Musk deer can refer to any one, or all seven, of the species that make up Moschus, the only extant genus of the family Moschidae. The musk deer family differs from cervids, or true deer, by lacking antlers and facial glands and by possessing only a single pair of teats, a gallbladder, a caudal gland, a pair of tusk-like teeth and—of particular economic importance to humans—a musk gland.
Musk deer live mainly in forested and alpine scrub habitats in the mountains of southern Asia, notably the Himalayas. Moschids, the proper term when referring to this type of deer rather than one/multiple species of musk deer, are entirely Asian in their present distribution, being extinct in Europe where the earliest musk deer are known to have existed from Oligocene deposits.
Musk deer resemble small deer with a stocky build, and hind legs longer than their front legs. They are about 80 to 100 cm (31 to 39 in) long, 50 to 70 cm (20 to 28 in) high at the shoulder, and weigh between 7 and 17 kg (15 and 37 lb). The feet of musk deer are adapted for climbing in rough terrain. Like the Chinese water deer, a cervid, they have no antlers, but the males do have enlarged upper canines, forming sabre-like tusks. The dental formula is similar to that of true deer: 0.1.3.33.1.3.3
The musk gland is found only in adult males. It lies in a sac located between the genitals and the umbilicus, and its secretions are most likely used to attract mates.
