How old does a Water vole (North America) get? (age expectancy)

What is the maximal age a Water vole (North America) reaches?

An adult Water vole (North America) (Microtus richardsoni) usually gets as old as 0.75 years.

Water vole (North America)s are around 22 days in the womb of their mother. When born, they weight 5 grams (0.01 lbs) and measure 4.3 cm (0′ 2″). As a member of the Muridae family (genus: Microtus), a Water vole (North America) caries out around 5 little ones per pregnancy, which happens around 2 times a year. Fully grown, they reach a bodylength of 15.4 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.

A Water vole (North America) gets as old as 0.75 years

The water vole (Microtus richardsoni) is the largest North American vole. It is found in the northwestern United States and southern parts of western Canada. This animal has been historically considered a member of genus Arvicola, but molecular evidence demonstrates that it is more closely related to North American Microtus species. Water voles are on the USDA Forest Service Region 2 sensitive species list because they maintain very small populations and there is high concern that their required habitat may be declining.These animals have gray-brown or red-brown fur with gray under parts. Their large hind feet help make them excellent swimmers, and they are found in alpine or semi-alpine meadows near water. They feed on grasses, leaves, roots and seeds, also eating small invertebrates. Water voles dig burrows that are connected to water sources, and are considered a semi-aquatic species.They are active year-round, tunneling through snow during the winter. Their burrows often have entrances at the water’s edge or under water, and they usually live in colonies of 8-40 individuals along the waterway.
