Crotalus pricei pricei - Western Twin-spotted Rattlesnake

Description

Adults usually do not exceed 50–60 cm (about 20-24 inches) in length. The maximum length recorded is 66 cm (26 inches).

The color pattern consists of a gray, bluish gray, brownish gray, or medium to reddish brown ground color, usually with a fine brown speckling. This is overlaid with a series of dorsal blotches that tend to be divided down the median line to form 39-64 pairs.

Etymology

The specific name, pricei, is in honor of William Wightman "Billy" Price, a field biologist, who collected the first specimens which became the type series.

Common names

Conservation status

This species is classified as Least Concern (LC) on the IUCN Red List of Threatened Species (v3.1, 2001).

The population trend is stable. Year assessed: 2007.
