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.

Oxalis natans
Water Sorrel

Importance:
This highly threatened species is one of the true aquatic species in Oxalis, but much of its original habitat has been lost to urbanisation. Interestingly, it is completely unrelated to the other aquatic species - the genome of this species may offer insights into its conservation, and also into the convergent evolution of an aquatic habit in South African Oxalis. It is Redlisted as Critically Rare.
