The Sher Kar was the supreme native predator on the planet Mustafar. They were scorpion-like and larger than humans, and was considered dangerous to them. Sher Kars had three pairs of legs, a mouth with a tongue and teeth, and a long speared tail. They were usually found deep in the nesting grounds of the tulrus, which was the Sher Kars' prey of choice.
This was the creature that was on the concept art for Revenge of the Sith.
