[6] D. blythi is widely distributed, having been observed during different expeditions in the north-western, central, and south-western areas of the arid zone of Australia.

[7] D. blythi is an opportunistic carnivorous marsupial eating a wide range of invertebrates, frogs, reptiles, and small mammals.

Once males find a home range, they become sedentary due to increased fitness by remaining in a familiar area rather than moving to new, uncharted territory.

Their monoestry is thought to arise from increased access to larger and more reliably available prey, such as small mammals and reptiles, which are inaccessible by smaller dasyurids.

Gestation ranges from 30 to 48 days, being extended by factors such as scarce food resources, low temperatures, and frequency of torpor.

[13][4] After birth, the young suckle between 12 and 15 weeks by hanging below the female's body due to a reduced pouch, a pair of lateral flaps.

[9] D. blythi digs deep burrows, providing protection from the extremes of climate and potentially the predation by introduced European species to which other small and medium-sized desert mammals often fall prey.

Its benefit is felt both in summer and winter seasons, as it allows for reduction of endogenous heat production and maintenance of energy spent to be below basal metabolic rate.

[5] To provide further protection and future proliferation, animal surveys using targeted trapping and patch burning programs are used to create an ideal habitat.
