Overview

The bamboo pit viper is a venomous arboreal species native to peninsular India, often encountered in bamboo groves and dense forest vegetation from which it takes its common name. Its uniform green coloration provides effective camouflage among leaves.

While its venom is medically significant, bites are usually less severe than those of larger vipers, though still requiring caution.

How to identify it

  • Uniform bright to olive green dorsum, sometimes with a faint pale lateral stripe
  • Slender, laterally compressed body suited for climbing
  • Triangular head distinct from the neck with heat-sensing pits
  • Vertically elliptical pupil
  • Prehensile tail aiding in climbing
  • Distinguished from other green pit vipers by range and subtle scale differences

Behavior, diet & reproduction

Nocturnal and arboreal, ambushing frogs, lizards, and small rodents from vegetation. Remains motionless for long periods, relying on camouflage before striking. Ovoviviparous, producing live young.
