The genus name Sminthopsis was published by Oldfield Thomas in 1887, the author noting that the name Podabrus that had previously been used to describe the species was preoccupied as a genus of beetles. [2] The type species is Phascogale crassicaudata , published by John Gould in 1844.

There are 19 species, [note 1] all of which occur in Australia and New Guinea: [3]

The genus is referred to by their common name of dunnarts.

Description

A male dunnart's Y chromosome is the smallest known mammalian Y chromosome. [4]

The Dasyuridae are a family of marsupials native to Australia and New Guinea, including 71 extant species divided into 17 genera. Many are small and mouse-like or shrew-like, giving some of them the name marsupial mice or marsupial shrews, but the group also includes the cat-sized quolls, as well as the Tasmanian devil and the extinct thylacine. They are found in a wide range of habitats, including grassland, underground, forests, and mountains, and some species are arboreal or semiaquatic. The Dasyuridae are often called the 'marsupial carnivores', as most members of the family are insectivores.

Dates in days

The house mouse has a gestation period of 19 to 21 days. Key events in mouse brain development occur both before and after birth, beginning with peak neurogenesis of the cranial motor nuclei 9 days after conception, up to eye opening which occurs after birth and about 30 days after conception.
