Environment: milieu / climate zone / depth range / distribution range
Ecología
marino batipelágico; rango de profundidad 0 - 5100 m (Ref. 58018). Deep-water; 66°N - 27°S, 69°W - 1°W (Ref. 31260)
North Atlantic: from Canada (Ref. 5951), Greenland and Davis Strait, to Madeira I. and Canary Is. (Ref. 31260).
Tamaño / Peso / Age
Maturity: Lm ? range ? - ? cm
Max length : 96.0 cm SL macho / no sexado; (Ref. 31260)
Radios blandos anales: 12 - 15; Vértebra: 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).
