California Ground Squirrel Immune to Rattlesnakes?
A California Ground Squirrel (Otospermophilus beecheyi) out getting some sun while keeping a keen eye on the tourists. California Ground Squirrels over one month in age are partially immune to rattlesnake poison. The females are also known to chew on rattlesnake skins and lick themselves and their pups to disguise their scent. Photo taken at the Tijuana River National Estuarine Research Reserve.
