Environment: milieu / climate zone / depth range / distribution range
Ecology
Marine; brackish; demersal; oceanodromous (Ref. 51243); depth range 0 - 100 m (Ref. 35388), usually 10 - 20 m (Ref. 1371). Temperate; 68°N - 44°N, 11°W - 13°E
Northeast Atlantic: Trondheim on the Norwegian coast to the Bay of Biscay; also around the British Isles.
Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 30.0 cm TL male/unsexed; (Ref. 1371); common length : 20.0 cm TL male/unsexed; (Ref. 4645)
Dorsal spines (total): 0; Anal spines: 0. Head depressed. First dorsal fin poorly developed, with only three short rays. Color uniformly dark brown or bluish brown; the lips and the distal areas of all fins paler except for the pectorals.
Lives in coastal waters at shallow depths, generally from 10-20 m, more seldom from 75-100 m, on rocky bottom with seaweeds. Solitary and secretive, undertakes only limited local movements. Spawns from May to September at 50-70 m depth near the shore throughout its entire range. Feeds on sea stars, crustaceans, worms, mollusks and small fish (Ref. 1371).
