List of adaptive radiated marsupials by form

This is a list of adaptive radiated marsupials by form; they are adaptively radiated marsupial species equivalent to the many niche-types of non-marsupial mammals. Many of the surviving species are from Australia. There are unique types, for example the extinct genus Nototherium, a 'rhinoceros-type'.

The new world has the common opossum, also a unique form.

Even before the mid-19th century and Charles Darwin's time, biogeographers understood speciation and animal niches. A supreme example that became known to Darwin as sailing ships traveled the world is the New Zealand flightless, ground-dwelling, worm-eating kiwi, a bird, but a species in a mammal-niche.
