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).
The majority (50-70%) are males up to 50 cm length, transforming into females thereafter (Ref. 4781). Also Ref. 28504.
