Erpeton is a genus of water snake of the family Colubridae, which includes a single known species, the tentacled snake, Erpeton tentaculatum, which is native to South-East Asia. They are aquatic and extremely fast in catching their prey, small fish. The snakes accomplish the capture of their prey by cheating on a C-start escape reflex of the fish: after a fish approaches, the snake bends, and makes a quick movement with a measured segment of its body, startling the fish exactly in the direction of snake's head.
