What is the maximal age a European water vole reaches?

An adult European water vole (Arvicola terrestris) usually gets as old as 5 years.

European water voles are around 21 days in the womb of their mother. When born, they weight 5 grams (0.01 lbs) and measure 4 cm (0′ 2″). As a member of the Muridae family (genus: Arvicola), a European water vole caries out around 4 little ones per pregnancy, which happens around 3 times a year.
