Length at first maturity / Size / Gewicht / Alter
Maturity: Lm 18.7, range 17 - 23 cm
Max length : 90.0 cm SL Männchen/unbestimmt; (Ref. 4781); common length : 50.0 cm SL Männchen/unbestimmt; (Ref. 4781); max. veröff. Gewicht: 11.6 kg (Ref. 40637)
Generally found in hard bottoms (rocks and rubble), the older individuals in the deeper part of the range, the young in inshore areas. Feed mainly on bivalves and also on crustaceans and fish. Sexual maturity at 2 years old. Spawning migration occurs parallel to the coast with intermittent spawning between spring and autumn over soft bottoms in shallow waters (Ref. 3688).

A different diagnosis of sexual pattern may arise for this species brought about by geographical variations (Ref. 103751). Also Ref. 41163.
