Etymology: Stereolepis: Greek, stereos = dense + Greek,lepis = scale (Ref. 45335).

Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; depth range 5 - 46 m (Ref. 2850). Subtropical; 41°N - 16°N
Eastern Pacific: Humboldt Bay in California, USA to Mexico. Northwest Pacific: Japan (Ref. 559).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 250 cm TL male/unsexed; (Ref. 40637); max. published weight: 255.6 kg (Ref. 4699); max. reported age: 75 years (Ref. 4563)
Occur on rock bottoms; near shore, outside kelp beds and along drop-offs (Ref. 2850). Large specimens usually found deeper than 30 m, small ones over sand and in kelp beds mostly from 12-21 m (Ref. 2850). Aggregate for spawning in summer (Ref. 2850). Pelagic spawners (Ref. 56049). Longevity of 90 to 100 years (Ref. 56049) stemmed from speculation on the age of a 557 lb fish caught in 1962, but the oldest age determined from otoliths of a 435 lb fish was 72 to75 years (Ref. 4563). Validated age so far is up to >50 years using bomb radiocarbon (A.H. Andrews, pers. comm.)
Pelagic spawner (Ref. 56049).
