Wombats Koala Possums Wallabies and Kangaroos: Diprotodontia

Diprotodontia have evolved to take advantage of almost every terrestrial habitat. This expansion into different habitats is called radiation. Kangaroos graze on grasslands, cuscus and tree kangaroos live in tropical rainforest trees. Some pygmy possums live in the mountains where it snows six months out of the year. Despite the variety of habitats where members of this order can be found, some individual species live in very restricted areas, because they have evolved to use a very specific set of resources.
