Sidewinder Rattlesnake

Crotalus cerastes


17 - 33 in. (43-84 cm). The side wise locomotion, with the body moving in an S-shaped curve, is characteristic. Back generally pale, harmonizing with background - cream, tan, pink, or gray, patterned with grayish, yellowish brown, or tan blotches down back. A dark eye stripe. Supraoculars hornlike, pointed, and upturned - this snake is sometimes called the "horned rattler." The horns may fold down over the eyes when the snake crawls in burrows. Scales keeled usually in 21 rows at mid body.




This sidewinder is a baby, only about 12" long with just 1 button on his rattle.
