These oversized hounds were bred to be fearless and relentless. Left to guard the Sith tombs of Korriban, they have sharp horns, long claws and savage teeth. They are unusually intelligent and seem capable of communicating with one another through unknown means.
It is said that the species was nonviolent and grazing before being corrupted by Sith alchemical experiments that awakened a latent part of their brains and changed them into unnatural abominations. Random mutations now occur that produce some tuk'ata that can live for centuries and grow to immense proportions.
