Kalahari Craton Kalahari Craton The Kalahari Craton is a craton, an old and stable part of the continental lithosphere, that occupies large portions of South Africa, Botswana, Namibia and Zimbabwe. It consists of two cratons separated by the Limpopo Belt: the larger Kaapvaal Craton to the south and the smaller Zimbabwe Craton to the north. The Namaqua Belt is the southern margin of the Kaapvaal Craton. Parts of the Kalahari Craton are now located in East (the Grunehogna Craton) and West Antarctica (Haag Nunataks) and the Falkland Islands. The name was first introduced by .

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
