Max length : 96.0 cm SL पुल्लिंग / अलिंग; (Ref. 31260)
ऐनल सौफट रेज़: 12 - 15; जानवरों की रीड़ का जोड़: 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).
