The Musky Rat-kangaroo (Hypsiprymnodon moschatus) is a marsupial species found in the rainforests of New Guinea and northeast Australia. Some scientists place this species as a subfamily (Hypsiprymnodontinae) of the family Potoroidae. The most recent classification places it in its own family Hypsiprymnodontidae. It is the smallest macropod that is quadrupedal and only diurnal. The Musky Rat-kangaroo is approximately 9.05 in (23) cm long, and eats fallen fruit as well as small invertebrates.
It moves by extending its forelegs and then bringing both of its hind legs forward.
The mothers have two to three babies, who stay in her pouch for about 21 weeks.
