Marine; demersal; depth range 0 - 720 m (Ref. 114138). Boreal; 64°N - 34°N, 130°E - 118°W
North Pacific: between the middle Kuril Islands and Gulf of Alaska; including off the coast of Eastern Sakhalin, in the north of the Sea of Okhotsk, waters of Hokkaido, southern Kuril Is., and to the north up to Anadyr Bay. In the Sea of Japan, found once in northern Primorye and caught south of Moneron I. and in the open part of Peter the Great Bay (Ref. 114081). Southward range up to Redondo Beach, California (Ref.
Length at first maturity / Size / Weight / Age
Maturity: Lm 32.5  range ? - ? cm
Max length : 56.5 cm TL male/unsexed; (Ref. 56527); 35.0 cm SL (female); max. published weight: 2.0 kg (Ref. 56344); max. reported age: 15 years (Ref. 55701)
This species is found at the demersal zone and near surface over reefs and hard bottoms from intertidal zone to about 2.360 ft (719.8 m). It is preyed upon by other fishes, sea birds and marine mammals (Ref 114183).
Spawns twice a year (Ref. 28499). Eggs are deposited in rock crevices and are guarded by the male who continuously fans the egg mass with his pectoral fin until hatching (Ref. 28499), which occurs after 40-45 days (Ref. 27369).
