Sri Lanka wolf snake is an endemic and nocturnal species of snakes found in Sri Lanka. They mainly live in lowland wet and submontane zones and prefer damp forest areas. Above photographed one also found while it was in a wet place of the forest ground. This species is non-venomous. But it greatly mimics deadly venomous Sri Lankan krait in morphology and coloration. This snake has identically sized rough scales on the back and those have been keeled. But Kraits have large hexagonal line of scales running down the spine and the body of the Krait is shiny compared to the Sri Lankan wolf snake.
