Common names: El Muerto Island speckled rattlesnake.[3]

Crotalus mitchellii muertensis is a venomous pitviper subspecies[4][5] endemic to El Muerto Island, Mexico. It is sometimes treated as a full species, Crotalus muertensis.[1]

Description[edit]

A dwarfed form, adults grow to a maximum length of 63.7 centimetres (25.1 in).[3]

Geographic range[edit]

Known only from the type locality,[3] which is "El Muerto Island, Gulf of California, Mexico."[2]

Habitat[edit]

It is common in all habitats within the El Muerto Island: rocks and rubble of talus slopes, scrub, hill ridges, and the intertidal zone.[1]

Conservation status[edit]

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.[6]
