How to Identify the Lesser Black Krait (Identification Guide)
The Lesser Black Krait is a slender, highly venomous elapid identified by its glossy black to dark blue-black body, faint or absent banding, and smooth, hexagonal vertebral scales typical of kraits.

Key identifying features
The Lesser Black Krait is identified by its overall glossy black to deep blue-black coloration, generally lacking the bold white or pale crossbands seen in many other krait species, or showing only very faint traces of banding. Along with the smooth scales and enlarged, hexagonal row of vertebral scales characteristic of the krait genus, this predominantly dark, understated appearance is the primary field mark.
Coloration & pattern
The body is typically a uniform glossy black or very dark blue-black, sometimes with a faint bluish sheen visible in good light. Unlike many banded kraits, this species shows little to no obvious pale crossbanding, or the banding may be reduced to faint, poorly defined markings that are difficult to see except in bright light or at close range. The belly is generally paler, often white or cream, contrasting with the dark back.
Head, eyes & scales
The head is small and only slightly distinct from the neck, typical of kraits, and is usually as dark as the body with little contrasting pattern. The eyes are relatively small with round pupils. A key scale feature shared by all kraits is an enlarged row of hexagonal scales running down the center of the back, which can be seen as a distinct ridge-like row when examined closely.
Size & body shape
Adults typically reach around 0.6 to 1 meter in length, making this one of the smaller krait species. The body is cylindrical in cross-section toward the front and becomes more triangular in profile toward the rear, a subtle shape change common among kraits. The tail is relatively short and tapering.
Range & habitat where you'll see it
The Lesser Black Krait inhabits lowland and hill regions of parts of South and Southeast Asia, favoring forests, agricultural land, and areas near water sources. It is nocturnal and secretive, sheltering during the day under debris, in burrows, or dense vegetation, and becoming active at night to forage.
How to tell it apart from look-alikes
The Lesser Black Krait's largely unbanded, uniformly dark coloration distinguishes it from more boldly banded krait species such as the Banded Krait or Many-banded Krait, which display strong, well-defined pale crossbands. It can be separated from other all-dark snakes by checking for the enlarged hexagonal vertebral scale row, a diagnostic trait of the krait genus not found in most superficially similar black snakes.
Frequently asked questions
Is the Lesser Black Krait dangerous?
Yes, it is highly venomous, like other kraits, though it is generally secretive and nocturnal, reducing encounters with people.
How does the Lesser Black Krait differ from banded kraits?
It lacks the bold, well-defined pale crossbands seen in species like the Banded Krait, instead appearing mostly uniform black or very faintly marked.
What scale feature helps confirm a krait identification?
An enlarged row of hexagonal scales running down the center of the back, a trait shared by all kraits.
How large does the Lesser Black Krait get?
Adults typically reach between 0.6 and 1 meter in length, making it one of the smaller krait species.
Where does the Lesser Black Krait live?
In lowland and hill habitats of parts of South and Southeast Asia, active mainly at night near forests and water sources.
