Whats' that Snake?

" The beauty of the snake is unmatched, something i haven't seen in a long time. The specimen is something about 6 inches long, but despite its size, its extremely agile. Deep olive above with bright yellow belly, it is distinguished by the presence of a single internasal.As i am not familier with this particular species from West Bengal, a chance of misidentification was inevitable. nevertheless with assistance from my friend Melvin Selvan, we did come to the conclusion that it was indeed a species of the genus Atretium.

" Atretium schistosum is a common snake in southern India, living in the water and among vegetation. in 2010 on a trip to south India we spotted a snake in a irrigation canal, totally submerged with its head only sticking on the surface of the water. it stayed thr for a while and then went below.feed on frogs and fish, known to breed during the rains. In Bengal this snake is rare and their choice of habitat makes them even more hard to find. It has been recorded in the State before, but proper documentation was lacking so far. Being known from only a handful of specimens, this is indeed a eureka moment for any enthusiast. "it was also noted that the snake is sharing the same habitat with Enhydris and Xenochrophis, as both the species were previously collected from that same area. here i noted something peculiar in the behavior of the specimen. When kept in a tank with land water ratio 1:3, it prefered to stay on land. when shifted to a larger tank with water, land and some branches, it either went on the land or climbed up the branch but never water. probably young snakes of this species do live a certain time on land and take the advantage of plentiful food there, rather than being eaten by fishes and other predators in water."
