The four species of musk deer make up the family Moschidae. They are more primitive than the true deer (family Cervidae) in not having antlers or facial glands, in having only a single pair of teats, and in possessing a gall bladder, a caudal gland, and—of particular economic importance to humans—a musk gland.
