It is hard to guess what a Western grey kangaroo weights. But we have the answer:
An adult Western grey kangaroo (Macropus fuliginosus) on average weights 25.58 kg (56.4 lbs).
The Western grey kangaroo is from the family Macropodidae (genus: Macropus). They can live for up to 20 years. When reaching adult age, they grow up to 64.6 cm (2′ 2″). On average, Western grey kangaroos can have babies 1 times per year with a litter size of 1.
As a reference: An average human weights in at 62 kg (137 lbs) and reaches an average size of 1.65m (5′ 5″). Humans spend 280 days (40 weeks) in the womb of their mother and reach around 75 years of age.
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.
