Key identifying features
Bocourt's Coral Snake is a true coral snake, identifiable by its bold pattern of complete rings encircling the body in red, black, and yellow or white, a slender cylindrical body, and a small head that is not distinct from the neck. As with other elapids, it lacks the triangular, neck-distinct head shape seen in many venomous pit vipers.
Coloration & pattern
The body shows a repeating sequence of wide red bands separated by narrower black and yellow or white rings that fully encircle the body, giving a continuous banded appearance from the dorsal surface around to the belly. The precise ring sequence and width can vary somewhat by individual and population, but the rings remain complete rather than broken along the belly, a key trait of true coral snakes.
Head, eyes & scales
The head is small, rounded, and barely distinguishable from the neck, lacking the broad triangular shape common in vipers. The eyes are small with round pupils, another trait distinguishing true coral snakes from pit vipers, which have vertical pupils. Scales are smooth and glossy throughout the body.
Size & body shape
Adults are generally slender and moderate in length, with a smooth, cylindrical body that tapers evenly toward a short tail. The uniform, non-tapering neck-to-head transition is a useful identification cue at a glance.
Range & habitat where you'll see it
This species inhabits humid forest and forest-edge habitats in parts of northwestern South America, particularly Colombia and Ecuador, often found in leaf litter, under logs, or moving across the forest floor, and is largely secretive, spending much of its time hidden or burrowed.
How to tell it apart from look-alikes
Many harmless snakes in the same range mimic coral snake coloring, so ring completeness, sequence, and pattern details are important for identification, though this varies by region and should not be relied upon alone. The small, rounded, neck-blending head and round pupils help distinguish true coral snakes from unrelated venomous pit vipers, which have triangular heads, vertical pupils, and heat-sensing pits.
Frequently asked questions
How can you tell a true coral snake from a mimic species?
True coral snakes typically show complete rings that encircle the entire body including the belly, while many mimics have broken or incomplete ventral banding, though ring patterns can vary regionally so caution is warranted.
Is Bocourt's Coral Snake venomous?
Yes, it is a venomous elapid, though this guide focuses only on visual identification rather than any medical guidance.
What head features distinguish this species from a pit viper?
It has a small, rounded head that blends into the neck with round pupils, unlike the triangular, neck-distinct head and vertical pupils of pit vipers.
Where is Bocourt's Coral Snake typically found?
In humid forest and forest-edge habitats in northwestern South America, especially Colombia and Ecuador, often hidden in leaf litter or under logs on the forest floor.
