Tuk'ata were a species of shyrack-eating goat-like things that were particularly fearsome and deadly. Somewhat bizarrely, they appeared to be a hive-minded mammalian species, who took direction from a Queen-like beast. A number of tuk'ata nests had sprang up on Korriban by the time of the Jedi Civil War. Both Revan and the Jedi Exile had great fun exterminating these beasts; the ex-Dark Lord beat up on them in order to prove his "worthiness", while the exiled Jedi Knight just loved unleashing Hell on evil horned things.
