生態學
; 海洋 礁區魚類; 深度上下限 6 - 200 m (Ref. 2334). , preferred 28°C (Ref. 107945); 35°N - 33°S, 29°E - 180°E (Ref. 5222)
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.
Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm 20.0, range 19 - ? cm
Max length : 47.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 27266); common length : 35.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 5450); 最大體重: 1.4 kg (Ref. 27266); 最大年齡: 15 年 (Ref. 27352)
背棘 (總數): 11; 背的軟條 (總數): 15-17; 臀棘 3; 臀鰭軟條: 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).
