生态学
海洋; 淡水; 半咸淡水 礁区鱼类; 深度上下限 0 - 180 m (Ref. 37816), usually 10 - 70 m (Ref. 30573). 热带; 31°N - 33°S, 31°E - 128°W (Ref. 55)
Indo-Pacific: East Africa to the Marquesas and Line islands, north to the Ryukyu Islands, south to Australia. More common around oceanic islands than in continental areas.
印度-太平洋: 东非到马可萨斯岛与列岛群岛, 北至琉球群岛, 南至澳洲。 更普遍大洋性岛屿的周围超过在大陆的区域中。
Length at first maturity / 大小 / 重量 / 年龄
Maturity: Lm 42.9, range 39 - ? cm
Max length : 90.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 9987); common length : 76.0 cm SL 雄鱼/尚未辨别雌雄; (Ref. 37816); 最大体重: 12.5 kg (Ref. 4699); 最大年龄: 55 年 (Ref. 72420)
背棘 (总数): 10; 背的软条 (总数): 13-14; 臀棘 3; 臀鳍软条: 8. This species is distinguished by the following characters: moderately deep body, its greatest depth 2.4-2.9 in SL; distinct groove or pit from nostrils to the front of the eye; preopercular notch and knob moderately developed; vomerine tooth patch narrow crescentic, without a medial posterior extension; gill rakers of first gill arch 6-7 + 16 = 22-23 (including rudiments). Colour of body dark reddish-brown with faint dark stripes; young and some adults with two silvery-white spots on back; pectoral fins pink with dorsal edge prominently black; juveniles sometimes have caudal end of body and the tail white. mimicking Chromis damselfishes (Ref. 9821, 90102).
吻略微尖的。 头部的背面轮廓圆的。 眶前骨相当宽的; 它的宽度通常大于眼直径。 一个深沟或凹洞从鼻孔到眼睛前方。 前鳃盖骨凹槽与疖瘤适度发展的。 鳞片列背面斜向上升在侧联机面。 幼鱼与一些成鱼有二个银白色斑点背面。 大的成鱼大部份全红色.(参考文献 48635)
Adults inhabit coral reefs, including sheltered lagoons and outer reefs (Ref. 30573). Usually found singly, often adjacent to steep outer reef slopes, but occasionally found in groups (Ref. 9710). Feeds mainly on fishes, but also take shrimps, crabs, amphipods, stomatopods, gastropods and urochordates. Large fish from oceanic areas in the western Pacific are often ciguatoxic, e.g., in Tuvalu (Ref. 9513). Caught mainly with handlines and bottom longlines (Ref. 9821). Utilized fresh and dried-salted (Ref. 9987). Juveniles mimic Chromis damselfishes (Ref. 90102). Minimum depth reported taken from Ref. 128797.
栖息于珊瑚礁, 包括有掩蔽的泻湖与外海岩礁。 (参考文献 30573) 通常单独地发现, 时常邻近陡峭的外礁斜坡, 但是偶然形成鱼群.(参考文献 9710) 主要吃鱼, 也捕食虾，螃蟹，片脚类动物，口足目甲壳类，腹足动物与海鞘类。 在图瓦卢,来自西太平洋的海洋性地区的大的鱼时常是有西加毒的，例如。 (参考文献 9513) 生鲜使用与乾燥盐腌.(参考文献 9987) 在香港活鱼贩售。 (参考文献 27253)
