- "Yozusks were originally referred to as "rock wardens" by the Sith when they arrived on Dromund Kaas, because they nested in the cliffsides around the jungle and because of the hard, rocky protrusions on their backs. Though they are extremely territorial, they primarily feed on animals living beneath the ground, which they dig up with their long arms. They are nocturnal creatures and rely primarily on their sense of smell in the darkness. They are incredibly strong, and many young thrill-seekers cut their teeth fighting the yozusks before moving on to the larger, more powerful gundarks."
- ―In-game Codex (Bestiary)
To obtain the codex entry on Yozusks, you need to kill a Yozusk Platesmasher which can be found near the bottom of the map of Dromund Kaas; the Platesmasher is very close to the datacron in The Malignant Bog.
