Moschus fuschus is found in the southeastern Xizang and western Yunnan portions of China. This species is also found in northern Burma and southeastern Tibet. (Hoptner, et al., 1988; Nowak, 1999; Wilson and Reeder, 1993; Yang, et al., 2002)
Moschus does not have the facial glands of most Cervids, and unlike most Cervids, also posesses a gall bladder. Mature males have a musk gland, located ventrally between navel and genetalia, which is absent in females and juveniles. Females have two mammae. (Hoptner, et al., 1988; Nowak, 1999; Yang, et al., 2002)resembles a small deer, with weights varying between 10 and 15 kg, and lengths varying between 70 and 100 cm. Hind legs are notably longer and more robust than front legs, allowing for saltatorial motion. Males and females are similar in size, and neither have antlers. Both sexes have thick, coarse hair which provides protection from harsh alpine climates. Pelage is generally brown, although there is a good deal of variation in base color, as well in vibrancy of markings such as spotting. Hair is generally paler ventrally and on inner surfaces of legs. There is a yearly molt. Males show elongate unrooted upper canines, which form curved sabers that can extend well below the lower jaw at maturity. The upper canines of females are always present but do not extend out of the mouth. The dental formula is (i0/1 c1/1 p3/3 m3/3)=34. Eyes and ears are large and well developed.
While there is little known about Moschus moschiferus, males scent mark and defend a territory during breeding season. The scent gland present on male implies that they probably engage in similar behavior. (Hoptner, et al., 1988; Nowak, 1999; Wilson and Reeder, 1993)in particular, other musk deer have been known to come into estrus from the end of November and into December, over a period of about three to four weeks. Males mate with multiple females. In
Gestation lasts from 185 to 195 days. Parturition is in June and July, and females usually have one to two young. Although data from Moschus young are spotted at birth, and typically weigh around 500 g. Weaning occurs between 3 and 4 months of age, and full size is reached around the age of 6 months. Because of this, we can assume that it is possible for females to produce young annually. Both males and females apparently reach sexual maturity around 18 months of age. (Hoptner, et al., 1988; Nowak, 1999; Wilson and Reeder, 1993)are not available, it is reasonable to assume that development of the young is similar to that seen in other members of the genus.
Parental care in this species has not been described extensively. Artiodactyls are generally precocial. Females nurse their young for approximately 3 to 4 months. During this time, it is likely that the young travel with the female as she forages. Females probably provide defense for their young as well as grooming. It is not known whether young continue to associate with their mother past weaning. The role of males in parental care is unknown. (Nowak, 1999)
Moschus species are typically solitary. It is rare to see more than two together, except in cases of a female with young, and males especially are territorial. These animals are mostly active at dawn, dusk, and at night. Communication is generally through scent markings from caudal, interdigital, and musk glands, as well as through urination and defication. Some species have been known to urinate and deficate in common latrines during the autumn and winter months. (Hoptner, et al., 1988; Nowak, 1999; Wilson and Reeder, 1993; Yang, et al., 2002)
It is reported that Moschus communicates through scent from interdigital, caudal, and musk glands, as well as through urination and defecation. Musk deer also make a low, hissing noise, and fight when put together in ill fated attempts to raise them commercially. Their large ears and eyes suggest keen hearing and eyesight, and reliance on these senses. Although not specifically reported, we can infer that tactile communication is important, especially between mothers and their offspring and mates. (Hoptner, et al., 1988; Nowak, 1999; Shusheng and Shila, 2000; Wilson and Reeder, 1993; Yang, et al., 2002)
The principle predator of musk deer is Homo sapiens, which hunts these animals for their musk glands. Lynx, wolverine , and yellow-throated marten have been known to prey on young musk deer. One study found musk deer remains in 43% of lynx feces. Musk deer may evade their predators by remaining cryptic and using the dense vegetation they inhabit to hide. (Hoptner, et al., 1988; Shusheng and Shila, 2000; Yang, et al., 2002)
The role of these animals within their ecosystem has not been reported. We may reasonably infer that they have some impact on vegetation through their foraging behavior. They are also important in food webs, as evidenced by the high number of lynx scats found with musk deer remains.
The musk glands of mature male Moschus have been of historic and current importance for use in soaps and perfumes. Males are hunted and trapped for musk, which, on the 1986 international market, was worth more than gold at U.S. $45,000 per kilogram. Musk has also been used as a component of traditional medicine in China, as a stimulant and as a sedative. (Nowak, 1999; Yang, et al., 2002)
It is unlikely that these shy deer have any negative impact on humans.
It is assumed thatis very rare, although the population size is unknown, as the distribution is limited. The species is listed in CITES Appendix 1.
All musk deer have been hunted extensively for the musk glands of the mature males. During the 1960s when musk prices were high, the annual kill rate in China was about 500,000 animals. This overexploitation led to an extreme populaion crash, with the estimated number of musk deer in China falling to one million from about three million (in the 1950s). The population of Siberian musk deer was estimated to fall 70% in roughly a decade (from the 1980s to 1990s) due to overhunting.
