Kingdom: Animalia
Phylum: Chordata
Subphylum: Vertebrata
Class: Mammalia
Order: Artiodactyla
Family: Moschidae
Genus: Moschus
Species: Moschus chrysogaster

Geographic Range

Moschus chrysogaster lives along the Himalayas in Nepal, northern India, southern China, Afghanistan, Bhutan, and Pakistan (CITES,2001; Shrestha,1989; Sathyakumar,1993; Kattel,1991).

Habitat

Elevation
2400 to 4500 m
(7872 to 14760 ft)


M. chrysogaster usually lives in forests with moderate to steep slopes (Kattel,1991). M. chrysogaster is found in oak or fir forests (Kattel,1991) and can be found up to the tree line (usually about 4500 m) in mountains. Plants that may be found in its habitat include birch, rhododendron, blue pine, fir, oak, juniper, grass, lichens and shrubs (Kattel,1991; Green,1987).

These animals are found in the following types of habitat:
temperate ; terrestrial .

Terrestrial Biomes:
forest ; scrub forest ; mountains .

Physical Description

Mass
10 to 15 kg; avg. 12.50 kg
(22 to 33 lbs; avg. 27.5 lbs)


Length
100 cm (average)
(39.37 in)


M. chrysogaster looks like a small deer with long upper canines that are visible even when the mouth is closed. It's tail is hairless except for a small tuff at the end (Shrestha, 1989), and it has long "hare-like" ears (Sathyakumar,1993). It has an externally visible musk sac that lies between its reproductive organs and umbilicus (Shrestha, 1989). The opening to the sac lies anterior to the urethra (Shrestha, 1989). A musk deer is about 60cm tall and has a shoulder height of about 20cm (Shrestha, 1989).

Musk deer have a caudal gland at the base of their tails (Green,1985-1987).

Some key physical features:
endothermic ; bilateral symmetry .

Reproduction

Birth Mass
800 g (average)
(28.16 oz)
[External Source: AnAge]


Age at sexual or reproductive maturity (female)
639 days (average)
[External Source: AnAge]


The mating season is December to January (Shrestha,1989).

Key reproductive features:
gonochoric/gonochoristic/dioecious (sexes separate); sexual .

Lifespan/Longevity

Extreme lifespan (captivity)
17 years (high)

Average lifespan (wild)
3.10 years

Average lifespan (captivity)
2.40 years

The average lifespan of captive bred M. chrysogaster is 2.4 years. The average lifespan of wild caught captive M. chrysogaster is about 7 years. The oldest captive Dwarf musk deer (M. berezovskii) from China had a lifespan of 20 years (Sathyakumar,1993).

Behavior

M. chrysogaster is a solitary animal with a "bounding gait" (Sathyakumar,1993). The adult males are probably territorial. One interesting aspect of the species is that they usually defecate (but never urinate) at a latrine, which is a spot designated by M chrysogaster as a "toilet". They always squat when urinating or defecating.

They scent mark by rubbing the caudal gland located at the base of their tail against plants. This leaves a greasy smear on the plant (Green,1985-1987).

Key behaviors:
nocturnal ; crepuscular ; motile ; solitary .

Food Habits

M. chrysogaster is a ruminant (Sathyakumar,1993). It can live on poor quality food. In autumn and winter, it mostly eats forbs and the woody plant leaves of trees and shrubs such as oak and gaultheria. In spring and summer, its diet consists mainly of forbs and lichens (Green,1987).

Primary Diet:
herbivore (folivore ).

Plant Foods:
leaves; lichens.

Predation

Known predators

M. chrysogaster has a shy nature (Sathyakumar,1993), and is easily alarmed (Kattel,1991). It is a solitary animal (Sathyakumar,1993) that is wary of humans.

Economic Importance for Humans: Positive

The musk is used by humans to make soap, perfume (Myers,1999) and indigenous medicine (Sathyakumar,1993).

Ways that people benefit from these animals:
source of medicine or drug .

Conservation Status

IUCN Red List: [link]:
Lower Risk - Near Threatened.

US Federal List: [link]:
Endangered.

CITES: [link]:
Appendix I.

CITES Appendix I Afghanistan, India, Nepal, Pakistan

Appendix II Bhutan, China

The M. chrysogaster population around the Himalayan area has decreased greatly because of poaching animals for their musk and the destruction of natural habitats both by livestock and by local people who collect bamboo for domestic use (Sathyakumar,1993).

One method of conserving M. chrysogaster is by extracting the musk without killing the musk deer. However, this method takes more time, and is more traumatizing for the musk deer (Shrestha,1989). Musk deer farms are used for this purpose, but these farms have high mortality rates. The main causes of deaths in these farms are trauma, pneumonia and diarrhea (Sathyakumar,1993).

Some problems that may contribute to the high mortality rate are low quality buildings, poor equipment, lack of adequate money, lack of skilled workers, and the remoteness and cold climate of the farm location (Sathyakumar,1993).

In China, there has been reports of success in cutting down mortality rate in Dwarf musk deer farms. In Fozling Farm, Anhui, the survival of young increased from 50% to >90%. In Ma Er Kang Farm, Sichuan, the young survival rate was 74% from 1959 to 1973 for three hundred and thirty-six Dwarf musk deer (Sathyakumar, 1993).

The reasons for keeping musk deer farms are for musk production, research, reintroduction into wild, and reintroduction to existing wild populations (Sathyakumar,1993).

Other Comments

The caudal gland located at the base of the tail secretes a foul smelling viscous yellow substance (Green,1985-1987).

The musk pod is located only in males, and secretes musk (Sathyakumar, 1993). The musk is of highest quality during mating season which is from December to January. During this time, it is a dark red brown granular powder with a strong smell. During November, April, and June, the musk quality is poorer. It has a pasty appearance, its color is creamy white, and it has little smell (Shrestha,1989). The external musk pod is roughly 4.1cm long, 3.3cm wide, and 4.6cm deep (Shrestha,1989).
