Key identifying features
The Red-Headed Krait (Bungarus flaviceps) is a striking and unmistakable species due to its vivid red or orange head, neck, and tail contrasting sharply against a glossy black or dark blue-black body. Unlike most other kraits, it lacks obvious crossbanding, instead relying on this bold two-tone coloration as its primary identifying feature.
Coloration & pattern
The head is bright red to orange-red, and this coloration often extends a short distance down the neck before transitioning to the dark body color. The tail is similarly colored bright red or orange at the tip. The body itself is a deep glossy black or very dark blue, often with a thin pale blue, white, or yellowish stripe running along each lower side of the body, bordering the ventral scales. The belly is pale, sometimes with dark markings.
Head, eyes & scales
The head is moderately distinct from the neck, larger and more visible than in some other krait species, with small eyes and round pupils. Scales are smooth and glossy. As with other kraits, an enlarged vertebral scale row runs down the spine, though it may be less conspicuous than in strongly banded species due to the lack of contrasting body pattern.
Size & body shape
This is a large krait, with adults commonly reaching 1.5 to 2 meters, occasionally larger, making it one of the biggest species in its genus. The body is moderately slender and elongated with a subtle dorsal ridge.
Range & habitat where you'll see it
The Red-Headed Krait is found in Southeast Asia, including Thailand, Malaysia, Myanmar, Indonesia, Vietnam, Cambodia, and Laos. It favors dense tropical rainforest and lowland forest habitats, often near streams or moist forest floor leaf litter. It is nocturnal and secretive, rarely encountered in open or heavily developed areas.
How to tell it apart from look-alikes
The combination of a bright red head and tail against a black body is highly distinctive and not closely matched by any other snake in its range, making misidentification unlikely once this feature is observed. It differs sharply from banded kraits, which show alternating light and dark crossbands rather than a solid black body with red extremities. Some other forest snakes may show reddish coloration, but none combine it with the black body, pale lateral stripe, and krait body proportions seen in this species.
