What is the maximal age a Brown antechinus reaches?
An adult Brown antechinus (Antechinus stuartii) usually gets as old as 3 years.
Brown antechinuss are around 28 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 Brown antechinus caries out around 6 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 brown antechinus (Antechinus stuartii), also known as Stuart’s antechinus and Macleay’s marsupial mouse, is a species of small carnivorous marsupial of the family Dasyuridae. The males die after their first breeding season, and the species holds the world record for being the world’s smallest semelparous mammal.
