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).
表中大洋性的種。 稚魚與魚苗專門地在中央-圓圈水流與它的外圍裡面觀察; 捕捉的大的成魚主要在北方生物帶與子北極的水域。 主要吃小的與中等大小的中層帶魚; 最大的 魣蜥魚〔Paralepis coregonoides〕 與 Arctozenus risso,有了 28-30 公分的體長; 一件標本捕捉了從 Reykjanes 脊的區域南部有被範圍從 4.5-5 公分的 Sebastes mentella 的 12個個體。 被在中大西洋脊捕獲的那些的腹部有小的烏賊。 (參考文獻 31260)
