简单描述
型态特徵 | 形态测量图
背棘 (总数): 0; 背的软条 (总数): 52-61; 臀棘 0; 臀鳍软条: 26 - 33; 脊椎骨: 62 - 70. Number of lateral plicae 106-126, with a mean of 117.4. Best separated from A. dubius by the number of plicae singly or in combination with the number of vertebrae.
侧面皱摺 106-126 的数字, 具有一个平均的 117.4. 最好以脊椎骨的数字各别地或在组合与 A. dubius 分开了藉由皱摺的数字。
Found in shallow coastal waters as well as in protected bays and estuaries (Ref. 10198). Occurs in large schools and burrows in the sand at times to a depth of several inches. Feeds primarily on copepods (Ref. 27549).
