简单描述
检索表 | 型态特徵 | 形态测量图
背棘 (总数) : 10 - 17; 臀棘: 0; 臀鳍软条: 16 - 22; 脊椎骨: 41 - 45. Silvery-white with black melanophores surrounding each scale on the dorsal two-thirds of the body. The dorsal half of the body is almost translucent.
银白色有在背部上围住每个鳞片身体中的三分之二的黑色的黑色素细胞。 背部一半的身体几乎半透明。
Usually occur in large schools near surface in open water, over dark sandy bottom (Ref. 35360). Well adapted to a life of heavy predation (Ref. 35360). Frequent skipping over the water surface is observed apparently in avoidance of predators (Ref. 35360).
通常大群出现近表面的在开放的水域中, 在深色的沙质底部之上.(参考文献 35360) 对重掠食的生活适应良好.(参考文献 35360) 在水面上的时常跳越在掠食者的逃避中被显然地观察。 (参考文献 35360)

Based on otolith data, these species spawn after their first winter and that only a small segment of the population lives through the second winter (Ref. 35360).北美洲: 出現在美國北卡羅萊那州只在湖 Waccamaw 中。

Generation time: 1.1 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
