морской батипелагический; пределы глубины 0 - 5100 m (Ref. 58018). Deep-water; 66°N - 27°S, 69°W - 1°W (Ref. 31260)
членистые (мягкие) лучи анального плавника: 12 - 15; позвонки: 77 - 81. In adults, head depth 23.2-26.8% of lower jaw length. Postorbital area 5.5-7.6% SL or 28.8-33.3% (less than 3 times smaller than HL). Rear edge of gill cover overlaps with the middle of the 4th vertebrae. Postadipose distance 6-7.4% SL (Ref. 31260).
Epimesopelagic species. Juveniles and fry observed exclusively within the central-circle current and its periphery; large adults caught mainly in boreal and sub-arctic waters. Feeds mainly on small and moderate-sized mesopelagic fishes; the largest Paralepis coregonoides and Arctozenus risso, had body length of 28-30 cm; a specimen caught from the southern region of Reykjanes Ridge had 12 individuals of Sebastes mentella ranging from 4.5-5 cm. Stomachs of those caught in the Mid-Atlantic Ridge have small squids (Ref. 31260).
