How to Identify the Bamboo Pit Viper (Identification Guide)
The Bamboo Pit Viper is a slender green arboreal viper identified by its triangular head, heat-sensing pits, and often a reddish or white lateral stripe along the body.

Key identifying features
The Bamboo Pit Viper is identified by its bright green body, distinctly triangular head, and the presence of heat-sensing pits between the eye and nostril, all standard pit viper features. A pale lateral stripe, sometimes white, yellow, or reddish depending on sex, running along the lower flank is a helpful additional field mark in many individuals.
Coloration & pattern
The dorsal coloration is predominantly bright to olive green, sometimes with a faint darker green or bluish tint along the back. A pale stripe, often white or yellow bordered with red in males, runs along the lower sides of the body in many individuals, though this feature can vary or be absent in females and some regional populations. The belly is typically pale green, yellow, or whitish, and the tail tip is often reddish brown, contrasting with the green body.
Head, eyes & scales
The head is broad, flattened, and strongly triangular, clearly set apart from the slender neck. Eyes have vertically elliptical pupils, often appearing golden or reddish, and heat-sensing pits are visible between the eye and nostril on each side. Dorsal scales are keeled, and the head bears small, irregular scales typical of pit vipers rather than large symmetrical plates.
Size & body shape
This is a small, slender snake, typically reaching 50 to 90 centimeters in length, with a laterally compressed body well adapted to climbing and moving through dense vegetation. The tail is prehensile-capable and often reddish or brownish, contrasting with the green body, aiding in balance among branches.
Range & habitat where you'll see it
The Bamboo Pit Viper is widely distributed across South and Southeast Asia, including parts of India, China, and surrounding countries, where it inhabits bamboo groves, forest edges, shrubland, and agricultural areas near vegetation. It is primarily arboreal and nocturnal, often found coiled on low branches, bushes, or bamboo stalks.
How to tell it apart from look-alikes
The combination of green coloration, triangular head, heat-sensing pits, and a contrasting reddish or brown tail tip helps distinguish this species from non-venomous green colubrids, which lack facial pits and typically have narrower heads. Compared to other green pit vipers in the region, the presence and coloration of the lateral stripe, along with geographic range, assist in narrowing down identification, though many green pit viper species appear quite similar and benefit from regional field guide comparison.
