Max length : 99.0 cm TL Männchen/unbestimmt; (Ref. 2850); max. veröff. Gewicht: 14.0 kg (Ref. 27436); max. veröff. Alter: 13 Jahre (Ref. 56049)
Rückenflossenstacheln (insgesamt) : 8 - 12; Rückenflossenweichstrahlen (insgesamt) : 15 - 18; Afterflossenstacheln: 0; Afterflossenweichstrahlen: 11 - 13; Wirbelzahl: 35. Caudal fin barely rounded.
Inhabits rocky, sandy and muddy bottoms as well as kelp beds (Ref. 4925). Adults and juveniles feed on crustaceans, fishes and mollusks (Ref. 6885). Commonly captured by sport fishers (from shore, boats or piers) and by scuba divers (Ref. 2850). Flesh is good eating but eggs are poisonous and will make humans violently ill (Ref. 13513).
