Crotalus concolor, commonly known as the midget faded rattlesnake, faded rattlesnake and yellow rattlesnake,[citation needed] is a pit viper species found in the western United States. It is a small rattlesnake known for its faded color pattern. Like all other pit vipers, it is venomous. This snake grows to a maximum length of 75 cm (29+1⁄2 in). The smallest gravid female measured was 52.2 cm (20+1⁄2 in). The color pattern of this species consists of a pinkish, pale brown, yellow-brown, straw-colored, reddish, or yellow-brown ground color, overlaid with a series of brown elliptical or rectangular dorsal blotches. However, most specimens are gray or silvery. In juveniles, the pattern is distinct, but becomes faded in adults, almost to the point where it is indistinguishable from the ground color.
