Cave racer snake - Orthriophis taeniura ridleyi also called Elaphe taeniura ridleyi (Borneo)
It seems that it is also called Cave Dwelling Rat snake.
If you know which is the preferred denomination for this snake, please post a comment.
The cave racer (Elaphe taeniura) is the only snake which is adapted to spend its whole life in a cave, feeding exclusively on bats and swiftlets. It is non-venomous.
Spotted in Clearwater Cave in Gunung Mulu National Park (Borneo).
The Clearwater System is believed to be the largest interconnected cave system in the world by volume and the 9th longest cave in the world at 189 Km (as of 2011). For more photos, information and cave map, view my Clearwater cave photo series.
