Eastern Atlantic around continental slopes from Iceland south to the Cape of Good Hope, Western Indian Ocean around Aldabra Islands, and western Pacific around Honshū, Japan, the Philippines, south-east Australia, and New Zealand.

The leafscale gulper shark lives near the bottom between 230 and 2,360 metres (750 and 7,740 ft), but usually below 1,000 metres (3,300 ft). Also occurs pelagically in much deeper water. It probably feeds on fish and cephalopods.
