How to Identify Russell's Kukri Snake (Identification Guide)

Key identifying features

Russell's Kukri Snake is distinguished by a series of bold, dark, saddle-shaped blotches or bands along a lighter body, glossy smooth scales, and a distinct dark marking on the head or nape that often stands out clearly against the paler ground color.

Coloration & pattern

The dorsal background is typically pale brown, tan, or grayish-buff, marked with a row of dark brown to blackish saddle blotches or bands that run the length of the body, sometimes connecting along the sides to form a more continuous banded look. A prominent dark mark, often shaped like an arrowhead or inverted V, is commonly present on the back of the head or nape, a feature frequently used to help confirm identification. The belly is usually plain pale cream or white, contrasting with the patterned dorsum.

Head, eyes & scales

The head is small and not strongly distinct from the neck, with a blunt, rounded snout. Eyes are moderate in size with round pupils, and the pupil shape combined with the overall head shape is consistent with the nocturnal, secretive habits typical of kukri snakes. Body scales are smooth and glossy, producing a shiny, sleek appearance rather than the rough keeled texture of unrelated water and keelback snakes.

Size & body shape

Adults are small to medium-sized, generally falling in the range of 40 to 70 cm in total length. The body is slender and rounded, tapering to a moderately short tail, with proportions typical of ground-dwelling, semi-fossorial kukri snakes.

Range & habitat where you'll see it

Russell's Kukri Snake occurs in South Asia, typically in forested and semi-forested lowland and hill habitats, often near human settlements, gardens, and agricultural land. It is nocturnal and secretive, usually found under rocks, logs, or leaf litter during the day and active on the surface at night.

How to tell it apart from look-alikes

The combination of bold dorsal saddle blotches with a distinctive dark nape marking is the most useful way to separate this species from other similarly patterned kukri snakes, which may differ in the precise shape, number, or spacing of their blotches. Smooth, glossy scales and a small head distinguish it from rough-scaled keelbacks and from venomous banded species such as kraits, which tend to have a duller scale sheen. Because closely related kukri snakes can look superficially similar, comparing the exact pattern of the nape marking alongside overall blotch shape offers the most reliable field identification.
