Overview
The California Mountain Kingsnake occurs in a variety of forested and rocky habitats along the Pacific coast from Oregon through California into Baja California. It exhibits a striking red, black, and white tricolor pattern.
Although it does not overlap in range with true coral snakes, its coloration is thought to derive from an ancestral mimicry adaptation and now serves as general predator deterrence.
