Crotalus lorenzoensis usually has no rattle, and has shrunk in size compared to its counterparts on the mainland.[5]
Geographic range
Crotalus lorenzoensis is known only from the type locality, which is "San Lorenzo Sur Island in the Gulf of California, Baja California Norte, Mexico".[2]
Habitat
Crotalus lorenzoensis 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
The species C. lorenzoensis 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.[6]
