Brith were characterized by their large pectoral fins and the twin lobes that projected anteriorly on either side of their broad head. They had smooth skin, a broad, rectangular terminal mouth located at the front of the head, and a thin tail. Their two eyes were located laterally, while their gills were located ventrally. Their coloration was green on the dorsal side with purple margins, and mostly white on the ventral side.
Although the player cannot directly interact with them, brith can be seen flying above the plains of Dantooine in the video game Star Wars: Knights of the Old Republic. Although the name "brith" is never said in the game itself, it does, however, appear in the game files.
