Actinopterygii (ray-finned fishes) > Pleuronectiformes
(Flatfishes) > Scophthalmidae
Etymology: Lepidorhombus: Greek, lepis = scale + Greek, rhombos = paralelogram (Ref. 45335). More on author: Risso.
Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; depth range 7 - 800 m (Ref. 6501). Temperate; 60°N - 26°N, 15°W - 36°E
Northeast Atlantic: British Isles south to Cape Bojador, West Sahara and the Mediterranean.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 40.0 cm SL male/unsexed; (Ref. 4703); common length : 20.0 cm TL male/unsexed; (Ref. 3397)
soft rays: 65 - 69. Dorsal fin origin closer to tip of snout than to anterior edge of eye. Dorsal and anal fins terminate just a little on the blind side of the caudal peduncle. Lateral line forms a distinct curve above the pectoral fin.
Inhabits soft bottoms (Ref. 6501).
Distinct pairing during breeding (Ref. 205). A determinate spawner (Ref. 72169).
