Morphology | Morphometrics
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).
