The Green vine snake (Ahaetulla nasuta), is a slender green tree snake found in India, Sri Lanka, Bangladesh, Myanmar, Thailand, Cambodia and Vietnam. It is diurnal and mildly venomous, normally feeding on frogs and lizards. Green vine snakes are slow moving, relying on camouflaging as a vine in foliage to hunt.
The snake expands its body when disturbed to show a black and white scale marking. Also, they may open their mouth in threat display and point their head in the directionof the perceived threat. There is a widespread myth in parts of southern India that the species uses its pointed head to blind its human victims.
