What is the maximal age a Rufous rat-kangaroo reaches?
An adult Rufous rat-kangaroo (Aepyprymnus rufescens) usually gets as old as 8 years.
Rufous rat-kangaroos are around 22 days in the womb of their mother. When born, they weight 5.24 kg (11.55 lbs) and measure 4.3 cm (0′ 2″). As a member of the Potoroidae family (genus: Aepyprymnus), a Rufous rat-kangaroo caries out around 1 little ones per pregnancy, which happens around 3 times a year. Fully grown, they reach a bodylength of 1.42 meter (4′ 8″).
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 rufous rat-kangaroo (Aepyprymnus rufescens), more commonly known as the rufous bettong, is a small marsupial species of the family Potoroidae found in Australia. It is not classified as threatened. The rufous bettong is about the size of a full-grown rabbit.
