How old does a House mouse get? (age expectancy)

What is the maximal age a House mouse reaches?

An adult House mouse (Mus musculus) usually gets as old as 6 years.

House mouses are around 19 days in the womb of their mother. When born, they weight 1 grams (0 lbs) and measure 2.1 cm (0′ 1″). As a member of the Muridae family (genus: Mus), a House mouse caries out around 5 little ones per pregnancy, which happens around 4 times a year. Fully grown, they reach a bodylength of 99.5 cm (3′ 4″).

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.

A House mouse gets as old as 6 years

The house mouse (Mus musculus) is a small mammal of the order Rodentia, characteristically having a pointed snout, large rounded ears, and a long and hairy tail. It is one of the most abundant species of the genus Mus. Although a wild animal, the house mouse has benefited significantly from associating with human habitation to the point that truly wild populations are significantly less common than the semi-tame populations near human activity.The house mouse has been domesticated as the pet or fancy mouse, and as the laboratory mouse, which is one of the most important model organisms in biology and medicine. The complete mouse reference genome was sequenced in 2002.
