Pythonator 

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.

The Pythonator could be capable of devouring whole elephants
