What is the maximal age a Swamp antechinus reaches?
An adult Swamp antechinus (Antechinus minimus) usually gets as old as 2 years.
Swamp antechinuss are around 29 days in the womb of their mother. When born, they weight 5 grams (0.01 lbs) and measure 4.7 cm (0′ 2″). As a member of the Dasyuridae family (genus: Antechinus), a Swamp antechinus caries out around 7 little ones per pregnancy, which happens around 1 times a year. Fully grown, they reach a bodylength of 1.45 meter (4′ 10″).
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 swamp antechinus (Antechinus minimus), also known as the little Tasmanian marsupial mouse, is a species of shrew-like marsupial of the family Dasyuridae and as such is related to dunnarts, quolls and the Tasmanian devil.
