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).
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.
