It is just there for breaking up shape. I have been studying them for a while and I cant find any other reason for it to be there. unlike the Asian vine snakes. and the Genus of snake is (Langaha Nasuta) which is also called the madagascan vine snake or leaf nose snake. there are two different genus's on Madagascar of the leaf nose snake. langaha nasuta and langaha madagascariensis. they look much bigger in pictures than in real life. the one that I took a picture of is 2 feet long and as thick as a pen. so maybe now you can see why it was such a hard picture to take. and it moves really fast. its hard to take pictures with a rear fanged snake that moves quite fast and in one hand a camera. all in a days work:P.
