Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 99.0 cm TL male/unsexed; (Ref. 2850); max. published weight: 14.0 kg (Ref. 27436); max. reported age: 13 years (Ref. 56049)
Inhabits rocky, sandy and muddy bottoms as well as kelp beds (Ref. 4925). Adults and juveniles feed on crustaceans, fishes and mollusks (Ref. 6885).
