The Alexandrian false marsupial mouse is a small predatory marsupial mammal. It lives in the rocky areas of northern Australia and hunts insects at night.
This species differs from related marsupial mice by the thickened base of the tail and adaptation to life among rocks. It helps maintain balance in nature by eating insects.
