The sidewinder (Crotalus cerastes), also known as the horned rattlesnake and sidewinder rattlesnake, is a venomous pit viper species belonging to the genus Crotalus (rattlesnakes) and is found in the desert regions of the southwestern United States and northwestern Mexico. Crotalus cerastes is sometimes referred to as the horned rattlesnake because of the raised supraocular scales above its eyes. This adaptation may help shade the eyes or prevent sand drifting over them as the snake lies almost buried in it.
Mojave Desert sidewinder (Crotalus cerastes cerastes) is found in the United States in the desert areas from northeastern Los Angeles County and San Bernardino County, California, northward to southern Mono County, California, east across Nevada to Washington County, Utah, and south through Mohave County, Arizona in desert lowlands. |
