Maw Luur
this immense creature was bio-engineered by the Yuuzhan Vong as a waste disposal system. A single maw luur could be placed aboard a worldship, where its vast capillary network absorbed waste materials and digested it, creating metals, nutrients, and air. The maw luur was often fitted into the living exoskeleton of the ship, providing life-sustaining nutrients to all parts of the ship. Many beings who encountered one of these creatures described it as a mating of a Sarlacc and atrash compactor.
