Like other members of its genus, it is characterized by a short, intense breeding period that is fatal for males due to severe physiological stress. This recently described species is distinctively marked by its grayish-silver head and primarily feeds on insects.
help Silver-headed antechinus FAQ
When was the silver-headed antechinus discovered?
The silver-headed antechinus (Antechinus argentus) was officially identified and described as a new species by science in 2015. It was discovered by a team of researchers in the isolated, elevated forests of central Queensland, Australia.
Why is it called the silver-headed antechinus?
The animal gets its common name from the distinct, silvery-grey fur that covers its head and neck, contrasting with its mostly brown body. This feature helped distinguish it from other closely related marsupials in the Antechinus genus.
What is unique about the mating habits of the silver-headed antechinus?
Like other species in its genus, the male silver-headed antechinus lives for less than a year and dies shortly after its intense, frenzied mating season. The physiological stress of this mating period causes a fatal immune system collapse due to cortisol overload.
Is the silver-headed antechinus endangered?
Yes, the silver-headed antechinus is currently listed as an endangered species under Australian environmental law. Its small population is highly threatened by habitat loss caused by climate change-induced wildfires and invasive predators like feral cats.
