Comments: An oceanic species usually found offshore and far from land but sometimes occurring inshore (Ref. 9993, 43278, 58302).  Epi- and mesopelagic, with occasional near-bottom occurrences (Ref. 43278, 58302).  Although considered not dangerous to people, its powerful jaws, jaw muscles and teeth invite respect.  Flesh not appreciated and therefore the catch is usually discarded (Ref. 247); utilized for its large, squalene-rich liver (Ref. 9993).  Feeds on small pelagic bony fishes, squids and shrimps (Ref. 5578).  Ovoviviparous, embryos feeding on yolk sac and other ova produced by the mother (Ref. 50449).  With 4 young in a litter, born at 40 to 43 cm TL (Ref. 12288).  Maximum length for female given in Romanove et.al 1994 (Ref. 44781). Common bycatch of tuna longline fisheries, and occasionally tuna gillnet fisheries (Ref.58048).
