Upon birth, they weight 2 grams (0 lbs) and measure 3.7 cm (0′ 2″). They are a member of the Muridae family (genus: Apodemus). An adult Taiwan field mouse grows up to a size of 9.1 cm (0′ 4″).
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.
The Taiwan field mouse, also called Formosan wood mouse (Apodemus semotus), is a species of rodent in the family Muridae.It is found only in Taiwan.The Taiwan field mouse is primarily distributed in the montane region between 1,400 and 3,000 m. They inhabit various habitat types, such as natural or planted forests, grasslands, farms, and campsites, and are omnivorous feeding on plants, insects and fungi.Based on morphological measurements, it has been suggested that the Taiwan field mouse is not different from the South China field mouse (Apodemus draco), and should not be considered as a separate species.The Taiwan field mouse is sexually dimorphic, with male generally larger than females (male: 25.6 ± 0.5 g; female: 23.8 ± 0.5 g). Mark-capture-recapture data suggest that their life span may be less than 1 year in the wild.
