Biologia     Glossario (es. epibenthic)

A resident intertidal species with homing behavior (Ref. 32612). Can leave tide pools if aquatic conditions become inhospitable (Ref. 31184). Also found near or over rocks and in kelp beds up to about 30 m depth. Feed mainly on seaweed, occasionally takes invertebrates. Form dense schools in spring in kelp beds. Pelagic spawner (Ref. 56049). Breathe air when out of water (Ref. 31184). Considered an important game fish and may incidentally be caught in commercial fishing activities (Ref. 9310). Marketed fresh (Ref. 9310).
