Crotalus cerastes

Desert Sidewinder
Viperidae

One of three rattlesnake species found in the Mojave region, Crotalus cerastes is potentially the least dangerous. A small rattler, this snake is known best for its characteristic sidewinding locomotion when crossing areas of loose sand or silt. Though less aggressive and venomous than Crotalus scutulatus, the Mojave green rattlesnake, C. cerastes is still a venomous snake, and can inflict a painful, and potentially lethal, bite. As with all venomous snakes, keeping one's distance and letting the snake have its space is the best way to interact with them.

Aside from the snake's distinctive locomotion, one of the most iconic features of this species are its supraocular scales, giving the snake the appearance of having horns just above its eyes. These are handsome snakes, and if given their space, are a pleasant treat to see when in the field.

Lichanura trivirgata

Rosy Boa
Boidae

One of two spcies of Boidae native to the united states, L. trivirgata is an uncommon sight in the canyons of the Mojave. Found occupying rocky, granitic outcrops, these snakes are almost obligately ambush predators, being too slow moving to hunt down and capture prey. Like all members of Boidae, these snakes are non-venomous constrictors, capturing prey and
suffocating it by progressively tightening its body as the prey exhales.


They tend to be active during the warmer parts of the day, while staying under shelter during the hottest and coldest times of the year. These boas, like most members of the family, are ovoviviparous, giving birth to live young, usually in broods of six.
