The Siberian musk deer (Moschus moschiferus) is a small, nocturnal ungulate native to forested and mountainous regions of Northeast Asia. Distinguished by its elongated fangs and absence of antlers, it is known for the musk gland in males, used in perfumery. This solitary creature plays a vital role in its ecosystem as both prey and seed disperser.

Moschus moschiferus, commonly known as the Siberian musk deer, is native to Asia. Its geographical distribution includes parts of Russia (specifically Siberia), Mongolia, Kazakhstan, North Korea, and parts of China, including the northeastern provinces and the Tibetan Plateau.

The Siberian musk deer typically inhabits mountainous regions with dense coniferous or mixed forests. It prefers areas with rugged terrain, steep slopes, and abundant undergrowth, which provide cover from predators. The climate in these regions is usually cold, with long, harsh winters and short, cool summers.

Moschus moschiferus is adapted to a solitary and crepuscular lifestyle, often active during twilight hours. It feeds primarily on leaves, twigs, and grasses, utilizing its specialized digestive system to extract nutrients from fibrous plant material. The musk deer plays a role in its ecosystem as both a herbivore and prey species, contributing to the forest's biodiversity and serving as a food source for predators like lynxes and snow leopards.
