背鳍起点眼睛上方。 尾鳍圆的。 胸的小, 顿尖的。
Common in shallow water on soft, silty bottom. Moves into shallow water in summer and to deeper water in winter (Ref. 6885). Spawning adults exhibit north-south migrations (Ref. 6885). Feeds on chaetopod marine worms, young herring, shrimps, and sand dollars (Ref. 6885). A tasty food fish, sometimes marketed (Ref. 2850). Also used for mink food (Ref. 2850).
在柔软上常见于浅水区, 淤泥的底部。 在夏天与到较深的水域冬天时移入浅水区。 (参考文献 6885) 产卵的成鱼展现南北回游。 (参考文献 6885) 吃 chaetopod 海洋的蠕虫，幼鱼鲱鱼，虾与沙子元。 (参考文献 6885) 一个好吃的食用鱼, 有时在市场上销售。 (参考文献 2850) 也用来貂食物。 (参考文献 2850)
