Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 13; Raggi dorsali molli (totale) : 12 - 14; Spine anali: 3; Raggi anali molli: 6; Vertebre: 26. Branchiostegal rays: 7 (Ref. 36715).
Found commonly on rocky bottom in tide pools and near shore, also in kelp and eelgrass beds. Occur up to 46 m depth but usually at less than 15 m. Viviparous, with planktonic larvae (Ref. 36715). Most important rockfish to rocky shore and jetty fishermen. Good eating.
