DESCRIPTION
Bright green with green belly. Males are smaller than females. Both male and female have characteristically triangular shaped head with large yellow/gold eyes containing vertical pupils. Can have purple/brown coloration on the tail.
BEHAVIOR
Active at night and occasionally roosting in bushes during the day. The Cardomom Pit Viper is an ambush predator that will wait in a single position ready to strike. As a viper they have relatively long retractable fangs and will bite readily at anything that comes within range. Generally not prone to give chase but will hold their ground if they feel cornered. Not actively aggressive but will not hesitate to bite. A bite from a Cardomom Pit Viper should be considered very serious and medical attention should be sought immediately. Although not known to be deadly serious damage can occur from a bite even if treated and complications can always arise.
HABITAT
Found in Vietnam, generally in forested areas along open spaces like trails, jungle slopes or water culverts where geckos and other prey can be ambushed. Previously not known to position near populated locations with artificial light, this species has been observed by the authors more and more frequently near street lamps and other man made locations.
MISTAKEN IDENTITY
NO SNAKE SHOULD EVER BE HANDLED BY ANYONE BUT EXPERTS: Often confused with the harmless Green Cat Snake. No viper should ever be approached or handled. If found observe from a safe distance.
