Biswamoyopterus
''Biswamoyopterus'' is a genus of rodent in the family Sciuridae. It contains three known species of very large flying squirrels, with '' 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 described relatively recently. 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'' * Laotian giant flying squirrel The Laotian giant flying squirrel (''Biswamoyopterus laoensis'') is an arboreal, flying squirrel endemic to Laos. It was the second described member in the genus ''Biswamoyopterus'', after being first collected in September 2012 by scientists res ... ''Biswamoyo ...

Biswamoyopterus Laoensis
The Laotian giant flying squirrel (''Biswamoyopterus laoensis'') is an arboreal, flying squirrel endemic to Laos. It was the second described member in the genus ''Biswamoyopterus'', after being first collected in September 2012 by scientists researching the animal corpses in the illegal Thongnami bushmeat market, Ban Thongnami, Pakkading District, Bolikhamxai Province.

Laotian Giant Flying Squirrel
The Laotian giant flying squirrel (''Biswamoyopterus laoensis'') is an arboreal, flying squirrel endemic to Laos.

Description ''Biswamoyopterus laoensis'' has reddish, grizzled fur Fur is a thick growth of hair that covers the skin of mammals.

Biswamoyopterus Biswasi
The Namdapha flying squirrel (''Biswamoyopterus biswasi'') is an arboreal, nocturnal flying squirrel endemic to Arunachal Pradesh in northeast India, where it is known from a single specimen collected in Namdapha National Park in 1981. No population estimate is available for ''B. biswasi'', but the known habitat is tall ''Mesua ferrea'' jungles, often on hill slopes in the catchment area of Dihing River (particularly on the western slope of Patkai range) in northeastern India. It was the sole member in the genus ''Biswamoyopterus'' until the description of the Laotian giant flying squirrel (''Biswamoyopterus laoensis'') in 2013. In 2018, Quan Li from the Kunming Institute of Zoology at the Chinese Academy of Sciences discovered a new squirrel in the same genus while studying specimens in their collection, called the Mount Gaoligong flying squirrel (''Biswamoyopterus gaoligongensis''), based on the region it was discovered in.

Biswamoyopterus Gaoligongensis
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.

Flying Squirrel
Flying squirrels (scientifically known as Pteromyini or Petauristini) are a tribe of 50 species of squirrels in the family 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 glide from one tree to another with the aid of a patagium, a furred parachute-like 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 monophyletic and originated some 18–20 million years ago. The genus Paracitellus is the earliest lineage to the flying squirrel dating back to the late Oligocene era. Most are nocturnal ...

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 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 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 species were recognised in ''Mammal Species of the Wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rodent
Rodents (from Latin , 'to gnaw') are mammals of the order Rodentia (), which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for New Zealand, Antarctica, and several oceanic islands, though they have subsequently been introduced to most of these land masses by human activity. Rodents are extremely diverse in their ecology and lifestyles and can be found in almost every terrestrial habitat, including human-made environments. Species can be arboreal, fossorial (burrowing), saltatorial/richochetal (leaping on their hind legs), or semiaquatic. However, all rodents share several morphological features, including having only a single upper and lower pair of ever-growing incisors. Well-known rodents include mice, rats, squirrels, prairie dogs, porcupines, beavers, guinea pigs, and hamsters. Rabbits, hares, and pikas, whose i ...

Sciuridae
Squirrels are members of the family Sciuridae, a family that includes small or medium-size 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 to the 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 word , which was taken from the Ancient Greek word (; from ) 'shadow-tailed', referring to the long bushy tail which many of its members have. The native Old English word for the squirrel, , survived only into Middle English (as ) before being replaced. The Old English word is of Common Germanic origin, cognat ...
