Overview

The Cardamom Mountains Green Pit Viper is a range-restricted species named for its association with the Cardamom Mountains of southwestern Cambodia, an area recognized for high levels of species endemism. It was distinguished from similar green pit vipers through detailed taxonomic study.

Its limited known range reflects the biodiversity significance of the Cardamom Mountains as a refuge for many endemic reptiles and amphibians.

How to identify it

  • Reddish or orange eyes with vertical pupils
  • Triangular head with heat-sensing pits
  • Slender body and prehensile tail typical of Trimeresurus
  • Keeled scales
  • Distinguished from related green pit vipers mainly by locality and subtle morphological traits
