Tusks buck with exposed canine tooth , slanted pedicles and branched antlers. A distinct coronet, or burr, is visible at the antler-pedicle junction. Males have short antlers, which can regrow, but they tend to fight for territory with their "tusks" (downward-pointing canine teeth). The presence of these "tusks" is otherwise unknown in native British wild deer and can be an identifying feature to differentiate a muntjac from an immature native deer.
Water deer also have visible tusks but they are much less widespread. Although these tusks resemble those of both water deer and the
musk deer, the muntjac is not related to either of these (and they are not related to each other). The tusks are of a quite different shape in each.
Glands , India s have been shed for summer. Muntjacs possess various scent glands that have crucial functions in communication and territorial marking. They use their facial glands primarily to mark the ground and occasionally other individuals, and the glands are opened during defecation and urination, as well as sometimes during social displays. While the frontal glands are typically opened involuntarily as a result of facial muscle contractions, the
preorbital glands near the eyes can be voluntarily opened much wider and even everted to push out the underlying glandular tissue. Even young fawns are capable of fully everting their preorbital glands. ==Genetics==
