Dorsale stekels (totaal) : 9; Dorsale zachte stralen (totaal) : 25 - 30; Anale stekels: 3; Anale zachte stralen: 21 - 26; Wervels: 24. This species is distinguished by having the following characters: body subovate and compressed, becoming elongate-ovate and slightly subcylindrical with age; profile of head and nape slightly angular becoming more steep with age; mouth cleft of adults distinctly below level of eye; D1 VIII, D2 I,25-30, lobe of second dorsal fin shorter than head length; A II (2 detached spines) + I, 21-26 (rarely 25 or 26); gill rakers (including rudiments) 6-8 + 17-21 = 22-27; vertebrae 10 + 14; straight part of lateral line with 18-27 scales followed by 15-21 small scutes; breast naked ventrally to distinctly behind origin of pelvic fins; breast squamation variable laterally, either separated from naked base of pectoral fins by a moderate to very narrow band of scales or naked area of breast uninterrupted to naked base of pectoral fins; colour of adults iridescent blue-green above, silvery below; with numerous small gold or brassy spots mainly on dorsal half; large adult with 3 (to 5) irregular black blotches on flanks (sometimes very indistinct or absent, the first below dorsal-fin lobe, the second at inflection point of lateral line, and the third slightly anterior to midpoint of straight part of lateral line (Ref. 9894, 90102).
Adults prefer rocky and coral reef areas, but also found on offshore banks (Ref. 30573). They occur singly or in small to large schools (Ref. 9710, 48635, 90102). They feed on small invertebrates and fishes (Ref. 5213).
