Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm ?, range 16 - ? cm
Max length : 52.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 1238); common length : 22.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 5450); 最大體重: 2.0 kg (Ref. 30874)
背棘 (總數): 11; 背的軟條 (總數): 15-17; 臀棘 3; 臀鰭軟條: 8. This species is distinguished by the following characters: body depth 2.8-3.3 in SL (for specimens 10-26 cm SL); head length 2.3-2.6 in SL; flat interorbital area, convex dorsal head profile; snout length 4.3-5.1 in HL; preopercle rounded, rear edge serrate, with lower most serrae slightly enlarged; upper edge of operculum straight; midlateral part of lower jaw with 2-4 rows of teeth; gill rakers of first gill arch 6-8 + 15-17; pyloric caeca 10-16; caudal fin slightly to moderately rounded (Central-Pacific often with truncate caudal fins); ctenoid scales on body except cycloid anterodorsally above lateral line and on thorax and ventrally on abdomen, with numerous auxiliary scales; nape and dorsoposterior part of head densely covered with minute auxiliary scales; lateral-line scales 49-75. Colour variable, ranging from pale greenish grey to pale reddish yellow to scarlet; body often with 5 or 6 faint dark bars, the last on peduncle; body scales (except ventrally) with pale centre and dark rear margin, producing a faint checked pattern; the outer triangular part of interspinous membranes of dorsal fin black (dark red in fish from Western Australia and in some specimens from deep water), with pale yellow or white spot behind tip of each spine (Ref. 39231, 89707, 90102).
Common in outer reef slopes at depths below 15 m, also occurs in protected bays and lagoons as shallow as 4 m. May also be found down to a depth of 160 m. At Madagascar it feeds night and day on brachyuran crabs, fishes, shrimps, and galatheid crabs (Ref. 6774). In Kenyan waters it feeds on crabs, stomatopods, fishes, ophiuroids, and octopus (Ref. 6448). In the Red Sea, mostly fishes and some crustaceans (mainly crabs) are consumed (Ref. 6699). Readily caught with hook-and-line, spear, traps, and gill nets (Ref. 39231)..
常見於外礁斜坡在深度在 15 公尺之下, 也出現於遮蔽的內灣與潟湖淺至 4 公尺中。 可能也被發現於向下至深度 160 公尺。 在馬達加斯加它在日間與夜間捕食十足目螃蟹，魚，蝦與鎧甲蝦科螃蟹。 (參考文獻 6774) 在肯亞水域中它吃螃蟹，口足目甲殼類，魚，陽燧足與章魚。 (參考文獻 6448) 在紅海，大部份魚與一些甲殼動物 (主要地螃蟹) 被消費。 (參考文獻 6699)
Life cycle and mating behavior
成熟度 | 繁殖 | 產卵場 | 卵 | 孕卵數 | 仔魚
This species exhibits a combination of simultaneous and sequential hermaphroditism. Smaller individuals within a social group are simultaneous hermaphrodites, while the largest often lose female function and reproduce exclusively as a male (Ref. 103751).印度-太平洋: 紅海到南非與向東至皮特凱恩島群,北至日本與韓國, 南至阿拉弗拉海 (參考文獻 9819) ，昆士蘭南部 (澳洲) 與羅得豪島。
