Ceylon Wolf Snake

The Ceylon wolf snake is a colubrid endemic to Sri Lanka, known in Sinhala as daara karawala. The back is black with 19 distinct white rings, which may be reduced or absent in adults, and the black bands extend onto the belly but are fairly diffuse. The scales are keeled and dull. It was moved to the genus Lycodon in 2013 from Cercaspis (Wikipedia, general species account).

It is nocturnal and terrestrial, hiding under rubble in forests during the day. Its diet comprises frogs, geckos, skinks and small non-venomous snakes. It is oviparous, laying 4 to 7 eggs at a time. No status is given for it in the Sri Lanka National Red List 2012 list checked.
