What is the maximal age a Northern short-tailed shrew reaches?
An adult Northern short-tailed shrew (Blarina brevicauda) usually gets as old as 2.75 years.
Northern short-tailed shrews are around 20 days in the womb of their mother. When born, they weight 23.38 kg (51.54 lbs) and measure 6.27 meter (20′ 7″). As a member of the Soricidae family (genus: Blarina), a Northern short-tailed shrew caries out around 5 little ones per pregnancy, which happens around 3 times a year. Fully grown, they reach a bodylength of 12.1 cm (0′ 5″).
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 short-tailed shrew (Blarina brevicauda) is the largest shrew in the genus Blarina, and occurs in the northeastern region of North America. It is a semifossorial, highly active, and voracious insectivore and is present in a variety of habitats like broadleaved and pine forests among shrubs and hedges as well as grassy river banks. It is notable in that it is one of the few venomous mammals. The specific epithet, brevicauda, is a combination of the Latin brevis and cauda, meaning “short tail”.
