Barren desert, grassland, open juniper woodland, and scrubland. They frequent open creosote bush or mesquite flatlands, away from areas of broken rocky terrain and dense vegetation.


Mammals (mice, rats, squirrels, rabbits), and other reptiles.


Throughout most of its range Mohave Rattlesnakes have a powerful neurotoxic component to their venom. However, some populations in central Arizona lack the neurotoxin.


Due to its neurotoxic venom, this snake is considered extremely dangerous.
