Sri Lankan Green Vine Snake

Ahaetulla nasuta


All vine snakes are venomous with grooved fangs below the eye; however, most species are harmless to humans. They normally feed on frogs and lizards. They are slow moving, relying on camouflaging themselves as vines.


Found in low bushes, shrubs and trees in lowland forest terrain, particularly near streams and often found near human settlements.


They expand their bodies when disturbed to show a black and white scale marking. They may open their mouths in a threat display and point their heads in the direction. They are the only species of snake with horizontal pupils, compared to the normal vertical slit pupils found in many species of viper.
