Western Pacific: Japan to Australia. Unknown from the Indian Ocean except for the Andaman Islands record (as Serranus merra). Unreported from islands of Micronesia, Melanesia and central Pacific. Often misidentified as Epinephelus macrospilos or Epinephelus hexagonatus.
西太平洋: 日本到澳洲。 不知道是否從印度洋除了安達曼群島記錄。 (如 Serranus merra) 沒有紀錄來自密克羅尼西亞,美拉尼西亞與中太平洋的島了。 時常被誤鑑成 大斑石斑魚〔Epinephelus macrospilos〕 六角石斑魚〔Epinephelus hexagonatus〕

简单描述 型态特徵 | 形态测量图

背棘 (总数): 11; 背的软条 (总数): 16-18; 臀棘 3; 臀鳍软条: 8. Distinguished by the following characteristics: whitish color; head, body and fins with numerous large close-set hexagonal to roundish dark brown to blackish spots; ctenoid body scales except cycloid dorsoanteriorly above lateral line, on thorax and abdomen; body with auxiliary scales; greatest depth of body 2.7-3.2 in SL; rounded caudal fin; pelvic fins, 1.7-2.1 in head length (Ref. 90102); head length 2.3-2.6 times in SL; evenly curved dorsal head profile; snout subequal to eye diameter, snout length 4.6-5.3 times in HL; rounded preopercle or subangular; upper edge of operculum almost straight; posterior nostril diameter about twice that of anterior nostrils; maxilla reaches to or past vertical at rear edge of eye; 2-3 rows of teeth on midlateral part of lower jaw; lower jaw barely projecting in front of upper jaw (Ref. 89707).

生物学特性     字汇 (例如 epibenthic)

Inhabits inshore silty reefs; there are no records from depths greater than 50 m. Feeds on shrimps, small fishes, worms and crabs (Ref. 89707). The enlarged fleshy pectoral fins appear to have resulted from its habit of sitting on the substrate. Solitary (Ref 90102).

栖息于近海淤泥的礁; 有没有来自深度大于 50 公尺的纪录。 吃甲壳动物,鱼,与蠕虫。 增大的肉质胸鳍似乎起因于它停留在底部上的习惯。
