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).
