The Mojave rattlesnake, Crotalus scutulatus, ranges from southeastern Nevada through much of Mexico. In Utah, it occurs only in the extreme southwestern corner of the state, where it can be found in barren desert and desert scrub habitats.

The Mojave rattlesnake is primarily nocturnal, avoiding the heat of the day. Females are live-bearing, and give birth to as many as seventeen young during late summer. Mojave rattlesnakes eat a variety of small mammals (such as kangaroo rats, rabbits, and mice), as well as lizards and occasionally other snakes. Individuals are greenish, brownish, or yellowish in color, with well-defined darker colored patches of diamonds, ovals, or hexagons running down their backs.
