    Western Diamondback Rattlesnake – Crotalus atrox

    The most common rattlesnake species in Arizona, Western Diamondback Rattlesnakes are both generalists in their diet, consuming a variety of rodents and lizards, as well as generalists in their habitat. They are also the largest rattlesnake species on the west coast identified by a grey to tan body with brown diamond shaped dorsal blotches and a black and white striped tail with equal size banding.
