What is the maximal age a Red-necked wallaby reaches?
An adult Red-necked wallaby (Macropus rufogriseus) usually gets as old as 19 years.
Red-necked wallabys are around 30 days in the womb of their mother. When born, they weight 449 grams (0.99 lbs) and measure 1.2 meter (4′ 0″). As a member of the Macropodidae family (genus: Macropus), a Red-necked wallaby caries out around 1 little ones per pregnancy, which happens around 1 times a year. Fully grown, they reach a bodylength of 87.7 cm (2′ 11″).
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 red-necked wallaby or Bennett’s wallaby (Macropus rufogriseus) is a medium-sized macropod marsupial (wallaby), common in the more temperate and fertile parts of eastern Australia, including Tasmania. Red-necked wallabies have been introduced to several other countries, including New Zealand, England, Scotland, Ireland, France and the Isle of Man.
