How many baby Pale field rats are in a litter?
A Pale field rat (Rattus tunneyi) usually gives birth to around 5 babies.
Each of those little ones spend around 22 days as a fetus before they are released into the wild. Upon birth, they weight 4 grams (0.01 lbs) and measure 4.2 cm (0′ 2″). They are a member of the Muridae family (genus: Rattus). An adult Pale field rat grows up to a size of 15.1 cm (0′ 6″).
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 pale field rat, (Rattus tunneyi), is a small mammal endemic to Australia. They are a nocturnal and herbivorous rodent who reside throughout the day in shallow burrows made in loose sand. Once widespread, the range has become greatly reduced and it is restricted to the grasslands, sedges, and cane-fields at the north and east of the continent. The fur is an attractive yellow-brown colour, with grey or cream at the underside, and this medium-sized rat has a tail shorter than body.
