How many baby Desert mouses are in a litter?
A Desert mouse (Pseudomys desertor) usually gives birth to around 3 babies.
Each of those little ones spend around 28 days as a fetus before they are released into the wild. Upon birth, they weight 4 grams (0.01 lbs) and measure 3.3 cm (0′ 2″). They are a member of the Muridae family (genus: Pseudomys). An adult Desert mouse grows up to a size of 8.8 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 desert mouse (Pseudomys desertor), also known as the brown desert mouse, is a species of rodent in the family Muridae. It is endemic to Australia. The first desert mouse specimen was collected by Australian zoologist Gerard Krefft on the Blandowski Expedition in 1856-57, between Gol Gol Creek and the Darling River.
