Space Grazers
an alien lifeform, thought to be extinct for thousands of years before the Great Sith War. Aleema used Dark-Side illusions of them to try and deter the combined Jedi-Republic force that was sent to liberate the Empress Teta system. They were said to be space-faring, floating in the ether between the stars and eating any unsuspecting ships that passed near them. They resemble huge amoeba-like slugs with jellyfish-like tentacles hanging below them.
