Northeast Pacific: Shumagin Islands in the western Gulf of Alaska to Ensenada, Baja California, Mexico. Possibly occurring in the Bering Sea (Ref. 6793).
Length at first maturity / サイズ / 重さ / 年齢
成熟: Lm 70.5, range 61 - 76 cm
Max length : 152 cm TL オス/雌雄の選別がない; (Ref. 2850); 最大公表体重: 59.1 kg (Ref. 40637); 最大記録サイズ: 25 年 (Ref. 55701)
背面の脊椎 (合計) : 24 - 27; 背鰭 (合計) : 21 - 24; 肛門の骨: 3; 臀鰭: 21 - 24; 脊つい: 55 - 59. Anal spines of adults buried in flesh, third spine closely applied to first ray (Ref. 6885). Head without scales; fleshy cirrus above each eye; large mouth; maxilla reaching almost to vertical from posterior margin of eye. Jaws with small pointed teeth interspersed with large fanglike teeth (Ref. 48751).
Body shape (shape guide): elongated.
Ranges from the intertidal to 475 m depth (Ref. 6793). Adults are found near rocks, inshore and to 427 m (Ref. 2850). Young occur on sand or mud bottom of bays and inshore areas (Ref. 2850). Both migratory and non-migratory populations exist (Ref. 6885). Adults feed mostly on other fishes but also take crustaceans, octopi and squid (Ref. 4925). Young feed on copepods and other small crustaceans (Ref. 6885). A very important sport and commercial species (Ref. 2850). The liver is rich in vitamin A (Ref. 6885). Marketed fresh and frozen; eaten steamed, fried, broiled, boiled, microwaved and baked (Ref. 9988). Has sharp teeth and gill rakers that can cut fingers if handled.
