Litter Size

How many babies does a Spinifex hopping mouse have at once? (litter size)

How many baby Spinifex hopping mouses are in a litter?

A Spinifex hopping mouse (Notomys alexis) usually gives birth to around 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 2 grams (0 lbs) and measure 3.5 cm (0′ 2″). They are a member of the Muridae family (genus: Notomys). An adult Spinifex hopping mouse grows up to a size of 10 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 average litter size of a Spinifex hopping mouse is 4

The spinifex hopping mouse (Notomys alexis), also known as the tarkawara or tarrkawarra, occurs throughout the central and western Australian arid zones, occupying both spinifex-covered sand flats and stabilised sand dunes, and loamy mulga and melaleuca flats.The population fluctuates greatly: in normal years it is sparsely distributed and probably confined to sandy country; after rain the population explodes and spreads to other types of habitat for a time. They are mostly seen at night, bounding across open ground on their large hind feet, with tails extended and the body almost horizontal. As semi-fossorial, burrowing surface foragers, the tiny hopping mice spend a great deal of energy not just foraging for food, but also transporting it back to their burrows. In fact, it was found that the total energy spent on transporting food in relation to energy investment on burrows far outweighed any other similar type of species (White, 2006).
