The Saw-toothed grank were native to the Gungan swamps of Naboo. They were a medium sized predator with sharp teeth and powerful jaws. Their main prey were shiros. Gungans found the taste of granks very appealing and would fry them. The toenails of granks were used to create Bongo engine parts, while their meat was a delicacy served in high-end restaurants. To hunt, they sensed vibrations through their hair from both the air and ground.
