简单描述
型态特徵 | 形态测量图
背棘 (总数): 0; 背的软条 (总数): 90-107; 臀棘 0; 臀鳍软条: 70 - 90. Caudal sharply rounded but not readily distinguishable from dorsal and anal fins. Pelvic fins minute.
尾鳍非常圆的但是不轻易地可与背鳍与臀鳍区别。 腹鳍细小的。
Found on silty or sandy bottoms (Ref. 27436). Moves into shallow water at night to feed on marine worms, crustaceans, small bivalves, and brittle stars (Ref. 6885, 27436). Few live over 5 years (Ref. 6885). If used live as bait, it attracts large rockfishes, greenlings or codfishes (Ref. 27436). Flesh considered good but not esteemed (Ref. 27436).
栖息于了淤泥的或砂质底部.(参考文献 27436) 移入浅水区在晚上觅食海洋的蠕虫，甲壳动物，小的二枚贝与海星.(参考文献 6885,27436) 少数活超过 5 年。 (参考文献 6885) 如果当作活饵使用, 它吸引大的礁石鱼类， greenlings 或鳕鱼。 (参考文献 27436) 肉被认为是好的但是不赞赏.(参考文献 27436)
