Etymology: Stereolepis: Greek, stereos = dense + Greek,lepis = scale (Ref. 45335).
Eponymy: Gigas was a giant in Greek mythology, the child of Uranus and Gaea. The name is applied to taxa that are giants of their kind. (Ref. 128868), visit book page.

大小 / 重量 / 年齡
Maturity: Lm ? range ? - ? cm
Max length : 250 cm TL 雄魚/尚未辨別雌雄; (Ref. 40637); 最大體重: 255.6 kg (Ref. 4699); 最大年齡: 75 年 (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.)
生活於石質底部; 近岸, 外面海藻床而且沿著海峭壁.(參考文獻 2850) 大的標本通常發現深度超過 30 公尺, 在沙子上的較小與在海藻床中大部份從 12-21 公尺.(參考文獻 2850) 為產卵在中聚集夏天。 (參考文獻 2850) 活到至少 70 歲數年。 (參考文獻 2850)
