Overview

The Guatemalan Milk Snake is a Central American subspecies within the milk snake complex, occurring from southern Mexico through Guatemala and Belize. It displays the vivid tricolor banding characteristic of many milk snakes in this region.

It inhabits tropical lowland and foothill forests, where its coloration may provide protective mimicry of venomous coral snakes sharing its range.

How to identify it

  • Bold red or orange bands bordered by black, separated by yellow or cream rings
  • Smooth, glossy scales
  • Small, rounded head not distinct from the neck, round pupils
