South Horr
South Horr Singing Wells are wells dug by hand in dry river beds, sometimes very deep. Water is passed up using a chain of humans, singing as they mine the water.
The Rock Hyrax (Procavia capensis) is related to elephants and manatees. Modern hyraxes are members of the Procaviidae family, the only living family within the Hyracoidea. During the Eocene era, hyraxes of all sizes filled the plains of Africa: from a mouse-sized species to one the size of a small horse. Competition from bovids during the Miocene displaced these ancient hyraxes. While some evolved into the hyraxes we know today, others appear to have given rise to the elephant and sirenian (manatees and dugongs) families. Evidence supporting a common ancestor for hyraxes, elephants and the sirenians comes from some unusual shared characteristics. Like elephants, manatees, and dugongs, male hyraxes lack a scrotum and their testicles remain nestled in their abdominal cavity. The tusks of hyraxes develop from the incisor teeth, like elephant tusks; in most other tusked mammals, the tusks develop from the canine teeth. And hyraxes, like elephants, have flattened, hoof-like nails on the tips of their toes, rather than the curved claws seen on some other mammals.
