1; Dorsal soft rays (total): 6 - 6; Anal soft rays: 16 - 18. Body
extremely elongate, predorsal distance 26-28% of SL; and dorsal
spine thin, weakly ossified and prolonged well beyond tip of first

rather swift channels of very large whitewater rivers. Can be
readily identified by the very long filament to the dorsal. Has
black colouring to the base of dorsal, pectoral, ventral and caudal
peduncle. Very striking if rare 'Dorad'.
