Etymology: Lutjanus:Malay, ikan lutjan, name of a fish. More on authors: Bloch & Schneider.
Environment: milieu / climate zone / depth range / distribution range 生态学
Indo-West Pacific: Persian Gulf and Arabian Sea to Fiji, north to southern Japan, south to Australia. This species has been frequently misidentified as Lutjanus sanguineus (Ref. 55). There are unsubstantiated reports of this species from off East Africa. 印度-西太平洋: 波斯灣與阿拉伯海到斐濟, 北至日本南部, 南至澳洲。 這種曾經時常被誤鑑成 Lutjanus sanguineus 。 (參考文獻 55) 有來自外海的東非的這種的未證實的報告。
Length at first maturity / 大小 / 重量 / 年龄
Maturity: Lm57.6, range 54 - ? cm Max length : 100.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 55); common length : 50.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 55); 最大体重: 7.9 kg (Ref. 4699); 最大年龄: 31 年 (Ref. 46527)
背棘 (总数) : 11; 背的软条 (总数) : 12 - 14; 臀棘: 3; 臀鳍软条: 8 - 9. This species is distinguished by the following characters: body relatively deep; greatest depth 2.2-2.8 in SL; mouth large, maxilla length about equal to distance between bases of
last dorsal- and anal-fin rays; preopercular notch and knob poorly developed; vomerine tooth patch crescentic or triangular, without a medial posterior extension; gill rakers of first gill arch 4-7 + 12-14 = 18-20 (including rudiments); caudal fin truncate. Colour of back and sides red or red-orange, lighter on lower parts; fins reddish; juveniles with a broad, oblique band of brown or black from upper jaw to beginning of dorsal fin, and a prominent black band across caudal peduncle with a pearly white anterior border, similar to L. timorensis but without the black pectoral-fin axil; young also with a series of narrow reddish horizontal lines (sometimes absent) on sides (Ref. 9821, 90102).
头部的背面轮廓非常陡峭。 眶前骨比眼直径宽许多。 前鳃盖骨凹槽与疖瘤发展不良的。 鳞片列背面斜向上升在侧联机面。 稚鱼有宽，褐色或黑色的斜纹, 从上颌到背鳍起点; 一条突出的黑色条纹横越尾梗具有一个珍珠色到白色的边缘。 在侧边上幼鱼有水平线。 附注: (TL, 公分)=0.28+1.26;(SL, 公分) n=1034.(参考文献 1450)
Adults inhabit both coastal and offshore reefs. They tend to be associated with sponge and gorgonian-dominated habitats on the North West Shelf (Ref. 28006), and hard mud areas of the Arafura Sea. In Australia, they frequently form mixed shoals with L. erythropterus. Juveniles tend to inhabit shallow inshore waters and larger fish live in deeper waters (Ref. 27260, 27264). Juveniles also occur in mangrove areas and seagrass beds (Ref. 128523). Feed mainly on fishes, with small amounts of benthic crustaceans, cephalopods and other benthic invertebrates (Ref. 6390). They forage mostly at night (Ref. 6390). Caught mainly with handlines, bottom longlines, and bottom trawls (Ref. 9821). Marketed fresh, dried-salted (Ref. 55) and frozen (Ref. 9987).
