Java mouse-deer

The Java mouse-deer is the smallest hoofed animal in the world. It is only 20–25 cm tall to its shoulders and is about the size of a rabbit. Despite its tiny stature, it is extremely agile and can swiftly disappear into the undergrowth when threatened. Mouse deer are shy animals, hence they are rarely seen in the wild.

Like all chevrotains, Java mousedeer lack antlers or horns. Instead they grow tusk-like canines, protruding teeth that resemble vampire fangs. Rare among herbivores, the fangs are particularly long in males and play an important role in fighting and dominance displays.

Mouse-deer live as solitary animals or in monogamous pairs. Both males and females possess a scent gland under the chin to mark their territory.
