Indo-Pacific: Red Sea and east coast of Africa to French Polynesia. In the western Pacific it ranges from southern Japan to southern Queensland and Lord Howe Island. Often confused with Epinephelus fuscoguttatus.
印度-太平洋: 紅海與非洲東岸到法屬玻里尼西亞。 在西太平洋中它範圍從日本南部到昆士蘭南部與羅得豪島。 時常與 棕點石斑魚〔Epinephelus fuscoguttatus〕 互相混淆。

簡短描述 檢索表 | 型態特徵 | 形態測量圖

背棘 (總數) : 11; 背的軟條 (總數) : 14 - 15; 臀棘: 3; 臀鰭軟條: 8. This species is distinguished by the following characters: body depth 2.7-3.1 in SL; preopercle rounded, finely serrate; upper edge of operculum distinctly convex; rear nostril diameter about twice that of anterior nostril; gill rakers of first gill arch 8-10 + 15-1= 24-27; dorsal-fin spines third or fourth longest, 2.7-3.3 in HL and distinctly shorter than longest dorsal-fin ray; 2-3 rows of teeth on midlateral part of lower jaw; front of jaws with inconspicuous fixed canines; body scales ctenoid in broad zone on side from beneath pectoral fin to caudal peduncle, the rest cycloid; caudal fin rounded; pectoral-fin rays 16-18, fin length 1.7-2.1 in HL; short pelvic fins, 1.9-2.4 in HL; lateral-line scales 47-52, in series 95-110. Colour of head, body, and fins pale brown, covered with small dark brown spots; upper half whitish, head and body with irregular dark blotches (more distinct on live specimens) superimposed over the dark spots; prominent black saddle blotch on caudal peduncle; dark spots extend all over head, including lower jaw, lips, branchiostegal membranes, gular area, and inside of mouth; numerous small white spots on fins (more distinct on live fish). a few on head and body; juveniles with a pair of blackish spots on each side of snout and a black spot at margin of second and third interspinous dorsal membranes (Ref. 39231, 89707, 90102).

生物學特性     字彙 (例如 epibenthic)

Often found in coral-rich areas of lagoon and outer reefs; in caves and large crevices to swim through (Ref. 48635). Most abundant around islands, particularly atolls. Usually in small schools but may be solitary (Ref 90102). Feeds mainly on crustaceans (portunid crabs) and fishes, sometimes on cephalopods and gastropods. In the Hong Kong live fish markets (Ref. 27253). This species is important in artisanal fisheries, but occasionally implicated in cases of ciguatera (frequently ciguatoxic in the Marshall Is., Ref. 37816). It is now uncommon at localities with heavy spearfishing, but popular in the aquaculture industry of Singapore, where it is known as 'marble grouper'. It is caught with hook-and-line, spear, and traps (Ref. 39231).

潟湖與外海岩礁的通常發現於珊瑚礁繁盛區域; 在洞穴與大的裂隙中游泳過.(參考文獻 48635) 最豐富的島周圍, 特別地環礁。 通常形成小的魚群。 主要吃甲殼動物 (梭子蟹) 與魚, 有時吃頭足類動與腹足動物。 在香港活魚販售。 (參考文獻 27253) 在馬紹爾群島中經常有西加毒。 (參考文獻 37816)
