Ganjukos were sizable beings native to the planet Fenn, characterized by their beaks and dense, hairy pelts. These creatures were infamous for their tendency to suddenly engage in stampedes. Their beaks were highly valued, as they could be fashioned into costly daggers. Prior to the era of the Republic, they were dispersed to various planets within the Dufilvian sector and also to worlds in Bothan sector like Kothlis and Bothawui.
To conserve warmth in extremely cold environments, these beings possessed substantial layers of fat beneath a coat of dark, dense fur. Their cranial plates and beaks consisted of exceptionally tough cartilage, utilized for both offensive maneuvers and excavation in icy terrain. Retractable cartilage eyelids served to shield their eyes, and the creatures frequently favored auditory and olfactory senses over vision during combat.
