Gairks, predators of the water, inhabited Ansion. These creatures, adapted to aquatic life with gills, possessed warty green hides and enormous, suction-generating mouths capable of engulfing a Human whole. Gairks had the ability to merge their oral cavities, amplifying the suction force they produced.
During 22 BBY, Jedi Padawans Barriss Offee together with Anakin Skywalker encountered a group of these river-dwelling gairks during their mission to Ansion. Nevertheless, the youthful Jedi managed to break free from the intense suction vortex created by the combined mouths of the gairks and escape unharmed.
