Oryx callotis O. Thomas, 1982 (fringe-eared oryx) is a relatively large, long-bodied bovid, with an appropriate common name because of its distinguishing tufts of hair extending from the ends of the ears. It occupies arid lands in Kenya and Tanzania. O. callotis can go up to a month without drinking water if succulent vegetation is available. Some herds have been semidomesticated, and 60% of the presumed 17,000 wild individuals exist in wildlife reserves, currently receiving some protection from settlement and poaching. O. callotis is considered “Vulnerable” by the International Union for Conservation of Nature and Natural Resources but as a subspecies of O. beisa, which is listed as “Near Threatened.”
