''Heterohyrax brucei'', more commonly known as the yellow-spotted rock hyrax or bush hyrax, is a species of mammal in the family Procaviidae. It is found in Angola, Botswana, Burundi, Democratic Republic of the Congo, Southern Egypt, Eritrea, Ethiopia, Kenya, Malawi, Mozambique, Rwanda, Somalia, Northern South Africa, Sudan, Tanzania, Uganda, Zambia, and Zimbabwe. Its natural habitats are dry savanna and rocky areas.〔 Hyrax comes from the Greek word ''hyrak'' which means shrew.〔 ==Naming and classification== ''Heterohyrax'' is a bush hyrax, as opposed to a rock hyrax (''Procavia capensis'')〔 or a tree hyrax (''Dendrohyrax'').〔 The bush hyrax is distinguishable from the rock hyrax as the bush hyrax is less heavily built and has a narrower muzzle than the rock hyrax. Hyraxes have molariform teeth that are brachydont, meaning they have short crowns and well-developed roots. The hyraxes vary in that the bush hyrax has an upper premolar series that is the same length as the molar series, while the rock hyrax has a shorter upper premolar series and the tree hyrax has a longer upper premolar series. Hyraxes also have upper incisors that appear tusk-like〔Barry, R.E., & Shoshani, J. (2000). Mammal Species: ''Heterohyrax brucei''. ''American Society of Mammalogists.'' 645:1-7.〕 and four lower incisors that are comb-like and used to groom the fur.〔 While the incisors do not differentiate between the hyraxes, they do differ between sexes. Males have rigid upper incisors while the females have rounded upper incisors. Furthermore, the male sex organs also differ greatly between these three genera of hyraxes which inhibit them from interbreeding.〔 Common names for the bush hyrax include yellow-spotted hyrax, bush hyrax, hogger hyrax, yellow-spotted rock hyrax, and ''daman de steppe'' (French).〔 The genus ''Heterohyrax'' contains one extinct species, ''H. auricampensis'', and one living, ''H. brucei''. Within ''H. brucei'' there are 25 recognized subspecies.〔 ''Heterohyrax'' belongs to the superordinal clade of endemic African mammals that includes elephant shrews, aardvarks, golden moles, elephants and sirenians.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Yellow-spotted rock hyrax」の詳細全文を読む スポンサード リンク
