Species Description
This large rattlesnake can be found in the southwestern corner of California and south into Baja California including several islands. Its distinctive and bright red coloration develops as it ages from juvenile into adulthood. It inhabits elevations below 5000' and prefers rocky outcrops, hillsides, and coastal scrub habitats.
Fun fact: The population on Isla San Lorenzo de Sur is known to lose its rattle after shedding frequently. About half of the population on this island may lack a rattle entirely. The mainland population, however, retains its rattle.
