 It is known that the dunnart stores all its fat in its tail.They usually move about by running smoothly on all four legs, sometimes with sudden short stops, during which they often squat with the forebody slightly elevated.The sandhill dunnart is the second largest of the 19 dunnart (Sminthopsis) species, with an adult body mass of 35g (females) to 44g (males); only the Julia Creek dunnart (S. douglasi; 40–70 g) is larger.
