black bands, often against other bright pinks, blues, and orange. It matches the lichen covering rocks where they live. This one is a good example of a mature male of the species against the rocky backdrop of its habitat. From the uniform size of its rattle segments, it can be determined that it’s reached full size.
