The sugar glider is a small, omnivorous, arboreal, and nocturnal gliding possum. The common name refers to its predilection for sugary foods such as sap and nectar and its ability to glide through the air, much like a flying squirrel. They have very similar habits and appearance to the flying squirrel, despite not being closely related—an example of convergent evolution. The scientific name, Petaurus breviceps, translates from Latin as "short-headed rope-dancer", a reference to their canopy acrobatics.
Phalangeriformes is a paraphyletic suborder of about 70 species of small to medium-sized arboreal marsupials native to Australia, New Guinea, and Sulawesi. The species are commonly known as possums, gliders, and cuscus. The common name "possum" for various Phalangeriformes species derives from the creatures' resemblance to the opossums of the Americas. However, although opossums are also marsupials, Australasian possums are more closely related to other Australasian marsupials such as kangaroos.
Leadbeater's possum is a critically endangered possum largely restricted to small pockets of alpine ash, mountain ash, and snow gum forests in the Central Highlands of Victoria, Australia, north-east of Melbourne. It is primitive, relict, and non-gliding, and, as the only species in the petaurid genus Gymnobelideus, represents an ancestral form. Formerly, Leadbeater's possums were moderately common within the very small areas they inhabited; their requirement for year-round food supplies and tree-holes to take refuge in during the day restricts them to mixed-age wet sclerophyll forest with a dense mid-story of Acacia. The species was named in 1867 after John Leadbeater, the then taxidermist at the Museum Victoria. They also go by the common name of fairy possum. On 2 March 1971, the State of Victoria made the Leadbeater's possum its faunal emblem.
The squirrel glider is a nocturnal gliding possum. The squirrel glider is one of the wrist-winged gliders of the genus Petaurus.
The genus Petaurus contains flying phalangers or wrist-winged gliders, a group of arboreal possums native to Australia, New Guinea, and surrounding islands. There are eight species: the sugar glider, savanna glider, Krefft's glider, squirrel glider, mahogany glider, northern glider, yellow-bellied glider and Biak glider.
The patagium is a membranous body part that assists an animal in obtaining lift when gliding or flying. The structure is found in extant and extinct groups of flying and gliding animals including bats, theropod dinosaurs, pterosaurs, gliding mammals, some flying lizards, and flying frogs. The patagium that stretches between an animal's hind limbs is called the uropatagium or the interfemoral membrane.
A number of animals are capable of aerial locomotion, either by powered flight or by gliding. This trait has appeared by evolution many times, without any single common ancestor. Flight has evolved at least four times in separate animals: insects, pterosaurs, birds, and bats. Gliding has evolved on many more occasions. Usually the development is to aid canopy animals in getting from tree to tree, although there are other possibilities. Gliding, in particular, has evolved among rainforest animals, especially in the rainforests in Asia where the trees are tall and widely spaced. Several species of aquatic animals, and a few amphibians and reptiles have also evolved this gliding flight ability, typically as a means of evading predators.
There are many different types of gliding possum, sometimes referred to as volplane possum, flying phalangers, or simply as gliders, endemic to Australia and New Guinea. Taxonomically, gliding possums occupy three genera.
The mahogany glider is an endangered gliding possum native to a small region of coastal Queensland in Australia.
The striped possum or common striped possum is a member of the marsupial family Petauridae. It is found mainly in New Guinea. The species is black with three white stripes running head to tail, and its head has white stripes that form a 'Y' shape. It is closely related to the sugar glider, and is similar in appearance.
The yellow-bellied glider, also known as the fluffy glider, is an arboreal and nocturnal gliding possum that lives in native eucalypt forests in eastern Australia, from northern Queensland south to Victoria.
The great-tailed triok is a species of marsupial in the family Petauridae. It is found in West Papua and Papua New Guinea. Its natural habitat is subtropical or tropical dry forests.
Dactylopsila is a genus of marsupials in the family Petauridae, native to New Guinea, the Cape York peninsula of Australia, and other close islands. Members of this genus are known as trioks or striped possums, though the latter name is usually used for D. trivirgata.
Tate's triok, also known as the Fergusson Island striped possum, is a species of marsupial in the family Petauridae. It is endemic to Papua New Guinea. Its natural habitat is subtropical or tropical dry forests.
The northern glider is a species of marsupial in the family Petauridae. It is endemic to Papua New Guinea, becoming known to science in 1981 after being discovered in the Torricelli Mountains. This species has been found in primary, mid-montane tropical moist forests. It is also known from rural gardens close to forest. The northern glider is Critically Endangered because its occurrence is less than 100 km2, all individuals are located within a single area, and a continuing decline of its habitat quality due to deforestation and human encroachment. They also face a major threat from hunting.
Petauroidea is a superfamily of marsupials from Australia and New Guinea. It is part of the suborder Phalangeriformes within the order Diprotodontia, which also includes, among others, wombats, kangaroos, cuscuses. The superfamily Phalangeroidea, including cuscuses and brushtail possums and pygmy possums, is the immediate sister group of the Petauroidea. The earliest fossils from this superfamily are from the Oligocene of the Geilston Bay fossil site in Tasmania.
