The New Holland mouse is a small rodent that lives only in Australia. It has gray-brown fur, a long tail, and large eyes adapted to nocturnal life.
The New Holland mouse differs from other Australian rodents by its special tooth shape and love for dense coastal thickets. It is important for nature because it disperses plant seeds and serves as food for snakes and owls.
