The Siberian musk deer (Moschus moschiferus) is a musk deer found in the mountain forests of Northeast Asia. It is most common in the taiga of southern Siberia, but is also found in parts of Mongolia, Inner Mongolia, Manchuria and the Korean peninsula.

Characteristics[edit]

Skull

It is largely nocturnal, and migrates only over short distances. It prefers altitudes of more than 2600 m. Adults are small, weighing 7–17 kg.

The Siberian musk deer is classified as threatened by the IUCN. It is hunted for its musk gland, which fetches prices as high as $45,000 per kilogram. Only a few tens of grams can be extracted from an adult male. It is possible to remove the gland without killing the deer, but this is seldom done.

The most striking characteristics of the Siberian musk deer are its tusks and kangaroo-like face. Males grow the teeth for display instead of antlers.[2]

A distinct subspecies roams the island of Sakhalin.

Musk chemical composition[edit]

Siberian musk deer preputial gland secretions are constituted of free fatty acids and phenols (10%), waxes (38%) and steroids. Cholestanol, cholesterol, androsterone, Δ4-3α-hydroxy-17-ketoandrostene, 5β,3α-hydroxy-17-ketoandrostane, 5α,3β,17α-dihydroxyandrostane, 5β,3α,17β-dihydroxyandrostane and 5β,3α,17α-dihydroxyandrostane can be isolated from the steroid fraction. 3-Methylpentadecanone (muscone) was not identified among the secretion lipids.[4]
