Environment: milieu / climate zone / depth range / distribution range
Écologie
marin démersal; océanodrome (Ref. 51243); profondeur 1 - 600 m (Ref. 58426), usually 18 - 110 m (Ref. 7135). Temperate; 82°N - 40°N, 75°W - 61°E (Ref. 119696)
Northeast Atlantic: Spitsbergen southward to White Sea, Scandinavian coasts, North Sea, the British Isles, to the Northen part of Bay of Biscaye, also Iceland and south-eastern coasts of Greenland (Ref.. 57932). Northwest Atlantic: southern Labrador in Canada and western Greenland to Cape Cod in Massachusetts, USA; rarely to New Jersey, USA (Ref. 7251). Elsewhere in the Baltic Sea and Mediterranean from Ref. 57932 should be regarded as questionable, as stray at most, until original reports are cheked (see Ref. 119696).
Length at first maturity / Taille / Poids / Âge
Maturity: Lm 55.0, range 50 - 60 cm
Max length : 150 cm TL mâle / non sexé; (Ref. 7251); poids max. publié: 23.6 kg (Ref. 40637)
Ground color usually greyish-green but almost black or reddish -brown. Body with 10-15 transverse, dark bars extended to the dorsal fin (Ref. 35388).
Inhabit rocky bottoms, sometimes over sand or mud, from 1-500 m (Ref. 9988). Benthic (Ref. 58426). Feeds on fishes (Ref. 58426), hard-shelled mollusks, crabs, lobsters, sea urchins and other echinoderms. Solitary in habit (Ref. 9988). Marketed fresh and frozen; eaten steamed, fried, broiled, boiled, microwaved and baked (Ref. 9988).
Males guard a clutch of eggs right up to the time of hatching (Ref. 6407). During brood protection, the male hardly feeds (Ref. 6407).
