In the words of Charles Darwin, who dragged a fleeing specimen from its refuge, the long-nosed potoroo (Potorous tridactylus) “is an animal, as big as a rabbit, but with the figure of a kangaroo”. Indeed, this compact marsupial belongs to a family sometimes referred to as the rat-kangaroos . The soft, loose fur is grey to brown above and light grey below, while the partially prehensile tail is sometimes tipped with white. The ears are short and rounded, and as its name suggests, this species has a long, tapering nose, with a naked tip. In adult specimens, the nose length is greater than the rear foot length, unlike the related long-footed potoroo, which has a longer rear foot than nose length. The hind-limbs are well developed and heavily muscled like those of a kangaroo, while the short but muscular fore-limbs bear small paws, with forward-pointing spatulate claws used for digging.
