Diagnosis: body fairly elongate, its depth 12-14% TL at anal origin, covered with scales up to pelvic fins and nape and on part of unpaired fins. Pelvic fins very short, about 2% TL; preanal distance 43-47% TL. Scales very small, at least 50 rows between anal fin origin and base of dorsal fin, first appearing in late juveniles (10-11 cm TL); lateral line single, ventral. Vertebrae 103-107 (precaudal only 22). Colour: uniformly dark, without light markings, greyish-brown to bluish-black on lower part of head, gill membranes and margins of dorsal and anal fins. Size: to 70 cm TL, usually 40-55 cm.

Habitat: benthic on muddy bottoms at (491) 905-3,000 m, mostly at 1,000-1,800 m, with bottom temperatures below O °C ( - 0.6 to -1 .6 °C). Food: bottom crustaceans (isopods, amphipods), ophiurids, cephalopods. Reproduction: probably early autumn; eggs demersal, about 500; 7 mm diameter.

Distribution: Norwegian and Greenland seas, but not to south of the Faroes-Shetland Ridge. Elsewhere, to north of Spitsbergen, in northern part of Laptev, East Siberian and Chukchi seas (absent from Baffin; Bay) and North Canadian Arctic (85° 48' 26.8" N 110° 43' 39.3" W)(McAllister 1990)
