Ραχιαίες άκανθες (συνολικά) : 13; Μαλακές ραχιαίες ακτίνες (συνολικά) : 12 - 14; Εδρικές άκανθες: 3; Μαλακές εδρικές ακτίνες: 6; Σπόνδυλοι: 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.
