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 general biology follows 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 are a key feature 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.
