生态学
海洋 礁区鱼类; 深度上下限 ? - 20 m (Ref. 9710). 亞熱帶的; 10°S - 37°S, 143°E - 170°E (Ref. 55)
Western Pacific: restricted to the east coast of Australia and New Caledonia. The main Australian distribution is off southern Queensland between Cape Moreton (about 27°S) and the Capricorn Group(23°S). This species has been usually referred to as Lutjanus amabilis by previous authors.
西太平洋: 侷限於澳洲東岸與新加勒多尼亞了。 主要的澳洲分布是在莫瑞頓角 (大約 27個 °S) 與摩羯座群 (23個 °S) 之間的外海昆士蘭南部。 這種已經是被歸屬於通常的 Lutjanus amabilis 由先前的命名者。
Length at first maturity / 大小 / 重量 / 年龄
Maturity: Lm 25.0, range 20 - 30 cm
Max length : 50.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 55); common length : 30.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 55); 最大年龄: 40 年 (Ref. 2290)
背棘 (总数): 10; 背的软条 (总数): 14; 臀棘 3; 臀鳍软条: 8. Snout somewhat pointed. Preopercular notch and knob moderately well developed. Scale rows on back rising obliquely above lateral line. Generally pale blue-gray to whitish with suffusion of yellow on upper back. A prominent golden brown stripe, slightly narrower than the eye, runs laterally from the rear edge of the of the opercle to the caudal peduncle.
吻略微尖的。 前鳃盖骨凹槽与疖瘤一般发展良好的。 鳞片列背面斜向上升在侧联机面。 通常蓝灰色-灰色在上面的背面上微白色的具有黄色的红晕。 一条突出的金褐色斑纹, 些微窄于眼, 侧面地跑从后缘那对尾梗的鳃盖。
Adults mainly inhabit coral reefs. Sometimes forming large aggregations around rocky outcrops during daylight hours. They disperse to feed at night (Ref. 9710). Usually marketed fresh.
主要地居住于珊瑚礁。 有时在白天的时候岩石的露头周围形成大的群集。 分散觅食在晚上。 (参考文献 9710) 通常生鲜地在市场上销售。
