The woylie is a small marsupial with adult males weighing 1–1.8 kg and adult females weighing 0.75–1.5 kg. The head and body length is 300–360 mm for males and 280–350 mm for females; the tail length is 250–360 mm. The fur is grey to greyish brown on the back and flanks, and pale greyish on the undersides. The tail is dark and has a distinctive black brush at the end. Woylies carry nesting material in the curled tip of their tail which is prehensile (adapted for grasping). Other common names include the brush-tailed bettong and the brush-tailed rat-kangaroo. Woylie (‘Woli’ according to Noongar orthography) is a Noongar Aboriginal name for this species. Other Indigenous names include Woylyer and Karpitchi.
