Species Description

This species can be found in the Central Plateau region of Mexico. It is quite small at about 26 inches long on average. The Central Plateau pygmy rattlesnake feeds on small mammals, lizards, insects, and other snakes. In 2018, the subspecies under C. ravus were all elevated to species status due to newfound phylogenetic evidence. Prior to 2009, this species had been listed under the genus Sistrurus, with the Pygmy Rattlesnake and Massasaugas, but genetic evidence found that it was closer related to other montane rattlesnakes of Crotalus than to the other pygmies of Sistrurus.

The venom of this species has been shown to have antibacterial effects against bacteria that can cause pneumonia and other infections, especially in hospitals!
