Indo-Pacific: Red Sea and the Persian Gulf to Natal, South Africa and east to Fiji, north to Japan, south to the Arafura Sea (Ref. 9819) and northern Australia. Recently recorded from Tonga (Ref. 53797). Appears to be absent from Micronesia, Polynesia, and most islands of the western Indian Ocean. Often confused with Epinephelus chlorostigma.

Max length : 47.0 cm TL αρσενικό/απροσδιόριστο; (Ref. 27266); common length : 35.0 cm TL αρσενικό/απροσδιόριστο; (Ref. 5450); μεγ. δημοσιευμένο βάρος: 1.4 kg (Ref. 27266); μεγ. αναφερόμενη ηλικία: 15 έτη (Ref. 27352)
Ραχιαίες άκανθες (συνολικά): 11; Μαλακές ραχιαίες ακτίνες (συνολικά): 15-17; Εδρικές άκανθες 3; Μαλακές εδρικές ακτίνες: 8. Characterized by grey to whitish color with numerous close-set orange to brown spots, becoming smaller and increase in number as growth increases; narrow white margin on tail; body scales ctenoid, cycloid scales on thorax and ventrally on abdomen; body with auxiliary scales; moderately elongate body, greatest depth 2.7-3.3 in SL; truncate or slightly emarginate caudal fin; pelvic fins 1.6-2.1 in head length (Ref. 90102).
Usually found in seagrass beds or on fine sediment bottoms near rocky reefs, dead coral, or alcyonarians (Ref. 5222), in shallow continental shelf waters (Ref. 27353). Juveniles are common at water depths to 80 m (Ref. 6390). Probably spawn during restricted periods and form aggregations when doing so (Ref. 27352). Eggs and early larvae are probably pelagic (Ref. 6390). Feed on fish and benthic invertebrates, primarily prawns and crabs (Ref. 4787, 27354).
