This small (20-24 inches long) rattlesnake can be found in seasonally dry pine-oak forest in several south-central Mexican states. This species is typically found between 6500 and 12000 ft elevation.
Fun fact: This species, Crotalus intermedius, was separated into several different populations and have begun to diverge due to the warming of the climate and loss of connecting habitat since the Quaternary Period thousands of years ago. Cooler periods which allow for its habitat to expand downward may allow for reconnectivity and gene flow in the future.
