This species is distinguished by the following characters: spinulated (without gap) posterior and lower edges of praeoperculum; insertion of ventral fins behind the vertical of posterior edge of pectoral fin insertion; upper jaw extends beyond the vertical of posterior eye edge; soft rays in dorsal fin 12-13, in anal fin 9-10; rakers at first gill arch 28-30; vertebrae 27-29; pyloric caeca 6 (Ref. 83717).
Oviparous, with planktonic eggs and larvae (Ref. 36655). There is significant morphological variation between populations (Ref. 4241).
