How many baby Fawn hopping mouses are in a litter?
A Fawn hopping mouse (Notomys cervinus) usually gives birth to around 2 babies.
Each of those little ones spend around 41 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 Fawn 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 fawn hopping mouse (Notomys cervinus) is a rodent native to the central Australian desert. Like all hopping mice it has strong front teeth, a long tail, dark eyes, big ears, well-developed haunches and very long, narrow hind feet. It weighs between 30 and 50 g (1.1 and 1.8 oz). (Compare with the common house mouse, at 10 to 25 g (0.35 to 0.88 oz).)The coloration of the fawn hopping mouse varies from pale pinkish-fawn to grey on the upper parts, and white underneath. The tail is 120 to 160 mm (4.7 to 6.3 in) long, bicoloured (white underneath, darker below), and ends in a dark brush. The ears and round, dark eyes are particularly large, and the whiskers even more so: 65 mm (2.6 in) in a creature that is only 95 to 120 mm (3.7 to 4.7 in) long.The favoured habitat is the sparsely vegetated arid gibber plains and claypans of the Lake Eyre Basin, including parts of northern South Australia, far south-western Queensland and possibly the Northern Territory, though this last is uncertain. Records from the late 19th century show that its former range was more extensive including western New South Wales.Breeding is thought to be opportunistic. In captivity, gestation is about 40 days and between one and five fully furred young are born.Fawn hopping mice live in small family groups of two to four individuals. During the day, they shelter in burrows which are simpler and shallower than those of the sand-dwelling dusky hopping mouse but nevertheless up to a metre deep with between one and three entrances. At night, they forage outwards for hundreds of metres, searching for seeds, and also taking green shoots and insects if the opportunity presents itself. As with other hopping mice, they do not need to drink, though they can metabolise highly saline water if it is available.The fawn hopping mouse is classified as vulnerable. The causes of its decline are unknown, but assumed to be habitat degradation, competition for food with introduced species, and predation by introduced cats and foxes.
