Key identifying features
The Assam Trinket Snake is a slender, glossy-scaled colubrid recognized by a series of dark blotches or crossbands set against a lighter brown to olive background, which can create a chain-like or ornate pattern reminiscent of other trinket snakes. Its smooth scales and alert, large eyes reflect an active, largely diurnal to crepuscular lifestyle.
Coloration & pattern
The dorsal pattern typically features a series of dark brown or blackish blotches, sometimes edged with lighter borders, running down the back over a tan, yellowish, or olive base color. Toward the tail, the blotches may become narrower or fuse into partial bands. The head often shows darker markings or streaking, including lines running back from the eyes, which is common in the trinket snake group.
Head, eyes & scales
The head is moderately elongated and slightly distinct from the neck, with large prominent eyes and round pupils typical of active, sight-hunting colubrids. Scales are smooth and glossy over most of the body, giving it a sleek appearance in good light. A dark line or streak often extends from behind the eye toward the neck, aiding recognition of the trinket snake group.
Size & body shape
This species is slender and moderately long, with adults commonly reaching lengths of around 100 to 150 centimeters. The body is laterally compressed to some degree, which combined with its slenderness gives it an agile, quick-moving build well suited to climbing as well as ground movement.
Range & habitat where you'll see it
The Assam Trinket Snake is associated with forests, forest edges, and adjacent agricultural or shrub habitats in northeastern India and neighboring regions. It is often found in trees, shrubs, and on the ground, showing a flexible semi-arboreal lifestyle typical of trinket snakes.
How to tell it apart from look-alikes
The blotched, chain-like dorsal pattern combined with the dark eye streak helps separate this species from plain-colored or uniformly striped colubrids in the same region. Compared to other trinket snakes, its particular blotch shape, coloration tone, and geographic restriction to northeastern India help narrow identification. Its smooth glossy scales and slender build also distinguish it from the rougher-scaled keelbacks and heavier-bodied pit vipers found in overlapping habitats.
