How many babies does a Long-tailed mouse have at once? (litter size)

How many baby Long-tailed mouses are in a litter?

A Long-tailed mouse (Pseudomys higginsi) usually gives birth to around 2 babies.With 2 litters per year, that sums up to a yearly offspring of 4 babies.

Each of those little ones spend around 32 days as a fetus before they are released into the wild. Upon birth, they weight 5 grams (0.01 lbs) and measure 19.1 cm (0′ 8″). They are a member of the Muridae family (genus: Pseudomys). An adult Long-tailed mouse grows up to a size of 12.8 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 long-tailed mouse (Pseudomys higginsi) is a native Australian mammal in the Order Rodentia and the Family Muridae. It is found only on the island of Tasmania. The long-tailed mouse is an omnivore that feeds on insects and a range of plants. It is found in forested areas, particularly in sub-alpine scree, and may live in burrows.The species reaches a weight of about 70 grams. It is distinguished from other species by its two-tone tail, which is white on the underside and dark above. The tail is 1.3 times longer than the head and body combined. It is stipulated that P.higginsi uses its tail for balance while leaping in habitat such as boulder screes.Fossils of this species have been found in Cloggs Cave, Buchan in eastern Victoria and were identified by palaeontologist Jeanette Hope. The date for the remains based on C-14 dating were between 12-20,000 years old.
