Maturity: Lm ? range ? - ? cm
Max length : 68.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 49746); 最大體重: 3.2 kg (Ref. 7251)
Inhabit rocky or hard bottom and is a voracious eater. Food includes crustaceans, mollusks, sea urchins, fishes such as herring, sand lance and silver hake, and any bottom invertebrates that are available. When taken out of the water the belly becomes inflated so that when returned to the water they are unable to submerge. Adults attach their eggs near the base of a sponge to use as a spawning bed (Ref. 34819, 41075).
棲息於岩石或者堅硬的底部而且是一個貪婪的食客。 食物包括甲殼動物，軟體動物，海膽, 魚例如鯡魚, 沙子鎗矛與銀色的鱈魚，而且任何的底棲無脊椎動物那是有用的。 當帶離開水面，腹面變成膨脹所以當回到了水他們無法潛入水中。 成魚附上在海綿的基底附近的他們的卵使用作為一個產卵床.(參考文獻 34819,41075)
