Tarentatek

Tarentateks were creatures of the Darkside who fed on the Force. They were thought to be hunted to extinction by the Jedi. But each time the Sith grew in power, they would appear again.

Darth Revan encountered the beasts on Korriban and Kashyyyk during the Jedi's campaign against Darth Malak. They seemed to appear on Darkside worlds, but there homeworld is unknown.
