Hyracoidea (Hyrax)

Hyraxes are herbivores that inhabit cliff sides and rocky terrain in arid sub-Saharan Africa and the Middle East. Mature rock hyraxes typically range in weight from 1.8 to 5.4kg and 30–58 cm in length. In managed hyrax, periodontal disease with sequelae such as periapical abscesses and dental fractures are common dental pathologies and are readily identified via diagnostic imaging. The hyrax lung is comprised of left cranial, left middle, left caudal, right cranial, right middle, right caudal, and accessory lobes, with the accessory bronchus originating from the right caudal lobar bronchus, as seen in many mammalian species. Male hyraxes have intraabdominal testes located along the caudal pole of each of their respective kidney. Females have a duplex uterus with hemochorial, villous, and zonary placentation.
