The brown marsupial mouse is a small predatory marsupial mammal. The animal inhabits the forests of eastern Australia and leads a nocturnal lifestyle.
The brown marsupial mouse differs from related species in that males die after the first breeding season due to severe stress. It is important for nature because it regulates the number of insects in forests.
