Crotalus pricei is a
Etymology
The specific name, pricei, is in honor of William Wightman "Billy" Price (1871–1922), a field biologist, who collected the first specimens which became the type series.[6][7][8]
Description
Adults of C. pricei usually do not exceed 50–60 cm (about 20–24 in) in total length (including tail). The maximum total length recorded is 66 cm (26 in).[3]
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.[3]
Behavior
Amid the mountain rocks where it lives, this small snake may rattle furiously at passing humans yet never be heard. The nights are often cold where it lives. It is driven by hunger, seeking out small rodents and lizards. Though its pattern looks bizarre its protective coloration blends well with the light and shadow of the mountains. Although it has been conjectured that it has a venom of high potency, little is known - there are no recorded bites to humans from this snake. [9]
Common names
Common names for C. pricei include twin-spotted rattlesnake,[3] western twin-spotted rattlesnake,[4] Price's rattlesnake, Arizona spotted rattlesnake, spotted rattlesnake,[10] and Arizona twin-spotted rattlesnake.[11]
Geographic range

Conservation status
This species, C. pricei, is classified as Least Concern on the IUCN Red List of Threatened Species (v3.1, 2001).[1] Species are listed as such due to their wide distribution, presumed large population, or because they are unlikely to be declining fast enough to qualify for listing in a more threatened category. The population trend was stable when assessed in 2007.[12]
