An apparently uncommon or rare little-known endemic skate (southern Namibia to Cape Point, South Africa). However, its known range (400 to 500 m, some records >700 m) includes depths below those of current commercial trawl fisheries, hence it is assessed as Least Concern. It is likely to be more common in areas deeper than those sampled to date, however, the situation should be monitored given its apparent limited range and the potential threat of expanding deepwater trawl fisheries in the region.
|Range Description:||Southeast Atlantic: Southwest of Walvis Bay and off Lüderitz, Namibia and from the Orange River to southwest of Cape Point, South Africa (Compagno et al. 1991).|
Native:Namibia; South Africa
|FAO Marine Fishing Areas:||
Atlantic – southeast

|Population:||An uncommon to rare skate, at least at the depths sampled to date.|
|Habitat and Ecology:||
A poorly known species of the continental slope. Smaller specimens appear to be found in waters of 400 to 500 m while larger specimens were from deeper than 700 m (Compagno et al. 1991).
Maximum size: attains about 64 cm total length (TL), 39 cm disc width (DW) (Hulley 1988).
|Major Threat(s):||Expansion of commercial trawling into deeper waters.|
|Conservation Actions:||Recommended conservation measures include studies on catch rates and life history characteristics.|
