背棘 (總數) : 0; 背的軟條 (總數) : 29 - 33; 臀鰭軟條: 27 - 30; 脊椎骨: 52 - 55. Lower jaw distinctly projecting beyond upper ones. Lacks a chin barbel. Dark lateral line that sharply curves over the pectoral fin and continues over whole body. No dark spot at pectoral fin base. Dorsal and anal fin interspaces short. Sensory canals with large pores on head. Body color is variable; dark dorsally, sharply distinguished from silver-gray sides and belly; the upper part of the body with yellow to orange streaks or blotches; the lateral line greenish. The fins uniformly dark except for the pelvic fins which are yellowish.
Body shape (shape guide): fusiform / normal; Cross section: circular.

Found in inshore waters but also down to 200 m depth, in areas with hard bottoms. Juveniles are pelagic, spending 2-3 years near the coast including rocky areas, kelp beds, sandy shores and estuaries (Ref. 1371, 58137, 89343, 89362). Juveniles may form schools with saithe (Pollachius virens) (Ref. 88187), and have also been found solitary and defending their feeding territory (Refs. 42174, 89363). Larger individuals move to the open sea and are often found around rocky areas at 40-100 m depth (Ref. 1371). Also observed around shipwrecks and oil platforms (Ref. 88187). Adults occur singly or in small dispersed shoals but is known to form dense shoals on spawning grounds (Ref. 89364). Suggested to undertake spawning migrations (Ref. 88171). Caught as bycatch in cod and saithe fisheries. Flesh is dry but of good flavor (Ref. 35388). Classified as a "hearing generalist" (89365); has also been found to produce sound. Juveniles have been reported to make repeated short grunts during competitive feeding and aggressive encounters (89366).
大洋性到大洋底棲性魚種, 大部份接近海岸硬底質上。 大部份捕食魚與附隨地吃頭足類動與甲殼動物 (蝦與螃蟹).(參考文獻 1371) 在鱈魚與 saithe 漁場中捕捉如誤捕了。 肉是乾但是好滋味.(參考文獻 35388)
