背棘 (总数) : 13 - 14; 背的软条 (总数) : 13 - 16; 臀棘: 3; 臀鳍软条: 7 - 9; 脊椎骨: 28 - 29. This species is distinguished by the following characters: body light yellow to greenish brown to gray, typically greenish brown, with orange flecks present on sides, distinctly light ventrally above anal-fin base and on ventral pectoral-fin rays; peritoneum light gray to jet black; strong symphyseal knob; extrinsic swimbladder muscle with a single section of striated muscle, lacking anterior fascia, otherwise of type I (a-z) of Hallacher (1974); lateral-line pores 43-54, scales 47-63; pectoral-fin rays 16-19; anal-fin rays 7-9; dorsal-fin rays 13-16; vertebrae total 28-29 (11-12 + 16-18) (Ref. 53613).
Collection depth between 6-370 m, deepest recorded depth at 675 m. Large adults common along the edge of the continental shelf at 100-300 m where the species is targeted for commercial use. Captured in the offshore trawl fishery. Males and females captured by trawl surveys vary widely in maturity during the summer (May-July) (Ref. 53613).
