Justification: This catshark is known from occasional captures in deepsea exploratory trawls (in 700 to 1,200 m), becoming most abundant > 800 m. It is known to occur to 2,000 m or more. In southern Africa there are currently no deepsea trawl fisheries. In the North Atlantic, this species is possibly caught as a bycatch in deepwater trawl fisheries, but these could be other Apristurus species. A careful examination of North Atlantic A. cf. microps should be compared to southern African forms. Future expansion of deepwater fisheries could pose a threat to this poorly known species, however, at present much of its range is below the depth of fishing activities and it is considered to be Least Concern. |

| Habitat and Ecology: |
A benthic catshark of the continental slope, found on or near the bottom at depths of 700 to 2,000 m. South African specimens have been collected on soft bottom between 700 to 1,200 m. This species is also known to migrate off the bottom to feed on midwater prey items. Newborns, as known with other Apristurus species, may inhabit the midwater column until they start to mature whereupon they assume a more demersal lifestyle.
Size at maturity: approx. 50 cm total length (TL) (both male and female). Maximum size: 61 cm TL (males); 54 cm TL (females). |
| Systems: | Marine |
| Major Threat(s): | Possibly caught and discarded as bycatch by deepwater trawl fisheries, particularly in the North Atlantic. Expansion of deepwater fisheries may pose a threat to this species in the future, but at present most of its depth range is outside the reach of fisheries in its area of occupancy. |
| Conservation Actions: | None in effect or proposed at this time. |
