|Scientific Name:||Cruriraja durbanensis (von Bonde & Swart, 1923)|
|Red List Category & Criteria:||Data Deficient ver 3.1|
|Assessor(s):||Smale, M.J. & Pheeha, S.|
|Reviewer(s):||Cavanagh, R.D., Valenti, S.V. & Fowler, S.L. (Shark Red List Authority)|
This rare species, known only from two specimens, is a local endemic with at least part of its range in an area of high exploitation by the South African and Namibian trawl fishery centred on hake. Although there are no data indicating a decline, its limited distribution, large size and likely limiting life history traits make it vulnerable to fishing pressure. There is insufficient data to assess this species beyond Data Deficient at the present time, however the status of this rare endemic should be re-evaluated when data become available.
|Range Description:||Southeast Atlantic: known only from the holotype collected off Hondeklip Bay off the Northern Cape Province of South Africa (not from off KwaZulu-Natal on the east coast, as suggested by the name), and a paratype (locality and depth unknown). Not recorded from African research cruises along the west coast of southern Africa (Compagno et al. 1991).|
Native:South Africa (Marion-Prince Edward Is.)
|FAO Marine Fishing Areas:|
Atlantic – southeast

|Population:||A rare skate known only from two specimens. This southern African endemic may be more common than currently known in waters deeper than currently exploited or surveyed by research vessels.|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||C. durbanensis attains at least 31 cm TL and is known from depths of about 860 m (Hulley 1988).|
|Major Threat(s):||At least part of its range in an area of high exploitation by the South African and Namibian trawl fishery centred on hake. Although there are no data indicating a decline, its limited distribution, large size and likely limiting life history traits make it vulnerable to fishing pressure. May be impacted by deeper fisheries in the future.|
No specific measures in place. Specimens should be collected and studied. Like many deeper water species more information on biology, ecology and importance in fisheries are required to further assess status and any future conservation needs. Where taken, catches require monitoring, particularly as deepwater fisheries expand worldwide.
The development and implementation of management plans (national and/or regional e.g., under the FAO International Plan of Action for the Conservation and Management of Sharks: IPOA-Sharks) are required to facilitate the conservation and management of all chondrichthyan species in the region.
