How many baby Irenomyss are in a litter?
A Irenomys (Irenomys tarsalis) usually gives birth to around 3 babies.
Upon birth, they weight 6.8 kg (14.99 lbs) and measure 15.1 cm (0′ 6″). They are a member of the Muridae family (genus: Irenomys). An adult Irenomys grows up to a size of 11.5 cm (0′ 5″).
To have a reference: Humans obviously usually have a litter size of one ;). Their babies are in the womb of their mother for 280 days (40 weeks) and reach an average size of 1.65m (5′ 5″). They weight in at 62 kg (137 lbs), which is obviously highly individual, and reach an average age of 75 years.
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).
