Hyraxes (from Ancient Greek ὕραξ hýrax 'shrew-mouse'), also called dassies,[1][2] are small, stout, herbivorous mammals in the order Hyracoidea. Hyraxes are well-furred, rotund animals with short tails.[3] Modern hyraxes are typically between 30 and 70 cm (12 and 28 in) in length and weigh between 2 and 5 kg (4 and 11 lb). They are superficially similar to marmots, or over-large pikas, but are much more closely related to elephants and sea cows. Hyraxes have a life span from 9 to 14 years. Both types of "rock" hyrax ( P. capensis and H. brucei) live on rock outcrops, including cliffs in Ethiopia[4] and isolated granite outcrops called koppies in southern Africa.[5]

With one exception, all hyraxes are limited to Africa; the exception is the rock hyrax (P. capensis) which is also found in adjacent parts of the Middle East.

Hyraxes were a much more diverse group in the past encompassing species considerably larger than modern hyraxes. The largest known extinct hyrax, Titanohyrax ultimus, has been estimated to weigh 600–1,300 kilograms (1,300–2,900 lb), comparable to a rhinoceros.[6]
