Bamboo Pit Viper

Upper parts usually bright green, rarely yellowish, greyish, or purplish brown, with or without black, brown, or reddish spots; usually a light, white, yellow, or red streak along the outer row of scales; end of tail frequently yellow or red; lower parts green, yellow, or whitish. Grows to a total length of 2.5 feet (0.76 m); tail 5.5 inches (14 cm). The Crotalinae are characterised by the presence of a triangular head and heat-sensing pit organs located between the eye and the nostril on either side of the head. The pits are openings to a pair of very sensitive infrared detecting organs, which helps them to find the small warm-blooded prey on which they feed.
