It is hard to guess what a Australian swamp rat weights. But we have the answer:
An adult Australian swamp rat (Rattus lutreolus) on average weights 106 grams (0.23 lbs).
The Australian swamp rat is from the family Muridae (genus: Rattus). It is usually born with about 4 grams (0.01 lbs). They can live for up to 2.42 years. When reaching adult age, they grow up to 16 cm (0′ 7″). On average, Australian swamp rats can have babies 2 times per year with a litter size of 4.
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 Australian swamp rat (Rattus lutreolus), also known as the eastern swamp rat, is a species of rat native to the coasts of southern and eastern Australia.
