Chevrotains, or mouse-deer, are diminutive, even-toed ungulates that make up the family Tragulidae, and are the only living members of the infraorder Tragulina. The 10 extant species are placed in three genera,[1][2] but several species also are known only from fossils.[3] The extant species are found in forests in South and Southeast Asia; a single species, the water chevrotain, is found in the rainforests of Central and West Africa.[4] In November 2019, conservation scientists announced that they had photographed silver-backed chevrotains (Tragulus versicolor) in a Vietnamese forest for the first time since the last confirmed sightings in 1990.[5][6][7]
They are solitary, or live in loose groupings or pairs, and feed almost exclusively on plant material.[4] Chevrotains are the smallest hoofed mammals in the world. The Asian species weigh between 0.7 and 8.0 kg (1+1⁄2 and 17+3⁄4 lb), while the African chevrotain is considerably larger, at 7–16 kg (15–35 lb).[8] With an average length of 45 cm (18 in) and an average height of 30 cm (12 in), the Java mouse-deer is the smallest surviving ungulate (hoofed) mammal, as well as the smallest artiodactyl (even-toed ungulate).[9] Despite their common name of "mouse deer", they are not closely related to true deer.
