Key identifying features
The Choco Coral Snake is a slender true coral snake associated with the Choco biogeographic region spanning parts of western Colombia and Ecuador, one of the most biodiverse rainforest areas in the world. Like other Micrurus species, its identification rests primarily on the presence of bold rings that fully encircle the body, along with its association with this specific humid rainforest region.
Coloration & pattern
The body shows a repeating sequence of vivid rings, typically combining black, red, and pale yellow or white, wrapping completely around the circumference of the body including the belly. Ring width and the exact number of color repeats (triads) vary somewhat between individuals and are among the details specialists use to separate this species from other regional coral snakes. The head often carries a dark cap near the snout tip.
Head, eyes & scales
The head is small, narrow, and barely distinct from the neck, following the typical Micrurus body plan and blending visually into the banded body. Eyes are small with round pupils, often difficult to make out against the surrounding pattern. Scales are smooth and glossy.
Size & body shape
This is a slender, cylindrical snake of small to moderate length, with an elongated, streamlined body suited to a secretive, ground-dwelling or leaf-litter existence rather than rapid movement across open terrain.
Range & habitat where you'll see it
The Choco Coral Snake inhabits humid lowland and foothill rainforest within the Choco biogeographic region of western Colombia and Ecuador, one of the wettest and most species-rich rainforest zones in the Americas. It is a secretive species, generally hidden beneath leaf litter, in soil, or under forest debris, and is rarely observed moving in the open.
How to tell it apart from look-alikes
As with other true coral snakes, the rings encircling the entire body including the belly distinguish this species from many harmless mimics with incomplete banding. Separating the Choco Coral Snake from other Micrurus species occurring in the same humid rainforest region typically requires close attention to ring sequence, count, and width, since general coloration overlaps substantially with related coral snakes; its strong association with Choco rainforest habitat is a useful supporting clue alongside detailed pattern examination.
Frequently asked questions
Where does the Choco Coral Snake live?
In humid lowland and foothill rainforest within the biodiverse Choco region of western Colombia and Ecuador.
What is its identifying color pattern?
Bold rings, typically black, red, and pale yellow or white, that wrap completely around the body including the belly.
How is it different from harmless coral snake mimics?
True coral snakes like this one have rings encircling the entire body, including the underside, while mimics often show incomplete banding restricted to the upper body.
Is this snake commonly seen in the open?
No, it is secretive and generally remains hidden in leaf litter, soil, or forest debris.
