Coloration greyish brown with many distinct spots on body and dorsal fin (Ref. 35388).
Body shape (shape guide): elongated.
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).
Spawning happens between the months of September and January at 250 m depth. Females lay great egg bunches in nests built on the ground. The size of the eggs increases with the size of the female. Egg size 5-6 mm, larval length at hatching 21-24 mm.
