Overview

The Peruvian Desert Coral Snake occupies a niche unusual for the genus Micrurus, inhabiting arid and semi-arid coastal valleys rather than humid rainforest. It is known from only a limited number of localities in northern Peru.

Its venom and general biology follow the elapid pattern of its relatives, though its arid habitat sets it apart ecologically from most coral snakes.

How to identify it

  • Red, black, and white/yellow rings encircling the body in the classic coral snake pattern
  • Small head with blunt snout, not distinct from neck
  • Smooth scales
  • Round pupils
  • Adapted coloration may appear slightly muted compared to rainforest relatives
  • Complete body rings separate it from any non-venomous mimics in its arid range

Habitat & range

Restricted to dry coastal valleys and adjacent scrublands of northern Peru, an atypical arid habitat for a coral snake. Found under rocks, leaf litter, and loose soil.

Behavior, diet & reproduction

Fossorial and rarely seen, likely more active during cooler or wetter periods in its arid habitat. Diet presumed to consist of other snakes and lizards, consistent with the genus. Oviparous reproduction is expected, though details are poorly documented due to its rarity.
