Gilbert’s Potoroo (Potorous gilbertii) was a ratlike marsupial fungivore which lived in great numbers throughout south-west Australia—particularly around King George Sound. The animals were discovered to science by the great naturalist George Gilbert in 1840. Unfortunately the potoroo proved to be extremely vulnerable to introduced predators such as foxes and dingoes. After an exhaustive search in the 1970s failed to find any living specimens of the creature (which had not been seen in decades) the unlucky mammals were deemed extinct, and thus Gilbert’s potoroo vanished forever from the—[needle comes off of sad record]—wait! actually this strange rodent-like/kangaroo-like creature was rediscovered in 1994.
After nearly two decades during which time the potoroos were presumed dead, a small population was found living in a remote and inaccessible scrubland beside Two Peoples Bay in Western Australia. The area was proclaimed a nature preserve and humankind leapt into action to save the beleaguered potoroo.
Yet, it has not been easy to relaunch the peculiar animal. The creatures live on truffle-like fungi, which they dig up with their three toed paws (each digit has a sharpened digging claw). The male potoroos are susceptible to balanoposthitis, a bacterial disease which disfigures the genitals with inflammation and leaves the creatures unable to reproduce. Also the animals seem to be extremely sensitive to cryptococcosis, a dangerous fungal disease which can lead to coughing and respiratory failure.
Fortunately, patient zookeepers, rangers, and volunteers have been working to help Gilbert’s potoroo overcome these alarming hurdles. The world population now numbers nearly 70—but the peculiar marsupial digger remains one of the planet’s most endangered mammals.
