[1] 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.
The eggs are laid in pairs and the growing young subsist entirely on the egg-yolk until they hatch.
It lives below the depth range at which fishing is normally undertaken but it may be caught as bycatch in some deep water trawling activities, and it may be threatened in the future by an expansion of deep-water fisheries.
