It is hard to guess what a Glacier rat weights. But we have the answer:
An adult Glacier rat (Stenomys richardsoni) on average weights 66 grams (0.15 lbs).
The Glacier rat is from the family Muridae (genus: Stenomys). When reaching adult age, they grow up to 12.8 cm (0′ 6″). Usually, Glacier rats have 2 babies per litter.
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 glacier rat (Rattus richardsoni) is a species of rodent in the family Muridae. It is endemic to the New Guinea Highlands near Puncak Trikora (=Mt. Wilhelmina) and Puncak Jaya (=Carstensz Pyramid), West Papua, Indonesia. Its altitudinal range is 3,225–4,500 m (10,581–14,764 ft) above sea level.
