Western Pacific: southeastern Honshu in Japan, New South Wales in Australia, New Zealand, and Torres Island in Vanuatu.
Found on the uppermost continental and insular slopes, and probably the outer continental-insular shelves (Ref. 31367). Probably feeds on bottom fishes and some invertebrates (Ref. 247). Ovoviviparous (Ref. 205), with 10 pups in a litter (Ref. 247). Although not utilized commercially, the liver is relatively high in squalene oil (Ref. 6871).
