Old Gloxix was a male styanax—a species of aquatic predator—that dwelled in the seas of the planet Tralus. 14 meters in length, Old Gloxix was scarred and stingerless, and he had a black-colored hide. In 496 BBY, he was brought down by the stabmen crews of three nagak canoes, and veteran stabmen later told tales of the hunt for Old Gloxix.
