About the Green Vine Snake

Ahaetulla nasuta, also known as Sri Lankan green vine snake, long-nosed whip snake, and long-nosed tree snake, is a venomous, slender green tree snake endemic to Sri Lanka. It was previously known as the common green vine snake and was widely distributed across India and South East Asia, until a 2020 study split them into several different species, restricting Ahaetulla nasuta just to the Sri Lankan population.

The genus name Ahaetulla comes from the Sri Lankan Sinhalese words ahaetulla/ahata gulla/as gulla, meaning "eye plucker" or "eye picker", because of the belief that they pluck out the eyes of humans, as first reported by the Portuguese traveler João Ribeiro in 1685.
