Species Description

The Isla Angel Rattlesnake is endemic to the island of Isla Angel de la Guarda in the Gulf of California. It was previously considered a subspecies of the Speckled Rattlesnake (Crotalus mitchelli), but was elevated to full species status in 2015. Younger individuals are pinkish-cinnamon colored with brown dorsal blotches and dark speckles intermixed; their color becomes more brown or gray as they age.

Habitat includes rocky areas such as arroyos (dry gulleys), rocky outcrops, talus and shorelines on the 47 mile long island. They can be found in the lower areas of the island, up to 500m. The Angel de la Guarda Island speckled rattlesnake is a generalist and has been recording consumes birds, mammals, and lizards. Although there aren't any mammalian predators on the island, kingsnakes are present, and they have been recorded consuming this rattlesnake species.
