The tufted deer (Elaphodus cephalophus) is a small species of deer characterized by a prominent tuft of black hair on its forehead and fang-like canines for the males. It is a close relative of the muntjac, living somewhat further north over a wide area of central China northeastern Myanmar. Suffering from overhunting and habitat loss, this deer is considered near-threatened. It is the only member of the genus Elaphodus. It is restricted to forested mountain habitat up to 4500 m above sea level, making study difficult. Order: Artiodactyla, Family: Cervidae, Subfamily: Cervinae, Genus: Elaphodus, Species: Elaphodus cephalophus Milne-Edwards, 1872.
