What is the maximal age a Northern bat reaches?
An adult Northern bat (Eptesicus nilssoni) usually gets as old as 15.5 years.
When born, they weight 3 grams (0.01 lbs) and measure 8 cm (0′ 4″). As a member of the Vespertilionidae family (genus: Eptesicus), a Northern bat caries out around 1 little ones per pregnancy, which happens around 1 times a year. Fully grown, they reach a bodylength of 13.8 cm (0′ 6″).
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 northern bat (Eptesicus nilssonii) is the most abundant species of bat in northern Eurasia. It is found from England to HokkaidÅ and down to northern India. It is closely related to the serotine bat (Eptesicus serotinus).
