生态学
海洋 礁区鱼类; 深度上下限 5 - 100 m (Ref. 55). 热带; 34°N - 35°S, 47°E - 180°E (Ref. 55)
Indo-West Pacific: Persian Gulf and Gulf of Oman to Fiji, north to southern Japan and Jeju Island, Korea (Ref. 114833), south to New South Wales, Australia (Ref. 114833) and New Caledonia (Ref. 86942). This species has been referred to as Lutjanus malabaricus (non Schneider) or Lutjanus altifrontalis by many recent authors. Occurrence in the Red Sea is a misidentification (Ref. 84159).
印度-西太平洋: 阿曼湾到东南亚, 北至日本南部, 南至澳洲北部。 这种已经被归属于 Lutjanus malabaricus(非 Schneider) 或 Lutjanus altifrontalis 由许多最近的命名者。 在红海的发生需要证实。 (参考文献 469,12541)
Length at first maturity / 大小 / 重量 / 年龄
Maturity: Lm 50.2, range 50 - ? cm
Max length : 81.6 cm FL 雄鱼/尚未辨别雌雄; (Ref. 5739); common length : 45.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 55); 最大年龄: 8 年 (Ref. 5739)
背棘 (总数) : 11; 背的软条 (总数) : 12 - 14; 臀棘: 3; 臀鳍软条: 8 - 9. Deep-bodied. Dorsal profile of head sloped. Length of upper jaw smaller than distance bet. base of last dorsal and anal rays. Preorbital bone usually narrower than eye diameter. Preopercular notch and knob poorly developed. Scale rows on back rising obliquely above lateral line. Juveniles with an oblique band extending from mouth to beginning of dorsal fin and a black spot at the caudal peduncle (Ref. 469). Body depth 2.5-3.0 in SL (Ref. 90102).
身体纵深。 头部的背面轮廓斜的。 比距离小的上颌的长度打赌。 最后背鳍与臀鳍鳍条的基底。 眶前骨通常窄于眼直径。 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。 稚鱼有在尾梗从嘴巴延伸到背鳍起点与一个黑色的斑点的一个斜纹。
Adults inhabit trawling grounds and reefs. They are present over shoals, rubble, corals, large epibenthos, hard or sandy mud substrates and offshore reefs (Ref. 6390). Usually in groups (Ref. 90102). Juveniles from about 2.5 cm length inhabit shallow waters over muddy substrates (Ref. 6390). Feed on a broad range of prey dominated by fish, and with small amounts of crustaceans, cephalopods and other benthic invertebrates (Ref. 6390). They forage mostly at night (Ref. 6390). They are marketed either gilled and gutted, whole as fillets, as fresh chilled or frozen product (Ref. 6390).
栖息于拖网渔场与礁。 它们出现浅滩，碎石，珊瑚，大的浅海底生物群，坚硬或沙的泥底部与外海礁石上。 (参考文献 6390) 稚鱼从大约栖息于在泥质底部上的浅水域的 2.5 公分长度。 (参考文献 6390) 捕食被鱼控制的大范围的猎物, 与和少量的甲壳动物, 头足类动物与其他的底栖无脊椎动物.(参考文献 6390) 他们大部份觅食在晚上。 (参考文献 6390) 他们被在市场上销售去除内脏与鳃, 如鱼排的全部, 如新鲜的冷冻或冷冻产品.(参考文献 6390)
Are serial batch spawners (Ref. 6390).印度-西太平洋: 阿曼湾到东南亚, 北至日本南部, 南至澳洲北部。 这种已经被归属于 Lutjanus malabaricus(非 Schneider) 或 Lutjanus altifrontalis 由许多最近的命名者。 在红海的发生需要证实。 (参考文献 469,12541)
