A possum (plural form: possums) is any of about 70 small- to medium-sized arboreal marsupial species native to Australia, New Guinea, and Sulawesi (and introduced to New Zealand and China). The name derives from their resemblance to the opossums of the Americas (the name is from Algonquian ''wapathemwa'', not Greek or Latin, so the plural is ''possums'', not ''possa'' or ''possi''). Possums are quadrupedal diprotodont marsupials with long tails. The smallest possum, indeed the smallest diprotodont marsupial, is the Tasmanian pygmy possum, with an adult head-body length of and a weight of . The largest are the two species of bear cuscus which may exceed . Possums are typically nocturnal and at least partially arboreal. The various species inhabit most vegetated habitats, and several species have adjusted well to urban settings. Diets range from generalist herbivores or omnivores (the common brushtail possum) to specialist browsers of eucalyptus (greater glider), insectivores (mountain pygmy possum) and nectar-feeders (honey possum). ==Classification== About two-thirds of Australian marsupials belong to the order Diprotodontia, which is split into three suborders: the Vombatiformes (wombats and the koala, four species in total); the large and diverse Phalangeriformes (the possums and gliders) and Macropodiformes (kangaroos, potoroos, wallabies and the musky rat-kangaroo).
