A mesopelagic species, found primarily below 200 m depth (Ref. 36655). All studied specimens were reported to have been sampled by nonclosing gears from the depth of more than 2000 m that one cannot conclude about the exact sampling depth and the depth range of this species; notably, larger specimens occur deeper than young ones (Ref. 117119). Oviparous, with planktonic eggs and larvae (Ref. 36655).
海洋中層魚種, 主要地在 200 公尺深之下發現。 (參考文獻 36655) 卵生的, 卵與仔魚為浮游性.(參考文獻 36655)
