The area of occupancy of the White-bodied Catshark (Apristurus albisoma) is presumed to be very limited, being restricted to a narrow depth band on insular and seamount slopes in the Western South Pacific. It has only been reported from a few areas around New Caledonia and adjacent seamounts (Norfolk and Lord Howe Ridges) at depths of 935-1,564 m. However, there is very limited deepwater fishery activity within the geographic and depth range of this species, and it would generally find refuge outside the reach of those fisheries in place. The species is therefore assessed as Least Concern, with the caveat that this assessment be revisited if deepwater trawling was to expand or increase within its distribution.

|Habitat and Ecology:||A poorly known deepwater catshark occurring on insular and seamount slopes at depths of 935 to 1,564 m (Nakaya and Séret 1999). This species matures at 40 to 50 cm total length (TL) and reaches a maximum size of 60 cm TL (Nakaya and Séret 1999).|
|Use and Trade:||This species is not known to be utilized.|
The White-bodied Catshark is possibly a bycatch of deepwater fisheries, but is of no value and would be discarded; its depth range is largely outside of current fishing activities.
Within Australian waters current fishing effort is low around the Norfolk and Lord Howe Ridges, with only a small number of areas fished by a limited number of vessels, and so any impacts would be limited (Penney 2014, Penney and Curtotti 2014). New Caledonian deepwater fishing is generally limited to line fishing for deepwater snapper (Gontard and de Coudenhove 2013) with no deepwater trawling at present. The White-bodied Catshark is likely to find refuge outside the reach of any fishing activity.
