Distribution and habitat
It is found in bushes and other low vegetation along tidal rivers and mangrove in coastal parts of Myanmar (Burma).[1][3][4] 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.[1][4] It is generally common in appropriate habitats within its known range.[1]
Description
It is slender, up to about 1 m (3 ft) long, and either green or brownish with a paler underside.[3]
The snout is pointed and projected, measuring approximately twice the size of the eye. It usually has two pairs of loreal scales; two pre-oculars, the upper one in contact with the frontal; two post-oculars; temporals 2+2 or 2+3; supralabials 7 or 8 with the 5th or 6th in contact with the eye. Ventral scales 183-195, subcaudals 115-151, anal scales divided. The holotype was 82 cm long.[5]
Behavior
This diurnal, mildly venomous snake feeds only on fish.[1][3][4] 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.[3]
