Although not based on genetic divergences, morphological differences were found among the 4 studied areas along Namibia and the South African coast (Leslie and Grant, 1990). The same authors therefore considered as more appropriate 3 units to be assessed and managed separately  Namibia (Maartens, 1999), W South Africa, and S South Africa (Glazer and Butterworth, 2011; Kirchner, 2011). Since that research, the DEFF (DEFF 2020) has indicated that there is likely no generic difference among these units. Here we examine the Cape monkfish, or Devil anglerfish, as one unit within South African waters (West and South Coast combined).
