Hyraxes (from the Greek ὕραξ, hýrax, "shrewmouse"), also called dassies, are small, thickset, herbivorous mammals in the order Hyracoidea. Hyraxes are well-furred, rotund animals with short tails. Typically, they measure between 30 and 70 cm (12 and 28 in) long and weigh between 2 and 5 kg (4.4 and 11 lb). They are also superficially similar to pikas or rodents (especially marmots), but are more closely related to elephants and manatees. Five extant species are recognised the rock hyrax (Procavia capensis) and the yellow-spotted rock hyrax (Heterohyrax brucei), which both live on rock outcrops, including cliffs in Ethiopia and isolated granite outcrops called kopjes in southern Africa, the western tree hyrax (Dendrohyrax dorsalis), southern tree hyrax (D. arboreus), and eastern tree hyrax (D. validus). Their distribution is limited to Africa, except for Procavia capensis which is also found in the Middle East.
