Key identifying features
The Tiger Rattlesnake (Crotalus tigris) is a small rattlesnake notable for the numerous narrow, closely spaced crossbands running down its body, resembling tiger stripes, combined with a disproportionately small head and unusually large rattle for its body size. This combination of fine banding and rattle-to-body proportion helps distinguish it from other small desert rattlesnakes.
Coloration & pattern
Base coloration is typically pale gray, lavender-gray, buff, or pinkish, sometimes with a bluish cast. Numerous narrow, dark grayish or brownish crossbands, often 35 to 50 in number, cross the body from neck to tail, giving a finely banded, tiger-striped appearance. The pattern can appear faint or washed out in some individuals, especially toward the front of the body, becoming more distinct toward the tail.
Head, eyes & scales
The head is notably small relative to the body compared to other rattlesnakes, though it retains the typical broad, triangular pit viper shape with vertical pupils and heat-sensing facial pits. Faint markings may be present on the head but are often obscured. Scales are keeled.
Size & body shape
Adults are relatively small for rattlesnakes, typically ranging from 18 to 30 inches. Despite its modest body size, the Tiger Rattlesnake has a notably large rattle proportional to its body, a distinctive trait among rattlesnake species.
Range & habitat where you'll see it
This species is found primarily in south-central Arizona and adjacent Sonora, Mexico, favoring rocky slopes, canyons, and desert scrub in the Sonoran Desert region, often near boulder-strewn hillsides and arroyos.
How to tell it apart from look-alikes
The Speckled Rattlesnake shares similar desert rocky habitat but shows a stippled, grainy pattern rather than the Tiger Rattlesnake's numerous narrow crossbands. The Western Diamond-backed Rattlesnake is considerably larger with bold diamond blotches rather than fine tiger-like bands, and has a proportionally larger head. The unusually small head combined with numerous narrow crossbands and a comparatively oversized rattle is the most reliable identification combination for the Tiger Rattlesnake within its limited Arizona and Sonora range.
