Peramelemorphia is an order of marsupials that includes bandicoots and bilbies. These small to medium-sized mammals are primarily found in Australia and New Guinea. They are characterized by their elongated snouts, strong hind legs, and a pouch for carrying their young. Bandicoots are nocturnal and omnivorous, feeding on insects, small animals, and plant material. They play an important role in their ecosystems by helping to control insect populations and aerate the soil through their digging activities. Conservation efforts are ongoing to protect some species of bandicoots that are threatened by habitat loss and introduced predators.
