Northern Sea. Reports from the Mediterranean Sea appear to be misidentifications of
P. flesus. It may have been present in some areas of the Mediterranean in the past, as a result of climatic changes related to the ice age, but at present times seem to be absent (Ref. 89040).

Upper side brown or greenish brown with irregularly distributed bright red or orange spots. The underside is white. Lateral line straight, slightly curved above pectoral fin. Dorsal fin reaching eye. More than 30 vertebrae.

Adults live on mixed bottoms, the older the deeper the occurrence; small individuals are usually seen on bathing beaches (Ref. 9988). Occurs on mud and sand bottom from a few meters down to about 100 m, at sea, estuaries and rarely entering freshwaters (Ref. 59043). Reported as resident intertidal species with homing behavior (Ref. 32612). Feed mainly on thin-shelled mollusks and polychaetes. Batch spawner (Ref. 51846). The most important flatfish for fisheries in Europe. Utilized fresh and frozen; eaten steamed, fried, boiled, microwaved and baked (Ref. 9988). Active at night in the very shallow water while day time is spent buried in the sand. Stationary for long periods, tagging experiments have shown that their spawning migrations can be long. Changes in the environmental conditions have been disadvantageous. Populations in Kattegat and Danish belts decreased in 1980's and early 1990's due to discharge of nutritive salts. Wadden sea is still an excellent nursery ground (Ref.35388).
Adult spawn when the temperature is around 6 °C (Ref. 4705).
