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 discriminatory when trying to differentiate a muntjac from an immature native deer, although water deer also have visible tusks; however, they are much less widespread. Muntjac are of great interest in evolutionary studies because of their dramatic chromosome variations and the recent
Indian muntjac usually branch just once near the base, and a large postorbital scent gland used to mark territories. The species was formerly classified as "". The Indian muntjac has a short but very soft, thick, dense coat that is more dense in cooler regions. The face of the muntjac is darker and the limbs are dark to reddish brown and the coat color seasonally varies from darker brown to yellowish and grayish brown and is white ventally.
