Xandank

Xandanks, often called crustacean cats, were dangerous insectoid creatures native to the lava world Mustafar. They were pack hunters that hunted their prey in well-coordinated teams.

The Xandank was one of the few known species in the galaxy that had both an exo- and endo-skeleton, making it very strong and extremely well armored.

At the time of the Clone Wars, a Jedi Knight owned a Xandank named Cobak. The beast was very loyal, it followed the Jedi's order to watch over his hidden belongings for almost two decades after the Jedi had to flee from attacking clone troopers due to Order 66.
