It is hard to guess what a Arianus’s rat weights. But we have the answer:
An adult Arianus’s rat (Rattus omichlodes) on average weights 70 grams (0.15 lbs).
The Arianus’s rat is from the family Muridae (genus: Rattus). When reaching adult age, they grow up to 13.2 cm (0′ 6″).
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.
Arianus’s rat (Rattus omichlodes), also known as Arianus’ New Guinea mountain rat, is a species of rat native to the mountains of Papua Province, Indonesia.
