Biswamoyopterus Gaoligongensis
''Biswamoyopterus'' is a genus of rodent in the family Sciuridae. It contains three known species of very large flying squirrels, with ''Laotian giant flying squirrel, B. laoensis'' being among the longest of all squirrels. They are distributed in forests in northeast India, southwest China and Laos. Despite their size, species in this genus tend to be very elusive; due to this, all of them have been Species description, described relatively recently. In fact 2 out of the 3 species are only known from a single specimen. Additionally, they are easily confused with certain ''Petaurista'' giant flying squirrels that are more common and overlap in range with the rare ''Biswamoyopterus''. Species There are currently three known species in this genus: * Namdapha flying squirrel ''Biswamoyopterus biswasi'' * Mount Gaoligong flying squirrel ''Biswamoyopterus gaoligongensis'' * Laotian giant flying squirrel ''Biswamoyopterus laoensis'' Recent studies have suggested that the three known ...

Zoological Specimen
A zoological specimen is an animal or part of an animal preserved for scientific use. Various uses are: to verify the identity of a (species), to allow study, increase public knowledge of zoology. Zoological specimens are extremely diverse. Examples are bird and mammal study skins, mounted specimens, skeletal material, casts, pinned insects, dried material, animals preserved in liquid preservatives, and microscope slides. Natural history museums are repositories of zoological specimens Study skins Bird and mammal specimens are conserved as dry study skins, a form of taxidermy. The skin is removed from the animal's carcass, treated with absorbents, and filled with cotton or polyester batting (In the past plant fibres or sawdust were used). Bird specimens have a long, thin, wooden dowel wrapped in batting at their center. The dowel is often intentionally longer than the bird's body and exits at the animal's vent. This exposed dowel provides a place to handle the bird without distu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
India
India, officially the Republic of India, is a country in South Asia. It is the List of countries and dependencies by area, seventh-largest country by area; the List of countries by population (United Nations), most populous country since 2023; and, since its independence in 1947, the world's most populous democracy.

Mount Gaoligong Flying Squirrel
The Mount Gaoligong flying squirrel (''Biswamoyopterus gaoligongensis'') is a species of large, arboreal flying squirrel endemic to highland forests in southwestern China. It is the third known member of the highly elusive genus ''Biswamoyopterus''. It was described from two specimens discovered in 2017 and 2018, in the vicinity of Mount Gaoligong in the western Yunnan Province. These specimens were distinct from the other two species in the genus in both coloration and skull shape, indicating that they belonged to a distinct species. This species has also been photographed at two different localities at the eastern and western slopes of Mount Gaoligong. A single specimen of the Mount Gaoligong flying squirrel had a head-and-body length of , a tail length of and a weight of . Despite being distantly related, the Mount Gaoligong flying squirrel is easily confused with the more common Yunnan giant flying squirrel; they occur together at Mount Gaoligong. Its natural habitat is eve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Namdapha Flying Squirrel
The Namdapha flying squirrel (''Biswamoyopterus biswasi'') is a flying squirrel endemic to Arunachal Pradesh in northeast India, where it is known from a single zoological specimen collected in Namdapha National Park in 1981. Description The Namdapha flying squirrel has reddish, grizzled fur with white above and a pale grey crown; its patagium is orangish and its underparts are white. Its cheek teeth are simple, and its incisors are unpigmented. Septae are multiple in auditory bullae and sometimes honeycomb-shaped with 10 to 12 cells in it. It measures from head-to- vent and has a long tail. The hindfoot is , and the ear is long. Taxonomy The Namdapha flying squirrel first described in 1981, based on a single zoological specimen collected in Namdapha National Park.

Petaurista
''Petaurista'' is a genus of rodent in the family Sciuridae. They are large to very large flying squirrels found in forests and other wooded habitats in southern and eastern Asia. Like other flying squirrels, they are mostly nocturnal and able to Flying and gliding animals, glide (not actually fly like a bat) long distances between trees by spreading out their patagium, skin between their limbs. They feed primarily on plant material, but will also take small animals such as insects. Taxonomy The species level Taxonomy (biology), taxonomy is very complex and not fully resolved. In 2005, ''Mammal Species of the World'' recognised eight species, but later studies have found that some of these were highly polyphyletic, and recent authorities have often recognised some of the most divergent "subspecies" as valid species. Additionally, three new species were described from northeastern India in 2007–2013, although their validity needs to be confirmed. Living species Eight specie ...

Species Description
A species description is a formal scientific description of a newly encountered species, typically articulated through a scientific publication. Its purpose is to provide a clear description of a new species of organism and explain how it differs from species that have been previously described or related species. For a species to be considered valid, a species description must follow established guidelines and naming conventions dictated by relevant nomenclature codes. These include the International Code of Zoological Nomenclature (ICZN) for animals, the International Code of Nomenclature for algae, fungi, and plants (ICN) for plants, and the International Committee on Taxonomy of Viruses (ICTV) for viruses. A species description often includes photographs or other illustrations of type material and information regarding where this material is deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flying Squirrel
Flying squirrels (scientifically known as Pteromyini or Petauristini) are a tribe (biology), tribe of 50 species of squirrels in the family (biology), family Squirrel, Sciuridae. Despite their name, they are not in fact capable of full flight in the same way as birds or bats, but they are able to gliding flight, glide from one tree to another with the aid of a patagium, a furred skin membrane that stretches from wrist to ankle. Their long tails also provide stability as they glide. Anatomically they are very similar to other squirrels with a number of adaptations to suit their lifestyle; their limb bones are longer and their hand bones, foot bones, and distal vertebrae are shorter. Flying squirrels are able to steer and exert control over their glide path with their limbs and tail. Molecular studies have shown that flying squirrels are Monophyly, monophyletic (having a common ancestor with no non-flying descendants) and originated some 18–20 million years ago. The genus ''Par ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sciuridae
Squirrels are members of the family Sciuridae (), a family that includes small or medium-sized rodents. The squirrel family includes tree squirrels, ground squirrels (including chipmunks and prairie dogs, among others), and flying squirrels. Squirrels are indigenous to the Americas, Eurasia, and Africa, and were introduced by humans to Australia. The earliest known fossilized squirrels date from the Eocene epoch, and among other living rodent families, the squirrels are most closely related to the mountain beaver and dormice. Etymology The word ''squirrel'', first attested in 1327, comes from the Anglo-Norman which is from the Old French , the reflex of a Latin language">Latin word , which was taken from the Ancient Greek word (; from ) 'shadow-tailed', referring to the long bushy tail which many of its members have. ''Sciurus'' is also the name of one of its genuses. The native Old English language, Old English word for the squirrel, , only survived into Middle Eng ...
