Kalahari Basin Kalahari Basin The Kalahari Basin or Kalahari Depression is a large lowland area covering over 2.5 million km covering most of Botswana and parts of Namibia, South Africa, Angola, Zambia, and Zimbabwe. The outstanding physical feature in the basin, and occupying the centre, is the large Kalahari Desert. The city Windhoek is situated in the Kalahari Basin. Despite its aridity, the Kalahari Basin supports a variety of fauna and flora on soils known as Kalahari sands.

Desert pupfish finished spawning, she will flee in a "panicky" style with the male in pursuit. This chase lasts for about 5 minutes before the male swims to the bottom and both fish begin foraging. "C. macularius" are euryhaline and eurythermal, tolerating temperatures between approximately 4º and 45 °C and salinities ranging from 0 to 70 parts per thousand, exceeding the tolerances of virtually all other freshwater fish. The desert pupfish can also survive dissolved-oxygen concentrations as low as 0.13 ppm. The desert pupfish has been noted to be more abundant in environments with high vegetative cover, pH and salinity, and low
