The Santander Coral Snake is a slender true coral snake known from the Santander department of Colombia, sharing the characteristic ring pattern of the wider Micrurus genus. As with related species, its full-body encircling rings are the primary identifying feature, while its restricted regional range is a key supporting clue.
Coloration & pattern
The body is patterned with bold rings that wrap completely around the body, typically arranged in a repeating sequence of black, red, and pale yellow or white, though exact proportions and ring widths vary regionally within the coral snake group. These rings continue uninterrupted onto the belly, a defining trait of true coral snakes as opposed to many similarly colored mimics. The snout commonly shows a dark cap near the tip.
Head, eyes & scales
The head is small, narrow, and not distinct from the neck, blending into the body's banded pattern and making the head difficult to pick out at a glance. Eyes are small with round pupils. Scales are smooth and glossy, typical of the genus.
Size & body shape
This is a slender, elongated, cylindrical snake of small to moderate length, consistent with the general body plan of Micrurus coral snakes, adapted for a secretive, ground-dwelling or leaf-litter lifestyle rather than rapid open movement.
Range & habitat where you'll see it
This species is associated with the Santander region of Colombia, typically inhabiting humid forest and forest-edge habitats at low to moderate elevations. Like most coral snakes, it is secretive, spending much of its time hidden in leaf litter, under logs, or in soil, and is rarely seen in the open.
How to tell it apart from look-alikes
The defining feature separating true coral snakes such as this one from harmless mimics is that the rings continue fully around the body onto the belly, whereas many mimicking species show pattern breaks or incomplete banding on the underside. Distinguishing this species from other coral snakes found in overlapping parts of Colombia generally requires close attention to ring width, count, and sequence, along with locality information, since general coloration overlaps considerably across regional Micrurus species.
