The Ooldea dunnart (Sminthopsis ooldea), also called Troughton's dunnart after the person who found the species, is an Australian marsupial similar to the hairy-footed dunnart. It is greyish-yellow on its upper body and white on the underside with dark patches on its crown, forehead and in front of the eyes, and a pink thinly furred carrot-shaped tail. Its total length is 11.5–17.3 cm (4.5–6.8 in); its average body length is 5.5–8 cm (2.2–3.1 in) with a tail of 6–9.3 cm (2.4–3.7 in). Its ear length is 14–17 mm (0.55–0.67 in). It weighs between 10 and 18 g (0.35 and 0.63 oz).

Distribution and habitat

The Ooldea dunnart is found from the Tanami Desert in the Northern Territory, south to Ooldea in South Australia and east to neighbouring areas of Western Australia. The type of habitat it inhabits includes arid eucalypt and acacia woodlands, heathlands mallee scrub and hummock grasslands, low shrubland, open scrub and tall open shrubland.

Social organisation and breeding

The Ooldea dunnart has eight young between September and November but, since the species is not much studied, not much more is known. It is nocturnal and has been found in burrows and hollow logs.

Diet

It is believed, from evidence gathered, that this species eats insects.

The Dasyuridae are a family of marsupials native to Australia and New Guinea, including 69 extant species divided into 21 genera. Many are small and mouse-like or shrew-like, giving some of them the name marsupial mice or marsupial shrews, but the group also includes the cat-sized quolls, as well as the Tasmanian devil. They are found in a wide range of habitats, including grassland, underground, forests, and mountains, and some species are arboreal or semiaquatic. The Dasyuridae are often called the 'marsupial carnivores', as most members of the family are insectivores.

The fat-tailed dunnart is a species of mouse-like marsupial of the Dasyuridae, the family that includes the little red kaluta, quolls, and the Tasmanian devil. It has an average body length of 60–90 millimeters (2.4–3.5 in) with a tail of 45–70 millimeters (1.8–2.8 in). Ear length is 14–16 millimeters (0.55–0.63 in). One of the smallest carnivorous marsupials, its weight varies between 10–20 grams (0.35–0.71 oz). The tail becomes fat a few mm from the proximal end and remains so right up to the tip. The dunnart has trichromat vision, similar to some other marsupials as well as primates but unlike most mammals which have dichromat vision. The dunnart is often eaten by other carnivores, including invasive foxes and cats, as well as other feral animals that live among its environment.
