Mojave Rattlesnake (Crotalus scutulatus)
All upset and ready for business!

General Description: Often called a Mojave Green Rattlesnake, this is a large, dark greenish or olive-green rattlesnake with well-defined dark diamonds down the center of the back clearly offset with light borders. The tail has black and white bands, but the black bands are much narrower than the white bands.

This species can be confused with Western Diamondback Rattlesnakes. However, Mojave Rattlesnakes have narrow black bands on the tail and the upper white eyestripe extends beyond the corner of the mouth.

These snakes are venomous. Do not attempt to handle rattlesnakes; rather, enjoy your good luck of finding one from a distance (minimum 4 feet away) and leave them alone.

Taxonomy: Pit Vipers Family (Viperidae)

Mojave Rattlesnake (Crotalus scutulatus)
Note enlarged scales on snout

Technical Description: A medium sized (4 ft) rattlesnake; body heavy. Head shape wide and triangular. Dorsal color dark greenish or olive-green with well-defined dark diamonds, ovals, or hexagons down the center of the back. Dorsal marks offset with light edges. Tail with narrow black and broad white rings (white rings twice as wide as black rings). White eye stripe extends from behind the eye to beyond the corner of the mouth. Enlarged scales on the snout and between the supraoculars.

Diet: Feeds on rodents, snakes, lizards, birds, and eggs.

Habitat: Mojave Desert Scrub (Upper Sonoran Life Zone) and lower mountain slopes. Not common in rocky areas or areas with dense vegetation. Probably widespread throughout southern Nevada in the appropriate habitat.

Range: The species occurs in southeastern California, southern Nevada (north to about the Nevada Test Site), and western Arizona east along the border to southwestern Texas and south into Mexico. This subspecies occurs in the U.S.

Note the white stripes on the side of the face.

Breeding: Gives birth to 2-11 live young during mid-summer.

Similar Species: Other species of rattlesnake lack the greenish cast or have less-distinct markings, but definite identification may require careful examination of the scales on the top of the head and snout (not recommended). The Mojave Rattlesnake has large scales on the top of the head, while the Western Diamondback Rattlesnake has granular scales atop the head. In addition, in the Western Diamondback Rattlesnake, the rear eye stripe extends from behind the eye to the upper lip ahead of the corner of the mouth.
