Green Pits

Bamboo Pit Viper (Trimeresurus gramineus) is an arboreal snake found in Western Ghats. Its green colour helps it camouflage in trees.  It is a vicious hunter of the canopies. Equipped with haemotoxic venom this snake has another adaptation that makes it special. It has the heat sensing pits. Located between the eyes and nostrils, these give the snake an additional benefit of sensing temperature changes around it. When shot from a head on angle, it makes the snake look even more intense.
