Look Inside the 'Alien Deer': Visual Evidence of How Muntjac Facial Glands Function
By Alexander Ross
Q1: Do all deer species have these large facial glands?
A1: Many cervids possess preorbital glands, including white-tailed deer, mule deer, and elk, but they are dramatically smaller and rarely invert visibly. Muntjacs and closely related species like duikers possess disproportionately massive, highly mobile facial pouches compared to their body size.
Q2: Can muntjac deer spray scent defensively like skunks?
A2: No. Muntjac glands do not possess pressurized reservoirs or projection mechanisms. Scent marking requires physical contact; the animal must rub its face against an object or let atmospheric warmth evaporate the volatile compounds into the immediate air currents.
Q3: Do female muntjacs have preorbital glands, or only males?
A3: Both sexes possess fully functional preorbital glands. While bucks use them heavily for territorial defense and rival appraisal, does utilize them extensively for reproductive signaling and maintaining maternal bonds with their fawns.
Q4: Why do muntjacs also have long canine teeth?
A4: Muntjacs represent an early stage of deer evolution. Before deer evolved massive branched antlers for defense and sexual selection, they relied on sharp downward-pointing tusks. Male muntjacs carry small, simple antlers alongside razor-sharp canines, using both in combat.
