What is the maximal age a Alpine pika reaches?
An adult Alpine pika (Ochotona alpina) usually gets as old as 3 years.
Alpine pikas are around 28 days in the womb of their mother. When born, they weight 8 grams (0.02 lbs) and measure 5.1 cm (0′ 3″). As a member of the Ochotonidae family (genus: Ochotona), a Alpine pika caries out around 3 little ones per pregnancy, which happens around 2 times a year. Fully grown, they reach a bodylength of 17.5 cm (0′ 7″).
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 alpine pika (Ochotona alpina) is a species of small mammal in the pika family, Ochotonidae. The summer pelage of different subspecies varies drastically but, in general, it is dark or cinnamon brown, turning to grey with a yellowish tinge during the winter. The alpine pika is found in western Mongolia, eastern Kazakhstan, and Russia (Tuva, Irkutsk, Altai, and Krasnoyarsk), as well as in China (northern Xinjiang and Heilongjiang), in very cold, mountainous regions. It is a generalist herbivore, and mainly forages on mosses, tree branches, pine nuts, and plant stems. It can emit three series of different vocalizations: a long call, a short call, and an alarm call. It is rated as a species of least concern on the IUCN Red List of Endangered Species.
