Hiding in the Trees

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.
