Crotalus ruber lorenzoensis is a venomous pitviper subspecies[3] endemic to San Lorenzo Sur Island, Mexico. It is sometimes treated as a full species, Crotalus lorenzoensis.[1]
Description
This subspecies usually has no rattle, and has shrunk in size compared to some of its other subspecies counterparts on the mainland.[4]
Geographic range
Known only from the type locality, which is "San Lorenzo Sur Island in the Gulf of California, Baja California Norte, Mexico."[2]
Habitat
It occurs mainly in rocky areas and arroyo bottoms. It can also be found in dunes near the coast and in cavities formed by adjacent boulders.[1]
Conservation status
This species is classified as "Least Concern" (LC) on the IUCN Red List of Threatened Species.[1] 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.[5]
