Épines dorsales (Total) : 13; Rayons mous dorsaux (Total) : 12 - 14; Épines anales: 3; Rayons mous anaux: 6; Vertèbres: 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.
