The Japanese serow (''Capricornis crispus'') is a Japanese goat-antelope, an even-toed ungulate mammal. It is found in dense woodland in Japan, primarily in northern and central Honshu. The animal is seen as a national symbol of Japan and is subject to protection in conservation areas. Adult Japanese serow stand about tall and weigh . They are black to whitish, and colouring lightens in summer. The fur is very bushy, especially the tail. Both sexes have short, backwards-curving horns and are difficult to distinguish by sight. Japanese serow are found in dense mountain forests where they eat leaves, shoots, and acorns. They are diurnal and feed in early mornings and late afternoons. Serows are solitary, or gather in couples or small family groups. The animal marks its territory with sweet-and-sour-smelling preorbital gland secretions, and males and females have separate territories that may overlap. In the mid-20th century the Japanese serow was hunted to near-extinction. In 1955 the Japanese government passed a law designating it a "Special National Monument" to protect it from poachers. Populations have since grown so greatly that IUCN Red List of Threatened Animals ranks it "least concern". Complaints from foresters and farmers led in 1979 to the 1955 law's repeal. Since then the serow has had protected status in 13 designated protected areas over 23 prefectures, and has been subject to culling as a pest outside conservation areas. Conservationists have labelled it a "living national treasure of the forest". Athletes with superior agility and speed draw comparisons with the serow, and the Yamaha Motor Company has marketed the XT 225 enduro motorcycle as the Yamaha Serow. ==Taxonomy== Coenraad Jacob Temminck first described the Japanese serow in 1836, and named it ''Antilope crispa''. John Edward Gray gave it its current name in 1846. Pierre Marie Heude proposed many new genera and species in a system published in 1898; ''Capricornis'' became ''Capricornulus'', which included ''crispus'', ''pryerianus'', and ''saxicola''. The system did not find acceptance. There is no fossil record of the Japanese serow; its evolutionary history and the closeness of its relation to the Taiwan serow (''Capricornis swinhoei'') are speculative Its taxonomic position has led to its being called a "living fossil". Karyotype studies indicate it was the earliest species to split from the common ''Capricornis'' ancestor. The closest relative to the Japanese Serow is the Taiwan serow (''Capricornis swinhoei''). Genetically, there is little difference between Japanese and Taiwan serows; their karyotype is essentially the same: 2n=50, FN=60. The Taiwan serow is smaller and shorter-haired, with browner fur and a white patch under the chin and throat. Phylogenetically ''Capricornis'' is closer to goats and sheep than cattle. The nomenclature and status of ''Capricornis'' taxa are not completely resolved. Some researchers have considered ''Capricornis'' a junior synonym of ''Naemorhedus'', a classification that includes gorals; molecular analysis has not supported this classification. ''Capricornis'' has a lower canine, which ''Naemorhedus'' species usually do not. In Japan, the serow is widely thought of as a kind of deer, though deer and serows are not even of the same infraclass. In the past, the Japanese word ' was written using the Chinese character for ', meaning "deer". Today, when written using Chinese characters, the characters for "antelope" and "sheep" are used. Sometimes the serow is mistaken for a wild boar. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Japanese serow」の詳細全文を読む スポンサード リンク
