What is the maximal age a Dusky antechinus reaches?
An adult Dusky antechinus (Antechinus swainsonii) usually gets as old as 2 years.
Dusky 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 Dusky antechinus caries out around 8 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 dusky antechinus (Antechinus swainsonii), also known as Swainson’s antechinus or the dusky marsupial mouse, is a species of small marsupial carnivore, a member of the family Dasyuridae. It is found in Australia.
