Gliding Possum
There are many different types of gliding possum, sometimes referred to as :wikt:volplane, volplane possum, flying phalangers, or simply as gliders, endemic to Australia and New Guinea. Taxonomically, gliding possums occupy three genera.

Yellow-bellied Glider
The yellow-bellied glider (''Petaurus australis''), 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. Habitat The yellow-bellied glider inhabits forests and woodlands in eastern Australia and is found at a range of altitudes from sea level to 1400 metres. In North Queensland, the sub-species occurs at altitudes over 700 m above sea level. With natural discontinuities and habitat clearings, there are 13 different populations in three distinct places to find this glider in North Queensland. One population resides on Mount Windsor Tableland, another on Mount Carbine Tableland, and the third lives in a linear habitat going from Atherton to Kirrama on the Atherton Tableland. These three populations together are estimated to contain around 6000 individual gliders. With their habitat in danger, the yellow-bellied glider is classified as uncommon to ra ...

Patagia
The patagium (: patagia) 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 (including birds and some dromaeosaurs), pterosaurs, gliding mammals, some flying lizards, and flying frogs. The patagium that stretches between an animal's hind limbs is called the uropatagium (especially in bats) or the interfemoral membrane. Bats In bats, the skin forming the surface of the wing is an extension of the skin of the abdomen that runs to the tip of each digit, uniting the forelimb with the body. The patagium of a bat has four distinct parts: #Propatagium: the patagium present from the neck to the first digit. #Dactylopatagium: the portion found within the digits. #Plagiopatagium: the portion found between the last digit and the hindlimbs. #Uropatagium: the posterior portion of the flap between the two hindlimbs. Pterosaurs In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gliding Flight
Gliding flight is heavier-than-air flight without the use of thrust; the term volplaning also refers to this mode of flight in animals. It is employed by flying and gliding animals, gliding animals and by aircraft such as glider (aircraft), gliders. This mode of flight involves flying a significant distance horizontally compared to its descent and therefore can be distinguished from a mostly straight downward descent like a round parachute. Although the human application of gliding flight usually refers to aircraft designed for this purpose, most powered aircraft are capable of gliding without engine power. As with sustained flight, gliding generally requires the application of an airfoil, such as the wings on aircraft or birds, or the Patagium, gliding membrane of a gliding possum. However, gliding can be achieved with a flat (Camber (aerodynamics), uncambered) wing, as with a simple paper plane, or even with card-throwing. However, some aircraft with lifting body, lifting bod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Syndactyly
Syndactyly is a condition wherein two or more digits are fused together. It occurs normally in some mammals, but is an unusual condition in humans. The term is . Classification Syndactyly can be simple or complex. * In simple syndactyly, adjacent fingers or toes are joined by soft tissue. * In complex syndactyly, the bones of adjacent digits are fused. The kangaroo exhibits complex syndactyly. Syndactyly can be complete or incomplete. * In complete syndactyly, the skin is joined all the way to the tip of the involved digits. * In incomplete syndactyly, the skin is only joined part of the distance to the tip of the involved digits. Complex syndactyly occurs as part of a syndrome (such as Apert syndrome) and typically involves more digits than simple syndactyly. Fenestrated syndactyly, also known as acrosyndactyly or terminal syndactyly, means the skin is joined for most of the digit but in a proximal area there are gaps in the syndactyly with normal skin. This type of synda ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Krefft's Glider
Krefft's glider (''Petaurus notatus'') is a species of Arboreal locomotion, arboreal nocturnal gliding possum, a type of small marsupial. It is native to most of eastern mainland Australia and has been introduced to Tasmania. Populations of ''Petaurus'' from New Guinea and Indonesia previously classified under ''P. breviceps'' are also tentatively classified under ''P. notatus'' by the American Society of Mammalogists, but likely represent a complex of distinct species. As most captive gliders referred to as "Sugar glider, sugar gliders" in at least the United States are thought to originate from West Papua (province), West Papua, this likely makes them Krefft's gliders, at least tentatively. Taxonomy It is closely allied with the sugar glider (''P. breviceps''), with which it was long taxonomically confused. A 2020 study partially clarified the taxonomy of the sugar glider and split it into three species: the savanna glider (''P. ariel''), the sugar glider (''P. breviceps sensu ...

Squirrel Glider
The squirrel glider (''Petaurus norfolcensis'') is a nocturnal gliding possum. The squirrel glider is one of the wrist-winged gliders of the genus '' Petaurus''. Habitat This species' home range extends from Bordertown near the South Australian/Victorian Border through south-eastern Australia to northern Queensland. This species was thought to be extinct in South Australia since 1939 until a genetic test confirmed their inhabitance in this area. The squirrel glider lives in south-eastern Australia in the dry sclerophyll forest and woodlands. In Queensland, however, they occupy a wetter eucalypt forest. The glider will make a den in the hollow tree and line it with leaves. Here it will sleep and usually lives in groups of one male, 2 females, and offspring. Appearance Like most of the wrist-winged gliders, the squirrel glider is endemic to Australia. It is about twice the size of the related sugar glider (''P. breviceps''). Its body is 18–23 cm long and its tail meas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sugar Glider
The sugar glider (''Petaurus breviceps'') 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. The sugar glider is characterised by its pair of gliding membranes, known as patagia, which extend from its forelegs to its hindlegs. Gliding serves as an efficient means of reaching food and evading predators. The animal is covered in soft, pale grey to light brown fur which is countershaded, being lighter in colour on its underside. The sugar glider, as strictly defined in a recent analysis, is only native to a small portion of southeaste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Savanna Glider
The savanna glider (''Petaurus ariel'') is a species of arboreal gliding possum in the genus '' Petaurus''. Taxonomy It was long considered a subspecies of the sugar glider (''P. breviceps''), but a 2020 study split ''P. breviceps'' into 3 distinct species, with ''P. ariel'' being found to represent one of these distinct species. Names The Bininj of western Arnhem Land, Australia call this animal lambalk in their Kunwinjku language. Description The species somewhat resembles a small squirrel glider (''P. norfolcensis'') with a pointed nose. It displays substantial body size variation throughout its range; in the northern, more coastal portions, it is small enough to be considered the smallest of all Australian ''Petaurus''. However, in the arid inland parts of its range to the south, it can grow to be twice as large. Distribution The species lives in the wooded savannas of northern Australia. It ranges from northwestern Queensland west through the Northern Territory ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
