Crotalus oreganus caliginis is a venomous pit viper subspecies[4] endemic to South Coronado Island, Mexico.

Description

Adults grow to a maximum size of 68.3 cm (26+7⁄8 in).[3]

Geographic range

Known only from the type locality,[3] given as "South Coronado Island, off the northwest coast of Baja California, Mexico."[1]

Conservation status

This species is classified as least concern on the IUCN Red List of Threatened Species (v3.1, 2001).[5] Species are listed as such due to their wide distribution, presumed large population, or because it is unlikely to be declining fast enough to qualify for listing in a more threatened category. The population trend was stable when assessed in 2007.[6]
