Yozusk

Yozusks are very territorial beast that live on Dromund Kaas. They have rocky protrusions on their back and when the first Sith arrived on Dromund Kaas Yozusks were called "rock wardens" due to them. They have long arms and use them to dig up their prey which live underground. Yozusks also have rocky protrusions on their back. They rely primarily on their sense of smell in the darkness and are nocturnal. They are incredibly strong, and many young thrill-seekers like fighting the Yozusk's before they go after the much more stronger Gundarks.
