Soresox
From Tardis Wiki, the free Doctor Who reference
The Soresox was a species of reptile native to the savannah of Flux. They looked like crocodiles made of stone, with crystalline eyes, stone teeth and mineral spit. They were very well camouflaged, nearly impossible to see in their natural habitat. Due to the harshness of their habitat, Soresox could wait for hundreds of years for food to arrive and could last as long without water.
When Flux was recreated on Planet 1, robotic versions of Soresox were added for effect. The Semblance of Draxyx was killed by one when they were reprogrammed into thinking that he was threatening Sebastiene. (PROSE: The Doctor Trap)
