Animal Age

How old does a Japanese serow get? (age expectancy)

What is the maximal age a Japanese serow reaches?

An adult Japanese serow (Naemorhedus crispus) usually gets as old as 18.5 years.

Japanese serows are around 212 days in the womb of their mother. When born, they weight 3.5 kg (7.72 lbs) and measure 5.3 cm (0′ 3″). As a member of the Bovidae family (genus: Naemorhedus), a Japanese serow caries out around 1 little ones per pregnancy, which happens around 1 times a year. Fully grown, they reach a bodylength of 1.04 meter (3′ 5″).

As a reference: Usually, humans get as old as 100 years, with the average being around 75 years. After being carried in the belly of their mother for 280 days (40 weeks), they grow to an average size of 1.65m (5′ 5″) and weight in at 62 kg (137 lbs), which is obviously highly individual.

The Japanese serow (氈鹿, lit. “coarse pelt deer”): (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 81 centimetres (32 in) tall and weigh 30–45 kilograms (66–99 lb). 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 the 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.
