How many babies does a Northern nail-tail wallaby have at once? (litter size)

How many baby Northern nail-tail wallabys are in a litter?

A Northern nail-tail wallaby (Onychogalea unguifera) usually gives birth to around 1 babies.

Upon birth, they weight 22 grams (0.05 lbs) and measure 13.5 cm (0′ 6″). They are a member of the Macropodidae family (genus: Onychogalea). An adult Northern nail-tail wallaby grows up to a size of 52.5 cm (1′ 9″).

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 northern or sandy nail-tail wallaby refers to Onychogalea unguifera, a species of macropod found across northern Australia on arid and sparsely wooded plains.The largest species of the genus Onychogalea, it is a solitary and nocturnal herbivorous browser that selects its food from a wide variety of grasses and succulent plant material. Distinguished by a slender and long-limbed form that resembles the typical and well known kangaroos, although their standing height is shorter, around half of one metre, and their weight is less than nine kilograms. As with some medium to large kangaroo species, such as Macropus rufus, they have an unusual pentapedal motion at slow speeds by stiffening the tail for a fifth limb. When fleeing a disturbance, they hop rapidly with the tail curled back and repeatedly utter the sound “wuluhwuluh”. Their exceptionally long tail has a broad fingernail-like protuberance beneath a dark crest of hair at its end, a peculiarity of the genus that is much broader than the other species. The name unguifera, meaning claw, is a reference to this extraordinary attribute, the purpose of which is unknown.Like the other species of the genus, they retire for the day in a shallow depression, but if disturbed they flee rapidly to find refuge in a hollow tree or thicket. Unlike the rare bridled nailtail O. fraenata, once widespread and currently rare, the northern nail-tail wallaby is not a threatened species. The other member of the genus Onychogalea, the crescent nail-tail O. lunata of the centre and west of Australia, probably became extinct in the mid twentieth century.
