May be found near the surface or off the bottom, generally over shallow reefs, but also around kelp and over deep reefs (Ref. 2850). Juveniles are pelagic (Ref. 36715). Form schools, sometimes with other rockfishes (Ref. 2850). Feed mainly on krill (Ref. 2850), but also on tunicates, jellyfishes and fishes (Ref. 6885). Viviparous, with planktonic larvae (Ref. 36715). Young are important prey for fishes and other marine vertebrates (Ref. 2850).
