Gould’s mouse size: How big do they get?

How big does a Gould’s mouse get? Here is an overview over the average adult age:

A grown Gould’s mouse (Pseudomys gouldii) reaches an average size of 10.8 cm (0′ 5″).

When born, they have an average size of 0 cm (0′ 0″). A full-grown exemplary reaches roughly 49 grams (0.11 lbs). The Gould’s mouse (genus: Pseudomys) is a member of the family Muridae.

As a reference: Humans reach an average body size of 1.65m (5′ 5″) while carrying 62 kg (137 lbs). A human woman is pregnant for 280 days (40 weeks) and on average become 75 years old.

The average adult size of a Gould's mouse is  (0' 5

Gould’s mouse (Pseudomys gouldii) lived in eastern inland Australia, and was named after John Gould. It was slightly smaller than a black rat, and quite social, living in small family groups that sheltered by day in a nest of soft, dry grass in a burrow. It usually dug burrows at a depth of 15 cm under bushes. Gould’s mouse was common and widespread before European settlement, but disappeared rapidly after the 1840s, perhaps being exterminated by cats. Alternatively, it may have been out-competed by the introduced rats and mice, succumbed to introduced diseases or been affected by grazing stock and changed fire regimes. Despite extensive survey work in its known range, the last specimens were collected in 1856–57, and it is presumed to be extinct.There is some speculation that this species was in fact an eastern population of the Shark Bay mouse (Pseudomys fieldi). Once the Alice Springs mouse was thought to be extinct but with genetic testing in 1998 scientists confirmed that the Alice Springs mouse was also the Shark Bay mouse, and this could also one day happen between Gould’s mouse and the Shark Bay mouse.

Not that size really matters, but it makes things comparable. So here are a couple of animals that are as big as Gould’s mouse:
