Feeds on large squids, gonostomatids, crustaceans, and may also bite circular plugs of tissue from large pelagic animals (wahoo, tuna, billfishes, cetaceans etc.) (Ref. 6577).Travels long vertical distances in excess of 2000 to 3000 m on a diel cycle. Presumably ovoviviparous. Tooth replacement: teeth are shed as a complete unit. Interconnection at the bases of individual tooth allows a whole row of teeth to move if one tooth is touched. This shark is reported to radiate light for as long as three hours after its death.
