توصيف مختصر
كليدهاي شناسايي | ريخت شناسي | ريخت ستجي بوسيله انداره گيري
خارهاي باله پشتي (کل) : 3; شعاع نرم باله پشتي (کل) : 12 - 13; خارهاي باله مخرجي: 1; شعاع نرم باله مخرجي: 9; مهره ها: 27 - 29. This species is distinguished by the following characters: spined posterior and lower margins of the praeoperculum with an unspined notch in the angular part of it; insertion of ventral fins at the level of the vertical of the posterior margin of the pectoral fin insertion; upper jaw extends beyond the vertical of posterior eye margin; soft rays 12-13 in dorsal fin, 9-10 in anal fin; first branchial arch with 27-30 rakers; vertebrae 27-29; pyloric caeca 7 (Ref. 83719).
This was caught by non-closing fishing gear in water horizons of 1000-0 to 2000-0 m (Ref. 83719).
