A species of lowland primary forests, the Triangle Keelback is diurnal and semi-aquatic. It feeds mainly on fish and frogs, including frogs eggs. The specimen in these photos is feeding on the eggs of the Jade Tree Frog Rhacophorus prominanus.

It is easily identified by the orange-red or orange-yellow sides and the regularly spaced inverted black triangles. The dorsal surface of the head is olive-green and the body olive-green or olive-brown. The dorsal scales are keeled.

The species ranges from Burma, Thailand and Indo-China to Peninsular Malaysia, Singapore, Sumatra, Borneo and Java.
