The red-cheeked marsupial mouse is a small predatory marsupial mammal. It lives in Australia and New Guinea, hunts insects at night, and carries its young in a pouch on its belly.
The red-cheeked marsupial mouse differs from related species with its bright red patches on the cheeks. It helps maintain balance in nature by eating a large number of insects.
