Key identifying features
The Ceylon Krait (Bungarus ceylonicus) is a slender, glossy black or dark brown snake marked with narrow white or pale crossbands along its body, a pattern generally less bold than that of the Common Krait. A single row of enlarged vertebral scales runs along the spine, a shared trait of all krait species that helps confirm identification.
Coloration & pattern
The body is dark, typically black or very dark brown, crossed by thin white or pale yellow bands that are often narrower and more widely spaced than in the Common Krait. These bands may be faint or incomplete, particularly toward the head, and some individuals show reduced or irregular banding overall. The underside is pale white or cream.
Head, eyes & scales
The head is small and not strongly distinct from the neck, with small eyes and round pupils. Scales are smooth and glossy throughout. The enlarged vertebral scale row is present as in other kraits, forming a subtle ridge visible along the mid-back.
Size & body shape
This is a comparatively small krait, with adults typically reaching around 0.6 to 0.9 meters, noticeably smaller than the Common Krait. The body is slender and cylindrical with a gentle dorsal ridge.
Range & habitat where you'll see it
The Ceylon Krait is endemic to Sri Lanka, where it inhabits wet zone forests, plantations, and areas near human habitation at low to mid elevations. It is nocturnal and terrestrial, often found near water sources, under leaf litter, or in and around human dwellings and gardens.
How to tell it apart from look-alikes
Within Sri Lanka, the Ceylon Krait can be confused with the Common Krait, which also occurs on the island; however, the Ceylon Krait is generally smaller and its banding tends to be narrower and less distinct. Careful attention to overall size and the width and spacing of the pale crossbands helps separate the two species, along with range and habitat context. As with other kraits, the presence of the enlarged vertebral scale row helps distinguish it from superficially similar harmless banded snakes such as wolf snakes.
