Importance:
The Orange river mudfish is a freshwater species endemic to southern Africa. Human activities, such as inter-basin water transfers, have facilitated hybridisation with Moggel (Labeo umbratus). Genomic data are essential to clarify its phylogenetic placement and assess the extent of hybridisation. It is listed as Least Concern on the IUCN Red List. Labeo capensis is an occasional angling species, and it is also used in ecological and physiological research. Additionally, it holds potential as a commercial species in large impoundments.

Arctocephalus pusillus pusillus
Cape Fur Seal

Importance:
The Cape fur seal is a marine apex predator that plays a critical role in maintaining a healthy marine ecosystem. It feeds on fish such as sardines and pilchards and is therefore competition with local, economically important fisheries. In Namibia, annual sealing yields meat, blubber and fur, which are then sold commercially, further contributing to the species' economic importance.
