Brown Antechinus

Antechinus stuartii

Least Concern

The species is abundant and widely distributed; it faces no significant short-term risk.

Spotted something wrong?

The brown antechinus is a small carnivorous marsupial of eastern Australia, the size of a mouse but with the dentition of a predator. It hunts invertebrates and the occasional small vertebrate on the ground and among fallen logs. It is famous for its extreme reproductive strategy: the entire male population dies a few weeks after a single mating season, a phenomenon of such precise synchrony that the species is a model in the biology of ageing.

Fun facts

  • Every male in the population dies after a single mating season: for two or three weeks they mate almost without stopping, up to twelve hours at a time, and the surge of cortisol collapses their immune system. Not one reaches a year old.
  • The synchrony is astonishing: the breeding season is triggered on the same dates every year, tuned to day length, and within days an entire population is left without males.
