It is hard to guess what a Mountain viscacha rat weights. But we have the answer:
An adult Mountain viscacha rat (Octomys mimax) on average weights 124 grams (0.27 lbs).
The Mountain viscacha rat is from the family Octodontidae (genus: Octomys). When reaching adult age, they grow up to 28 cm (1′ 0″).
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 mountain viscacha rat or mountain vizcacha rat (Octomys mimax), historically viscacha rat or vizcacha rat, is a species of rodent in the family Octodontidae. It is endemic to Argentina.It is the only living species within the genus Octomys. This diploid genus (2n = 56) may be ancestral to the two unusual suspected tetraploid species Tympanoctomys barrerae and Pipanacoctomys aureus. However, some genetic studies have rejected any polyploidism in mammals as unlikely, and suggests that amplification and dispersion of repetitive sequences best explain the large genome size.
