简单描述 型态特徵 | 形态测量图

背棘 (总数): 8 - 9; 背的软条 (总数): 22-33; 臀棘 2-3; 臀鳍软条: 18 - 31; 脊椎骨: 22. Body varying from light bluish grey to dark brown, without blue lines. Outer part of pectoral fins abruptly white, the demarcation curved such that pale area is broadest on central part of fin. Least depth of caudal peduncle 3.1 to 3.3 times in head length. Maximum standard length about 33 cm (Ref 9808).
身体改变从淡的蓝灰色的到深褐色的, 没有蓝色的线。 胸鳍的外部部份醒目的白色, 划界弯曲了以致于灰白的区域在鳍的中央部份上宽。 尾柄的最少深度 3.1 到 3.3 倍头长。 最大的标准长度大约 33 公分 (参考文献 9808).

生物学特性     字汇 (例如 epibenthic)

Found off steep outer-reef escarpments. May be solitary but most commonly seen in small aggregations feeding on zooplankton well off the bottom.

发现外海的陡峭外围礁石陡坡。 可能是独居性但是最常在小群鱼群中见到离底部一段距离捕食浮游动物。
