Overview

The Side-striped Palm Pit Viper is a small, arboreal pit viper found in the cool, misty cloud forests of Costa Rica and western Panama, where it lives almost exclusively among vegetation.

Its vivid green coloration and prehensile tail make it well adapted to a life spent climbing through shrubs and low trees in montane forest habitats.

How to identify it

  • Bright to bluish-green dorsal coloration
  • Pale yellow or white stripe running along each side of the body
  • Slender build with a prehensile tail
  • Triangular head with vertical pupils
  • Keeled scales giving a slightly rough texture
  • Distinguished from other green palm pit vipers by the distinct lateral stripe

Habitat & range

Found in montane cloud forest and premontane wet forest, generally at moderate to high elevations in Costa Rica and adjacent western Panama.

Behavior, diet & reproduction

Arboreal and largely nocturnal, ambushing small frogs, lizards, and rodents from perches in vegetation. Ovoviviparous, giving birth to live young. Relies on camouflage and slow, deliberate movement.
