Short description
Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
Ραχιαίες άκανθες (συνολικά) : 0; Μαλακές ραχιαίες ακτίνες (συνολικά) : 87 - 101; Εδρικές άκανθες: 0; Μαλακές εδρικές ακτίνες: 67 - 79; Σπόνδυλοι: 41 - 44. Dorsal origin over middle part of eye. Caudal longest in middle, ending in a broad 'V'. Pectoral fins large, bluntly pointed.
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).
