生物学特性     字汇 (例如 epibenthic)

A rare species (Ref. 26346) inhabiting continental slopes (Ref. 247). Usually mesopelagic although taken most often near the bottom (Ref. 10717). Its razor-edged lower teeth is used to attack and dismember large prey (Ref. 247). Ovoviviparous (Ref. 205). Utilized dried salted for human consumption and for fishmeal (Ref. 247).
