Occur on the shelf on rocky and rubble bottoms, as well as on sand around rocks. The young are close to shore while the adults occur offshore in the vicinity of the continental slope. Feed mainly on crustaceans, fish and cephalopods (Ref. 4781). Minimum depth reported taken from Ref. 27000. Maximum published weight 15 kg (Ref. 5377) and reported 16.42 kg (Miguel Cañizares (pers.comm. 7/2019).
生活於大陸棚岩石的之上與岩石的周圍碎石底部 , 以及沙子。 幼魚是接近海岸然而成魚在鄰近大陸斜坡出現外海。 主要吃甲殼動物，魚與頭足類動物。 (參考文獻 4781) 最小深度報告取自參考文獻 27000.
