As with a number of dasyurid species, the males live for only one year, dying after a period of frenzied mating.

The following is a phylogenetic tree based on mitochondrial genome sequences:[3] Thylacinus (thylacine) Myrmecobius (numbat) Sminthopsis (dunnarts) Phascogale (wambengers) Dasyurus (quolls) The genus consists of the following three species: Mating generally happens between May and July.

Females give birth to about 6 young ones about 30 days after mating.

Instead, they form temporary folds of skin - sometimes called a "pseudo-pouch" [3] around the mammary glands during pregnancy.

Females live for about 3 years, and generally produce one litter.
