What is the maximal age a Common wallaroo reaches?
An adult Common wallaroo (Macropus robustus) usually gets as old as 24 years.
Common wallaroos are around 34 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 common wallaroo (Osphranter robustus) or wallaroo, also known as euro or hill wallaroo is a species of macropod. The word euro is particularly applied to one subspecies (O. r. erubescens).The eastern wallaroo is mostly nocturnal and solitary, and is one of the more common macropods. It makes a loud hissing noise and some subspecies are sexually dimorphic, like most wallaroos.
