Overview
The Sonoran Mountain Kingsnake inhabits rocky, montane habitats across Arizona, parts of Utah, New Mexico, and northern Mexico. Its bold banding is a textbook example of Batesian mimicry, resembling the pattern of the Arizona coral snake found in overlapping range.
Despite its coral snake-like colors, it is entirely non-venomous and preys on small vertebrates.
How to identify it
