Agkistrodon piscivorus leucostoma
The Western Cottonmouth is often incorrectly referred to as a "water moccasin." Unfortunately, this incorrect name has been used for almost any dark snake found in or near water. Coloration is similar to the two eastern subspecies, except that most specimens tend to become darker at a younger age. Also, the light line that borders the dark cheek strip—clearly defined in A. p. conanti and less so in A. p. piscivorus -- is usually not present in this subspecies. A dorsal color pattern consists of 10 to 15 dark crossbands can be seen in small specimens, as well as in some larger ones.
The Western Cottonmouth does not venture far from a permanent source of water such as a bayou, slough, or pond
