 All ningaui are nocturnal hunters of invertebrates.In appearance they resemble mice or similar small rodents, but can be distinguished by their pointed snouts.The genus "Ningaui" was one of the last of the Australian marsupial genera to be erected; this occurred with the surprise discovery of the Wongai ningaui ("N. ridei") and the Pilbara ningaui ("N. timealeyi") in 1975.
