The long-tailed mouse is a small rodent that lives only in the forests of Tasmania. It has a long body and a very long tail that helps maintain balance during fast running and jumping.
The long-tailed mouse differs from other mice with its particularly long tail and lives only in Tasmania. It helps spread plant seeds and serves as food for snakes, owls, and marsupial predators.
