Common offshore, on soft bottoms (Ref. 2850). Young occur in shallow water, often at surface under drifting kelp (Ref. 2850). Viviparous, with planktonic larvae and pelagic juveniles (Ref. 36715, 34817). The biggest individuals are sometimes found in markets where the flesh is sold as rockfish fillet (Ref. 27436). Rarely caught by anglers (Ref. 27436).)
