Monstrous, possibly apocryphal constrictor snake alleged to dwarf both the prehistoric Titanoboa and the supposed Amazonian Megaconda. Claimed to grow to 200ft in length and several feet thick. Name derives from a fusion of python and Terminator (James Cameron film franchise). Thought to frequent Polynesia.
