The most widely distributed snake species in the world, found across the entire tropical Indo-Pacific and occasionally further afield, spending its entire life in open ocean far from shore — unlike most sea snakes, which stay closer to coasts.

Distinctively coloured black above and bright yellow below, drifting at the surface to ambush small fish sheltering beneath floating debris. Venomous, and essentially unable to move on land if stranded; occasionally washes ashore after storms.
