Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 7; Dorsal soft rays (total): 21 - 22; Anal spines: 3; Anal soft rays: 16 - 18; Vertebrae: 25 - 26. This species is distinguished by the following characters: dorsal fin usually with 21-22 segmented rays; anal-fin modally with 17 segmented rays; relatively long lateral line,1.6-1.9 (mean=1.8) in SL; relatively well-developed scalation on the interorbital, suborbital and dentary; head length 2.4-2.6 in SL; peduncle depth 3.3-4.0 in HL (Ref. 116906).
