This species is distinguished by the following characters: body oval, flat and asymmetric; eyes located on right side of head, except in reversed individuals (Ref. 57416). Upper eye less than its own diameter from dorsal profile of head (Ref. 4710). Anterior nostril on blind side not enlarged (Ref. 4710, 57416), but surrounded by small rim (Ref. 57416). Its distance from front margin of head 1.5-1.9x in its distance from cleft of mouth; anterior nostril on eyed side with backward-pointing tube not or only barely reaching front border of lower eye (Ref. 4710). Preopercle covered by skin and opercle entirely scaled; mouth arched and inferior; dorsal and anal fins lacking spinous rays and united to caudal fin by well-developed membrane, but caudal peduncle distinct; dorsal fin originating on horizontal axis through upper eye; pectoral fin on eyed side asymmetrical, with 7-10 rays, and on blind side slightly shorter; straight part of lateral line visible, supratemporal part slightly arched above eyes; body covered with rectangular ctenoid scales (Ref. 57416).
Adults occur at a temperature range of 8.0-24.0°C (Ref. 4944). Usually solitary. They burrow into sandy and muddy bottoms. Retreat to deeper water during winter (Ref. 9988). Juveniles are found during the first 2 to 3 years in coastal nurseries (bays and nurseries) before migrating to deeper waters (Ref. 92286). Adults feed on worms, mollusks and small crustaceans at night. Waden sea is the most important nursery area. Batch spawner (Ref. 51846). Recruitment is very variable. Frequently found pelagically during spawning migrations (Ref. 35388). Marketed fresh and frozen; utilized steamed, fried, broiled, microwaved and baked (Ref. 9988).
Spawning takes place in shallow coastal waters at temperatures of 6 - 12°C. Reproduction starts after 3-5 years of age, when 25-30cm size is reached. Spawning happens mainly during the months of February-May (for example, off the coasts of Galicia), although in warmer areas
(such as the Mediterranean), it can occur at the beginning of the winter. Incubation lasts about 5 days (at 1 2°) and larval phase 35 days (at 18°C).
