Kurzbeschreibung
Bestimmungsschlüssel | Morphologie | Morphometrie
Rückenflossenstacheln (insgesamt) : 0; Rückenflossenweichstrahlen (insgesamt) : 109 - 118; Afterflossenstacheln: 0; Afterflossenweichstrahlen: 99 - 109; Wirbelzahl: 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).
Found on muddy bottoms (Ref. 2850). May be used as bait (Ref. 27436). Flesh considered firm and tasty but not esteemed (Ref. 27436).
