The delicate mouse is one of the smallest rodents in Australia. It has a light body, large eyes, a long tail, and soft fur.
The delicate mouse differs from other Australian rodents by its very small size and weight. It is important for nature as a seed disperser of plants and as food for snakes, birds, and other predators.
