Length at first maturity / Size / Gewicht / Alter
Geschlechtsreife: Lm ?, range 28 - ? cm
Max length : 47.0 cm TL Männchen/unbestimmt; (Ref. 2334); common length : 25.0 cm TL Männchen/unbestimmt; (Ref. 9799)

This species is distinguished from Psammoperca datnioides by the following set of characters: Colouration: when alive, the head and body brownish dark and often golden in colour; pored lateral-line scales yellow-edged; and similar yellowish brown colour in preserved specimens; lower counts of pored lateral line scales 46-48; hind margin of maxilla reaching slightly short of hind margin of eye when mouth closed; tiny scales that are not seen with naked eye, but visible through binocular scope, on the posterior uppermost part of maxilla; pelvic-fin spine subequal to 4th dorsal spine; circumpeduncular scale 21-22; moderately lesser body depth, 32-36% (mean 36%) of SL; lower counts, 5½ / 7½-9½ scale rows above and below lateral line; gill rakers 7 (including 6 rudiments) + 1 + 11 (including 3 rudiments) = 19 (9 rudiments); last dorsal-fin spine / penultimate dorsal-fin spine 1.5-1.7 (Ref. 124584).
Body shape (shape guide): fusiform / normal; Cross section: compressed.
Inhabits rocky or coral reefs, frequently in weedy areas, usually in holes and crevices by day. Enters estuaries (Ref. 4833). Forages on fishes and crustaceans at night (Ref. 9710). Mainly marketed fresh. In Hong Kong sold live in fish markets (Ref. 27253).
