Pseudomys is a genus of rodents commonly known as the bush mice. These small mammals are native to Australia and New Guinea, where they inhabit a variety of environments, including forests, grasslands, and scrublands. They are characterized by their long tails, large ears, and soft fur, which helps them adapt to their surroundings. Bush mice are primarily nocturnal and feed on seeds, fruits, and insects. They play an important role in their ecosystems by aiding in seed dispersal and serving as prey for various predators. Conservation efforts are essential to protect their habitats from threats such as habitat loss and invasive species.
