Description:

The keeled bellied water snake is endemic to the Andaman coasts of Thailand and Myanmar and it may be present on the Sunda Shelf. It is known from relatively few specimens. It feeds of gobies and has some unusual morphology including keeled ventral scales, dorsal scales with exposed skin, and the general appearance of a true sea snake - which it may mimic.
