A small male White-lipped Pit Viper with yellow eyes, spotted on the side of a rubber trash bin near a waterfall in Suan Hin Pha Ngam limestone garden, in Loei province.

When it moved, the thin white ventrolateral stripe, that runs along its body, became clearly visible. This particular species has rather large eyes, making it confusingly similar to the Big-eyed Pit Viper (fig.).

VENOMOUS! This snake is semi-dangerous. It has a hemotoxic venom and has a very painful bite, and though usually not fatal, in severe envenoming its is potentially lethal. Its bite may further lead to local pain, swelling, bruising, blistering, shock, moderate to severe coagulopathy and haemorrhagins with extensive bleeding, minor necrosis.
