Oryx callotis (Artiodactyla: Bovidae)

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.”

Elaphodus cephalophus (Artiodactyla: Cervidae)

Elaphodus cephalophus Milne-Edwards, 1872 (tufted deer) is usually considered polytypic with 3 or 4 recognized subspecies, depending on the source. It is a small dark chocolate-brown deer typified by a tuft of hair on its crown, sharp upper canines that protrude downward from under the upper lip, and rudimentary antlers on males; it is similar to muntjacs, to which it is closely related. E. cephalophus occurs in humid, montane forests at elevations of 300–4,750 m in southwestern through southeastern China and perhaps northwestern Myanmar (historical records). Vulnerable to poaching in remote areas and relatively uncommon in zoos, it is considered vulnerable as a Class II species in China and listed as “Near Threatened” by the International Union for Conservation of Nature and Natural Resources.
