 The ghost catshark is a demersal (bottom-loving) species living just above the seabed in deep water in the Atlantic Ocean between 40° and 60° North.It is present on the continental slopes off Massachusetts in the United States and on the Porcupine Bank west of Ireland.A reported sighting of the deep-water catshark ("Apristurus profundorum") off Mauritania may have in fact been this species.
