description Dusky antechinus Overview
The dusky antechinus is a small carnivorous marsupial native to southeastern Australia, including Tasmania, and was described by George Waterhouse in 1840. Despite its mouse-like appearance, it is not a rodent and belongs to the dasyurid family, whose members include quolls and the Tasmanian devil. It feeds chiefly on invertebrates and is the largest species traditionally placed in Antechinus, making it relevant to studies of Australian marsupial ecology and reproduction.
help Dusky antechinus FAQ
Is the dusky antechinus a mouse?
No. It is the marsupial Antechinus swainsonii in the dasyurid family, which also includes quolls, rather than a rodent family.
Where does the dusky antechinus live?
The dusky antechinus is native to southeastern Australia, including Tasmania. It is associated with ground cover and dense vegetation that provide shelter for this small carnivorous marsupial.
Why is the dusky antechinus breeding season unusual?
Male antechinuses undergo an intense, synchronized breeding season and commonly die after mating, a strategy known as semelparity. This creates a sharp seasonal change in the age and sex structure of populations.
Who described the dusky antechinus, and when?
George Waterhouse described the dusky antechinus in 1840. That date marks its formal scientific description, not the beginning of the species' existence in Australia.
