Key identifying features

The west Mexican coral snake displays the classic true coral snake pattern of complete red, black, and yellow rings encircling a slender body, paired with a small, blunt, black-tipped head. It is restricted to Mexico's Pacific versant, making location a useful clue alongside its coloration.

Coloration & pattern

Bands of red, black, and yellow wrap fully around the body in a repeating sequence, typically with black bands bordered by narrow yellow rings on either side and broader red bands between them. The pattern is bright and high-contrast, continuing uninterrupted onto the belly, which is characteristic of true coral snakes as opposed to mimics.

Head, eyes & scales

The head is small and rounded, not clearly wider than the neck, and colored black across the snout and crown. Eyes are small and dark, largely camouflaged within the black head coloration. Scales are smooth and glossy over the entire body.

Size & body shape

This is a slender, small to medium-length snake with a cylindrical body and a relatively short tail, typical of the coral snake group. The thin build aids movement through loose soil and leaf litter.

Range & habitat where you'll see it

As its name implies, this species occurs along the Pacific slope of western Mexico, inhabiting tropical dry forest, thornscrub, and adjacent semi-humid habitats. It is secretive and largely fossorial, spending much time hidden underground or under surface litter, emerging mainly after rains or during cooler parts of the day.

How to tell it apart from look-alikes

The complete encircling rings of red, black, and yellow—including on the belly—distinguish it from nonvenomous mimic snakes with similar coloring but incomplete banding. Its restricted range along Mexico's Pacific coast, combined with the classic true coral snake body pattern, helps narrow identification when compared to other coral snake species found in different parts of Mexico and Central America.
