Ahaetulla fronticincta, commonly known as Günther's whipsnake, the Burmese vine snake or the river vine snake, is a species of fish-eating vine snake found in Southeast Asia.
It belongs to the genus Ahaetulla, one of five genera within the subfamily Ahaetuliinae. The relationships of Ahaetulla fronticincta to some other Ahaetulla species, and to the other genera within Ahaetuliinae, can be shown in the cladogram below, with possible paraphyletic species noted:[1]
It is found in bushes and other low vegetation along tidal rivers and mangrove in coastal parts of Myanmar (Burma).[2] [3] There are also old records from neighbouring northeastern India (Assam and Darjeeling), but these are considered questionable and it has not been located there during recent surveys.[3] It is generally common in appropriate habitats within its known range.
It is slender, up to about 1abbr=onNaNabbr=on long, and either green or brownish with a paler underside.[2]
This diurnal, mildly venomous snake feeds only on fish.[2] [3] It strikes at a fish in water while maintaining half of its body wrapped around a branch or twig. The mild venom of this snake renders the fish immobile.
It is ovoviviparous.[2]
