The Trinidad Coral Snake shows the classic true coral snake pattern of complete red, black, and yellow rings encircling the body, a pattern consistent with related mainland coral snakes but restricted to the island of Trinidad and nearby areas. Its small, rounded, non-triangular head is a key feature separating it from venomous pit vipers that may share similar coloration in mimicry.
Coloration & pattern
The body pattern consists of broad red bands separated by black bands, each black band bordered by thin yellow rings, forming a repeated sequence that wraps entirely around the body, including the belly. The black coloration typically extends over the snout and crown of the head. Band proportions may vary slightly between individuals, but the banding always fully encircles the body rather than stopping at the flanks.
Head, eyes & scales
The head is small, rounded, and not clearly set apart from the neck, lacking the broadened, triangular shape typical of vipers. Eyes are small and dark with round pupils. Scales are smooth and glossy, giving the snake a sleek, polished appearance typical of the coral snake group.
Size & body shape
This is a slender, small to medium-sized snake, generally reaching 40 to 70 centimeters in length, with a uniformly cylindrical body and a short tail, suited to its secretive, ground-dwelling and burrowing habits.
Range & habitat where you'll see it
The Trinidad Coral Snake is restricted to the island of Trinidad and nearby areas of northern South America, where it inhabits forested lowlands, leaf litter, and moist soil habitats. It is secretive and rarely seen in the open, typically found under logs, leaf litter, or forest debris, especially after rainfall.
How to tell it apart from look-alikes
The fully encircling bands of red, black, and yellow, combined with its restricted island range, distinguish this species from mainland coral snakes and non-venomous mimic species, which often show incomplete banding across the belly. As with all coral snakes, correctly distinguishing true species from mimics depends on careful attention to whether the bands wrap completely around the body, and identification should be approached cautiously given the medical significance of the group.
