Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 0; Dorsal soft rays (total): 11; Anal spines: 0; Anal soft rays: 8 - 10; Vertebrae: 42 - 44. Second and third dorsal fin rays very elongated, prolonged filamentously, extending when depressed well beyond adipose fin in males, not quite reaching adipose fin in females (Ref. 49923). Sexually dimorphic in dorsal and caudal fin coloration: dorsal fin with a black upper margin broader in males than in females; caudal fin white with a black posterior margin on each lobe in males, black margin absent in females (Ref. 49923).
