DESERT MASSASAUGA, BUZZTAIL FACTSDescription
The Desert Massasauga is a small rattlesnake with a light gray or white base color, with dark gray or gray brown blotches. There is a dark stripe along the side of the head passing over the eye. The rattles are quite high pitched compared with some of the larger species of rattlesnake. The underside is nearly white. They are mainly nocturnal, and avoid the heat of the day in summer. The Desert Massasauga is paler in color, smaller and more slender than the Western Massasauga (S. c. tergeminus).

30cm - 50cm.
rocky semi-arid and arid areas, desert grasslands.
rodents, lizards and frogs.
They give birth to living young (ovoviviparous). Breeding occurs during the late summer and up to 7 live young are born the following year.
Found in south eastern Arizona, central and southern New Mexico, western Texas. Also found in northern Mexico.
Massasauga has more potent venom than some larger species of rattlesnakes, but it cannot deliver as much in a single bite, reducing its potential danger. They are not considered to be deadly, but venom can cause swelling, necrosis, and severe pain. Seek immediate medical treatment for any venomous snake bite.
