               Are there marsupials
               outside of Australia?

                In short, yes. While the marsupials of
                Australia are particularly famous, as they
                are the predominant mammal type found
                there, marsupials can also be found in
                the Americas and islands surrounding
                Australia. There are around 334 species
                in the world, around 200 on the Australian
                continent and around 100 in Central, South

                able to swoop down and carry off the marmosets with ease should

                upon the small primates, so they must stay vigilant and always be
                on the lookout. They are listed as being of Least Concern by the
                IUCN Red List, although their numbers are decreasing due to loss
                of habitat and encroachment of humans.
