What is the maximal age a Red kangaroo reaches?
An adult Red kangaroo (Macropus rufus) usually gets as old as 30 years.
Red kangaroos are around 33 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), their offspring is 1 babies per pregnancy. 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 kangaroo (Osphranter rufus) or red giant kangaroo is the largest of all kangaroos, the largest terrestrial mammal native to Australia, and the largest extant marsupial. It is found across mainland Australia, except for the more fertile areas, such as southern Western Australia, the east and southeast coasts, and the rainforests along the northern coast.
