What is the maximal age a Arctic shrew reaches?
An adult Arctic shrew (Sorex arcticus) usually gets as old as 1.5 years.
Arctic shrews are around 17 days in the womb of their mother. When born, they weight 90 grams (0.2 lbs) and measure 1.09 meter (3′ 7″). As a member of the Soricidae family (genus: Sorex), a Arctic shrew caries out around 6 little ones per pregnancy, which happens around 1 times a year. Fully grown, they reach a bodylength of 7.5 cm (0′ 3″).
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 Arctic shrew (Sorex arcticus), also known as the blackback shrew or saddlebacked shrew, is a medium-sized shrew found in Canada and the northern United States. Separate species status has been proposed for the maritime shrew (Sorex maritimensis) which is found in New Brunswick and Nova Scotia and had been considered to be a subspecies of the Arctic shrew. The tundra shrew (Sorex tundrensis) was formerly considered to be a subspecies of the Arctic shrew.
