Maturity: Lm 25.8  range ? - ? cm
Max length : 60.0 cm TL mâle / non sexé; (Ref. 3397); common length : 25.0 cm TL mâle / non sexé; (Ref. 3397); poids max. publié: 0.00 g; âge max. reporté: 16 années (Ref. 108908)
Épines dorsales (Total) : 0; Rayons mous dorsaux (Total) : 85 - 94; Rayons mous anaux: 64 - 74. 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. Dorsal and anal fin with indefinite darker spots posteriorly.
Adults occur on soft bottoms. Depth range from 100-400 m (Ref. 06302) and from 288-700 m in the eastern Ionian Sea (Ref. 56504). Feed on small bottom-living fishes as well as squids and crustaceans (Ref. 4703). Spawning occurs in deep waters off Iceland and west of the British Isles (Ref. 35388).
