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).
表中大洋性的种。 稚鱼与鱼苗专门地在中央-圆圈水流与它的外围里面观察; 捕捉的大的成鱼主要在北方生物带与子北极的水域。 主要吃小的与中等大小的中层带鱼; 最大的 魣蜥鱼［Paralepis coregonoides］ 与 Arctozenus risso,有了 28-30 公分的体长; 一件标本捕捉了从 Reykjanes 脊的区域南部有被范围从 4.5-5 公分的 Sebastes mentella 的 12个个体。 被在中大西洋脊捕获的那些的腹部有小的乌贼。 (参考文献 31260)
