The musky rat-kangaroo (Hypsiprymnodon moschatus) is a marsupial species found only in the rainforests of northeast Australia. Although some scientists place this species as a subfamily (Hypsiprymnodontinae) of the family Potoroidae, the most recent classification places it in the family Hypsiprymnodontidae with prehistoric rat-kangaroos.
The generic name combines the Ancient Greek hyps- (‘high’), prymnos (πρυμνός ‘hindmost’), and odōn (‘teeth’).[3] Its specific name, moschātus, is scientific Latin for ‘musk’.
It is the smallest macropod that is quadrupedal and only diurnal. The musky rat-kangaroo is about 21 to 34 cm long with a 6.5- to 12.3-cm-log hairless tail, weighs between 332 and 680 g,[4] and eats fallen fruit and large seeds, as well as small invertebrates.[5]
It moves by extending its body and then bringing both of its hind legs forward, and uses an opposable digit on the hind foot to climb trees.[5]
Living fossil
The rat-kangaroo has a number of unusual traits that are seen as linking it to more primitive marsupial ancestors. For example, it has reptile-like scales on its feet and tail, engages in a more primitive hopping behavior than most of its kangaroo cousins, and 5 toes on each foot.
