Short description
Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt): 13; Mjukstrålar i ryggfenan (totalt): 12-14; Taggstrålar i analfenan 3; Mjukstrålar i analfenan: 6; Ryggkotor: 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.
