South African distribution: The Orange River (NC) to KZN.

Remarks: A very common coastal houndshark, it has a very wide range, occurring from South Africa to European Atlantic waters and into the Mediterranean Sea. Recent molecular research has revealed that at least two subpopulations exist for this species, one west to the west of Cape Agulhas and another to the east ( Maduna et al., 2016). During a long-term series of bottom trawl surveys by the F.R.S. Africana this species was never encountered at depths> 50 m ( Compagno et al., 1991). It is one of the most common species caught locally by shore anglers.

Conservation status: VU (2009).
