Gelagrubs, also known as Felucian ground beetles, were large insectine creatures that lived on the planet Felucia. Their preferred habitat was among the planet's towering mushroom forests. The gelagrub had a wide mouth above which were two vertically aligned eyes, and two rows of stubby legs endowed with adhesive characteristics that enabled it to climb steep inclines. The gelagrub had to eat constantly to maintain its natural sunscreen. They were easily domesticated creatures whose larval forms were used as mounts by Gossam colonists. The Alliance of Nations and later Multiversial Federation soldiers also used them as mounts during the Battle of Felucia in the First, Second and Third War..
