What is the maximal age a Western grey kangaroo reaches?
An adult Western grey kangaroo (Macropus fuliginosus) usually gets as old as 20 years.
Western grey kangaroos 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 Western grey kangaroo caries out around 1 little ones per pregnancy, which happens around 1 times a year. Fully grown, they reach a bodylength of 64.6 cm (2′ 2″).
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 western grey kangaroo (Macropus fuliginosus), also referred to as a western grey giant kangaroo, black-faced kangaroo, mallee kangaroo, and sooty kangaroo, is a large and very common kangaroo found across almost the entire southern part of Australia, from just south of Shark Bay through coastal Western Australia and South Australia, into western Victoria, and in the entire Murray–Darling basin in New South Wales and Queensland.
