Coohas were non-flying, carnivorous avians that originated on Gandeid IV, which is a temperate planet with low gravity located in the Gandeid system. These creatures could grow as tall as one and a half meters, and their bodies were covered with feathers. Their bodies were lanky, with a thin neck connecting to a head large in proportion. Their beaks contained small, sharp teeth. The Coohas possessed two slender wings, each terminating in a lengthy, pointed talon, along with two extended, narrow legs, each ending in a foot with two toes and talons.
The cooha's main food source was the flightless young of the noli, a species whose adult forms possessed strong beaks and claws. The Cooha utilized its slashing teeth as a defensive measure against adult noli when attacking their nests. Wilek Nereus, the Imperial governor of Bakura and a collector of predatory animal teeth, had cooha teeth in his collection.
