Sri Lanka is primarily an agricultural country, resulting in a fair number of people being bitten by these green pit vipers while plucking tea leaves, clearing forests, and weeding.
The neck is distinct from the flattened, triangular head. The eyes are mid-size and the snout is short, rounded and broad. The Sri Lankan pit viper camouflages well with the forests it lives in. Typically, it is a green snake with a black pattern and a black line along side of its head is present. The males tend to have a blue coloration while the females are predominantly green.
The genus of snake this species belongs to, Trimeresurus, are commonly known as the green pit vipers. They are widespread throughout most of tropical Asia and account for many bites, especially amongst agricultural workers.
