Günther's whipsnake, Burmese vine snake or river vine snake (Ahaetulla fronticincta) is a species of snake found in bushes and other low vegetation along tidal rivers and mangrove in coastal parts of Myanmar (Burma). 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. It is generally common in appropriate habitats within its known range.
