Ongava Tented Camp or OTC is located at the foot of a dolomite hill, and since they are so many rocks ad crevices around, this is a paradise for rock hyraxes or dassies (Procavia capsiens) and dassie rats (Petomus typicusl)

At OTC you'll notice that while some dassies have a dark-near black dorsal spot, others have a whitish-yellowish one. This was describe in a scientific paper from 1966 in Journal of Mammalogy. If we believe this paper, the ones with a whitish dorsal spot would be a subspecies known as Kaokoveld rock dassie (Procavia capensis welwitschii) that is endemic to the region.
