The Javan keelback water snake is a species of snake in the family Colubridae. The account used here gives it as endemic to Java and Bali, so its Sumatran listing should be checked. It is a common species typically encountered in rice paddies, but also occurs near lakes, rivers, streams and marshes (Wikipedia, general species account).
