It is hard to guess what a Irenomys weights. But we have the answer:
An adult Irenomys (Irenomys tarsalis) on average weights 43 grams (0.09 lbs).
The Irenomys is from the family Muridae (genus: Irenomys). When reaching adult age, they grow up to 11.5 cm (0′ 5″). Usually, Irenomyss have 3 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.
Irenomys tarsalis, also known as the Chilean climbing mouse, Chilean tree mouse, or long-footed irenomys, is a rodent found in Chile, from about 36° to 46°S, and in adjacent Argentina, mainly in forests. It is a large, long-tailed, soft-furred mouse characterized by grooved upper incisors and specialized molars with transverse ridges, divided by deep valleys, which are connected by a transverse ridge along the midline of the molars.I. tarsalis is a docile, herbivorous animal that lives in trees. It is so distinct from other species that it was placed in its own genus, Irenomys, in 1919. The name comes from the Ancient Greek word εἰρήνη (iren) meaning “peace”, in reference to the end of World War I. Although it has been generally placed in the tribe Phyllotini, genetic evidence does not support any close relationships with other genera, so that it is now classified as a member of the subfamily Sigmodontinae incertae sedis (of uncertain position).
