Key identifying features
The barred coral snake (Calliophis intestinalis and related species) is a small, slender, highly venomous elapid found across Southeast Asia. It is best identified by its vivid red or orange body crossed with narrow black bars or bands, along with a brightly colored, often red or pink underside of the tail that can be flashed as a warning display.
Coloration & pattern
The dorsal surface is typically bright red, orange-red, or reddish-brown, crossed by narrow, evenly spaced black bars or bands that do not fully encircle the body in some populations, differing from the complete rings of many true coral snake species elsewhere. The tail's underside is frequently a vivid red or pink, sometimes displayed by curling the tail upward as a defensive warning signal when threatened.
Head, eyes & scales
The head is small and not strongly distinct from the neck, typically dark or black on top, sometimes with a pale band just behind it. The eyes are small and dark. Scales are smooth and glossy throughout the body, giving it a sleek, polished appearance typical of many elapids.
Size & body shape
Adults typically reach 30 to 50 cm (about 12 to 20 inches), with a slender, cylindrical body and a moderately short tail. This small, slim build is consistent with many Asian coral snake species, which tend to be smaller overall than their American counterparts.
Range & habitat where you'll see it
This species is found throughout Southeast Asia, including Malaysia, Indonesia, Thailand, and the Philippines, typically inhabiting lowland forest, leaf litter, and agricultural areas. It is fossorial and secretive, rarely seen in the open except at night, after rain, or when soil and leaf litter are disturbed.
How to tell it apart from look-alikes
The barred coral snake's narrow black bars on a red body, combined with its vividly colored tail underside used in defensive display, help distinguish it from other similarly colored snakes in the region. Unlike some fully ringed coral snakes, its banding pattern may be less complete around the belly, but the bright tail-flashing behavior and overall slender build remain useful identification cues when observed carefully and safely from a distance.
