Morphology | Morphometrics
Eastern Pacific: Bering Sea coast of Alaska to Islas Los Coronados, northern Baja California, Mexico.
Adults are found on sand bottom (Ref. 2850), usually in deep water (Ref. 9988). Feed on invertebrates and bottom fishes (Ref. 6885). Livers of large individuals are a rich source of vitamin A (Ref. 6885). Marketed fresh or as frozen fillets (Ref. 2850). Eaten steamed, fried, micro-waved and baked (Ref. 9988). Generally regarded as the premium Pacific coast sole (Ref. 9988).
