Crotalus ruber lorenzoensis is a venomous pitviper subspecies[2] endemic to San Lorenzo Sur Island, Mexico.

Description[edit]

This subspecies usually has no rattle, and has shrunk in size compared to some of its other subspecies counterparts on the mainland.[3]

Geographic range[edit]

Known only from the type locality, which is "San Lorenzo Sur Island in the Gulf of California, Baja California Norte, Mexico."[1]

Conservation status[edit]

This species is classified as Least Concern (LC) on the IUCN Red List of Threatened Species (v3.1, 2001).[4] 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 is stable. Year assessed: 2007.[5]
