简单描述

背棘 (总数) : 0; 背的软条 (总数) : 109 - 118; 臀棘: 0; 臀鳍软条: 99 - 109; 脊椎骨: 118 - 126. This species is distinguished by the following: with scales covering the nape and the entire postorbital dorsal surface of the head (in adults 15.0 cm SL and larger): it differs from L. beringi in having higher counts of dorsal-fin ray (usually 111 or more), anal-fin ray (usually 100 or more), vertebral (usually 119 or more), and gill raker (usually 15 or more); differs from L. hubbsi in having 19-21 pectoral-fin rays (vs. 20-23), position of the first dorsal-fin
pterygiophore at the sixth or seventh interneural gap (vs. third), and color pattern, for it lacks narrow light bands extending onto dorsal fin and across nape; differs from the 'L. nakamurae group’’ (nakamurae, pectoralis, nishimurai) in having 4 postorbital pores (vs. 1 or 2), the posteriormost without a short tube; lower pectoral-fin lobe rounded, the tips of the rays rounded and the middle rays often branched, fin membrane not incised (vs. pointed, with rays pointed and unbranched, membrane moderately incised); scales often present on base of pectoral fin; light inverted V-shaped bands usually present on body (Ref. 80505).
尾部的不清楚地可与背鳍与臀鳍区别; 在中央中的胸鳍有凹槽的; 腹鳍小的.(参考文献 6885) 腹地的暗褐色的在背面上又蓝色的黑色; 在鳞片上的细突出的淡色斑点; 在背鳍上延伸的身体侧边上的 8 或 9个淡的纵带而且在身体下半部上传布或分开, 变成模糊或消失当成鱼时; 在胸鳍，腹鳍与臀鳍上的蓝色的黑色; 在嘴与鳃腔的衬里上的蓝色的黑色; 暗色到黑色的在腹膜上.(参考文献 6885)
Found on muddy bottoms (Ref. 2850). May be used as bait (Ref. 27436). Flesh considered firm and tasty but not esteemed (Ref. 27436).
栖息于泥底部了。 (参考文献 2850) 可能是当作鱼饵使用。 (参考文献 27436) 肉被认为是结实而好吃的但是不赞赏.(参考文献 27436)
