Physical characteristics and distribution

Head and body length is 350-450 mm, tail 210-300. Coloration varies from mostly gray, olive brown or dark rufous brown on top, with a less common black phase. This occurs in both sexes, and in litters with more commonly colored individuals. All color phases have prominent white spots on the back and sides. The coat is generally short, thick and soft. Dasyurus viverrinus is unique in the genus in that the first toe on the hind foot is lacking. The foot pads are granulate. The pouch is shallow, formed by a patch of skin which covers the six to eight mammae. Dasyurus viverrinus prefers dry forest and open country and is primarily terrestrial, though it is a good climber. They are also mostly nocturnal, though they have been seen by day.

The main commponent of its diet is invertebrates, especially agricultural pests such as the cockchafer beetle and corbie grub. Carrion and some fruits are also eaten.

Females are polyestrous, reaching a peak in late May and early June, with gestation lasting between 20 and 24 days. The young detach from the nipples at 8 weeks and are independent by eighteen weeks. The maximum known life span of Dasyurus viverrinus is 6 years 10 months.

Dasyurus viverrinus was common in South Australia, New South Wales and Victoria, but
today it probably survives only in Tasmania.
