Karoo Karoo The Karoo ( ; from a Khoikhoi word, possibly "garo" "desert") is a semi desert natural region of South Africa. No exact definition of what constitutes the Karoo is available, so its extent is also not precisely defined. The Karoo is partly defined by its topography, geology and climate, and above all, its low rainfall, arid air, cloudless skies, and extremes of heat and cold. The Karoo also hosted a well-preserved ecosystem hundreds of million years ago which is now represented by many fossils. The Karoo formed an almost impenetrable barrier to the interior from Cape Town, and the
Karoo north of the Great Karoo. Great locust swarms also frequently invaded or arose in the Great Karoo, and still occur from time to time today. The riverine rabbit, a critically endangered animal, lives exclusively in seasonal river basins and a very particular set of scrubland in the central semiarid region in the Karoo. It is hunted by falconiformes and Verreaux's eagles. Its numbers have been consistently lowering due to destruction of its habitat. They are unique relative to similar species through how they are polygamous and how each female can only produce one or two offspring per year. The introduction
