Max length : 180 cm TL male/unsexed; (Ref. 7251); common length : 120 cm TL male/unsexed; (Ref. 4694); max. published weight: 27.9 kg (Ref. 40637)
Coloration greyish brown with many distinct spots on body and dorsal fin (Ref. 35388).
Northwest Atlantic: western Greenland and Nova Scotia in Canada to Massachusetts in USA and perhaps to New Jersey, USA (Ref. 7251). Northeast Atlantic: Spitsbergen southward to Scandinavian coasts (to about Bergen, also Iceland and south-eastern coasts of Greenland.
Inhabits offshore waters over soft bottoms, often with boulders, from 25-590 m, but most common from 100-400 m (Ref. 4694). Benthic (Ref. 58426). Feeds mainly on echinoderms, but also crustaceans, mollusks, fishes (Ref. 4694) and worms (Ref. 58426). In Barents sea, it reached at least 80 cm, age 9 years. Marketed fresh or as frozen fillets. Leather can be made of the skin (Ref. 35388).
