What is the maximal age a Australian swamp rat reaches?
An adult Australian swamp rat (Rattus lutreolus) usually gets as old as 2.42 years.
Australian swamp rats are around 24 days in the womb of their mother. When born, they weight 4 grams (0.01 lbs) and measure 4.4 cm (0′ 2″). As a member of the Muridae family (genus: Rattus), a Australian swamp rat caries out around 4 little ones per pregnancy, which happens around 2 times a year. Fully grown, they reach a bodylength of 16 cm (0′ 7″).
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.
