Maturity: Lm ? range ? - ? cm
Max length : 41.0 cm TL mannelijk / geslacht onbekend; (Ref. 90102); common length : 30.0 cm TL mannelijk / geslacht onbekend; (Ref. 5450)
Dorsale stekels (totaal) : 8 - 9; Dorsale zachte stralen (totaal) : 20 - 23; Anale stekels: 3; Anale zachte stralen: 16 - 20. This species is distinguished by the following characters: D1 VII-VIII, D2 I,20-23 (usually 22 or 23); lobe of second dorsal fin filamentous in young, becoming shorter with age, in mature adults distinctly shorter than head length (larger than 25 cm fork length, height of second dorsal-fin lobe usually shorter than head length, and slightly to distinctly shorter than anal-fin lobe); A II + I,16-20; gill rakers including rudiments 5-8 + 15-19 = 21-27; straight part of lateral line with 16-20 scutes, and 31 to 50 total elements (including anterior scales); breast naked ventrally to distinctly behind origin of pelvic fins; laterally, naked area of breast typically extends diagonally to naked base of pectoral fins (rarely, naked areas of breast and pectoral-fin base interrupted laterally by a narrow band of scales); jaws with bands of villiform teeth, the bands widest anteriorly; in life, bluish green above, silvery grey below; sides with numerous, small yellow spots and a small black blotch on upper margin of opercle; second dorsal, anal, and caudal fins dusky, the latter sometimes yellowish; pectoral fins pale yellow; pelvic fins hyaline to pale grey (Ref. 9894); often with 5 diffuse dark bars (Ref. 90102).
Adults are found in deep coastal reefs and rarely inshore (Ref 3197). They are usually in small groups over sand bottoms near reefs (Ref. 90102).
