I was just talking with a friend the other day and this subject came up. I told him about a show I had seen back in the 1980's called Ring of Fire, that was about a couple of guys hiking to remote areas of Indonesia. In one episode, they were hiking through a remote jungle area of Borneo and surprised a large retic on the ground. It immediately shot up an adjacent tree trunk about a foot in diameter that was smooth without any limbs for probably the first 20 or 25 feet. Using a concertina motion, it coiled around the trunk with its tail and lower body, reached up to anchor its head and front part of it's body on another section of the trunk by coiling around it, then pulled up its back half and so on up the trunk. The remarkable thing was the speed at which this occurred. I would estimate the retic was at least 15 feet in length and was out of sight and into the canopy in about 10 seconds. It was pretty impressive for a python of that size..
