Description
Script error: No such module "Unsubst". Adults of C. stejnegeri do not usually grow to more than Script error: No such module "convert". in total length (including tail). The greatest total length recorded for a specimen is Script error: No such module "convert"..[6] The tail is relatively long, representing 11.0-14.8% of the total length of adult male snakes and 9.8-12.5% in females. Klauber (1940) suggested that since the rattle is tiny, it is probably not audible. A very rare species, there have only been 12 specimens found.[1]Template:Update inline
Geographic range and habitat

Conservation status
Script error: No such module "Unsubst". C. stejnegeri is classified as Vulnerable on the IUCN Red List of Threatened Species with the following criteria: B1ab(iii) (v3.1, 2001).[8] A species is listed as such when the best available evidence indicates its extent of occurrence is estimated to be less than 20,000 km2 (7,720 mi2), estimates indicate it is severely fragmented or known to exist at no more than 10 locations, and a continuing decline has been observed, inferred, or projected in its area, extent, and/or quality of habitat. Therefore, it is considered to be facing a high risk of extinction in the wild. The population trend was down when assessed in 2007.[9]Template:Update inline
