The western ground snake (Sonora semiannulata) is a species of small, harmless colubrid snake. The species is endemic to North America. It is sometimes referred to as the common ground snake or variable ground snake, as its patterning and coloration can vary widely, even within the same geographic region. Another common name is miter snake referring to the head marking which suggests a bishop's miter; the synonym 'episcopus' (Latin for 'bishop') is a similar allusion. The western ground snake can grow to a total length (including tail) of 8 to 19 inches (20.3 to 48.3 cm). The color and pattern can vary widely. Individuals can be brown, red, or orange, with black banding, orange or brown striping, or be solid-colored. The underside is typically white or gray. It has smooth dorsal scales, a small head, and the pupil of the eye is round. The western ground snake is typically nocturnal and secretive, but it is common throughout its range. It is often found on roadsides, or in dry drainage ditches at night, foraging for food. (Source: Wikipedia.org, CC BY-SA)
