Chinese muntjac (Muntiacus reevesi)—Kenneth W. Fink/Root Resources
Any of about seven species of solitary, nocturnal deer, native to Asia and introduced into England and France, that constitute the genus Muntiacus (family Cervidae). Named for their cry, most species stand 15–25 in. (40–65 cm) high, weigh 33–77 lbs (15–35 kg), and are grayish, reddish, or brown. Males have tusklike upper canine teeth and short one-branched antlers. Bony ridges extend from the antler base onto the face. The giant muntjac (88–110 lbs, or 40–50 kg) was discovered in northern Vietnam in 1993–94. Fea's muntjac (M. feae), of Myanmar and Thailand, is endangered, and other muntjac species are threatened.
