How many babies does a Mitchell’s hopping mouse have at once? (litter size)

How many baby Mitchell’s hopping mouses are in a litter?

A Mitchell’s hopping mouse (Notomys mitchellii) usually gives birth to around 3 babies.

Each of those little ones spend around 35 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 Mitchell’s hopping mouse grows up to a size of 11.3 cm (0′ 5″).

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 Mitchell's hopping mouse is 3

Mitchell’s hopping mouse (Notomys mitchellii) is the largest extant member of the genus Notomys, weighing between 40 and 60 g (1.4 and 2.1 oz). N. mitchellii is a bipedal rodent with large back legs, similar to a jerboa or kangaroo rat. The species occurs throughout much of semi-arid Southern Australia, and appears to be particularly common on the Eyre Peninsula, South Australia. Typical habitat for N. mitchellii appears to be mallee shrublands on sandy dune systems. The species is currently considered to be unthreatened, but its range has been reduced through habitat disturbance and destruction associated with European settlement in Australia.Individuals are a sandy grey colour, with white chest hairs and a paler underbelly. The tail of the species is long and has the characteristic hopping mouse brush at the tip. This tail morphology is thought to aid balance when travelling at speed. Being nocturnal, Notomys mitchellii shelters during the day in typical hopping mouse burrows; a small number of interconnected, vertical shafts, burrowing deep into the dune. Up to eight animals, different ages and sex, have been found in a single burrow.N. mitchellii is known to have a lifespan of up to five years in the laboratory and this is thought to be a strategy evolved to combat the breeding-constraints of lengthy periods of drought. It has also been found that this species is less able to cope with water deprivation than other species of the genus. Notomys mitchellii produces concentrated urine to conserve water, but in a different way to more arid-dwelling rodents. The diet of N. mitchellii is also thought to consist of more roots and green matter than that of other species of the genus: animals captured in drought conditions had stomach contents consisting of some 85% roots, 11% green leaf and 4% seed.
