This montane rattlesnake is usually found in rocky areas of pine-oak woodland or coniferous forests, though they might also be found amongst saguaros in the Sonoran desert upland. Easily recognizable by their namesake blacktail, they often frequent tree branches or shrubs several feet above the ground.
Mohave Rattlesnake (Crotalus scutulatus) Unlike many rattlesnake species which hibernate in large groups, the Mohave hibernates alone or in groups of only two or three individuals. Though somewhat difficult to tell apart from the western diamond-backed rattlesnake, mohaves are slightly greenish in coloration, and their tail bands have thick white bands with narrower black bands. The venom of the Mohave rattlesnake is a potent blend of hemotoxins (break down cells and tissues) and neurotoxins (affect the nervous system, cause heart failure and/or respiratory paralysis) and is extremely dangerous.
