Dorsale stekels (totaal) : 3; Dorsale zachte stralen (totaal) : 12 - 13; Anale stekels: 1; Anale zachte stralen: 9 - 10; Wervels: 27 - 29. 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).
