Description Found on the continental and insular slopes, occasionally wandering onto continental shelves. Scanty information on feeding habits but probably eats bony fishes, elasmobranchs and invertebrates. Ovoviviparous, with 2 to 4 young in a litter. Size at birth between 70 and 85 cm. There is reason to believe that this shark may have oophagy or uterine cannibalism, but this remains to be proven. [details]
