Amyda
''Amyda'' is a genus of softshell turtles in the family Trionychidae. It contains two extant species: * ''Amyda cartilaginea'' - Asiatic softshell turtle * ''Amyda ornata'' - Southeast Asian softshell turtle Both species were formerly considered subspecies of a single species, ''Amyda cartilaginea'', but phylogenetic evidence supports both being distinct from one another. An undescribed species is also known from Borneo. The fossil taxon '' 'Amyda'' ' ''gregaria'' from the Eocene of Inner Mongolia has been tentatively placed in the genus '' Trionyx''. When it comes to the eating habits of Amyda, considering its multiple species, they are known for being opportunist omnivores An omnivore () is an animal that regularly consumes significant quantities of both plant and animal matter. Obtaining energy and nutrients from plant and animal matter, omnivores digest carbohydrates, protein, fat, and fiber, and metabolize t .... Their diet consists mainly of plants and fish. Re ...

Asiatic Softshell Turtle
The Asiatic softshell turtle or black-rayed softshell turtle (''Amyda cartilaginea'') is a species of softshell turtle in the Trionychidae family. Despite its name, it is not the only softshell turtle in Asia (most trionychines are Asian). Taxonomy Formerly considered the only extant species within '' Amyda'', a 2014 study found deep genetic divergence within this species and supported splitting it into three distinct species: ''A. cartilaginea sensu stricto'', ''A. ornata'' (the Southeast Asian softshell turtle), and an undescribed species from Borneo. Both ''Amyda cartilaginea'' and ''Amyda ornata'' branch into further subspecies, while ''Amyda'' (unnamed) is a terminal clade in itself. ''Amyda cartilagineas subspecies are: Amyda cartilaginea cartilaginea (''located in E. Sunde, E. Borneo, Java, and Sulawesi'') and Amyda cartilaginea maculosa (''found in Sumatra and West Borneo'').'' As for any marked different physical characteristics, ''Amyda cartilaginea cartilaginea' ...

Amyda Ornata
The Southeast Asian softshell turtle (''Amyda ornata'') is a species of softshell turtle in the family Trionychidae. Taxonomy It was formerly considered a subspecies of the Asiatic softshell turtle (''A. cartilaginea''), which is now thought to be restricted to the Malay Peninsula and the Malay Archipelago. A 2014 phylogenetic study found both to be distinct species from one another. The Reptile Database and Turtle Taxonomy Working Group also consider both to be distinct species. There are two subspecies: * ''A. o. ornata'' (Gray, 1861) ''–'' Thailand, Laos, Vietnam, Cambodia * ''A. o. phayrei'' (Theobald, 1868) – India, Bangladesh, Myanmar, Thailand An undescribed subspecies is also known from Bangladesh, though the TTWG classifies it within ''A. o. phayrei''. Distribution The species is found throughout much of Mainland Southeast Asia, and ranges from northwestern India south to southern Myanmar and east to Vietnam.

Softshell Turtle
Trionychidae is a family of turtles, commonly known as softshell turtles or simply softshells. The family was described by Leopold Fitzinger in 1826. Softshells include some of the world's largest freshwater turtles, though many can adapt to living in highly brackish waters. Members of this family occur in Africa, Asia, and North America, with extinct species known from Australia. Most species have traditionally been included in the genus '' Trionyx'', but the vast majority have since been moved to other genera. Among these are the North American '' Apalone'' softshells that were placed in ''Trionyx'' until 1987. Characteristics Turtles of the family Trionychidae are called "softshell" because their carapaces lack horny scutes (scales), though the spiny softshell, '' Apalone spinifera'', does have some scale-like projections, to which its common name refers. The carapace is leathery and pliable, particularly at the sides. The central part of the carapace has a layer of solid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inner Mongolia
Inner Mongolia, officially the Inner Mongolia Autonomous Region, is an Autonomous regions of China, autonomous region of China. Its border includes two-thirds of the length of China's China–Mongolia border, border with the country of Mongolia. Inner Mongolia also accounts for a small section of China's China–Russia border, border with Russia (Zabaykalsky Krai). Its capital is Hohhot; other major cities include Baotou, Chifeng, Tongliao, and Ordos City, Ordos. The autonomous region was established in 1947, incorporating the areas of the former Republic of China (1912–1949), Republic of China provinces of Suiyuan, Chahar Province, Chahar, Rehe Province, Rehe, Liaobei, and Xing'an Province, Xing'an, along with the northern parts of Gansu and Ningxia. Its area makes it the List of Chinese administrative divisions by area, third largest Chinese administrative subdivision, constituting approximately and 12% of China's total land area.

Turtle Genera
Turtles are reptiles of the order (biology), order Testudines, characterized by a special turtle shell, shell developed mainly from their ribs. Modern turtles are divided into two major groups, the Pleurodira (side necked turtles) and Cryptodira (hidden necked turtles), which differ in the way the head retracts. There are 360 living and recently extinct species of turtles, including land-dwelling tortoises and freshwater terrapins. They are found on most continents, some islands and, in the case of sea turtles, much of the ocean. Like other Amniote, amniotes (reptiles, birds, and mammals) they breathe air and do not lay eggs underwater, although many species live in or around water. Turtle shells are made mostly of bone; the upper part is the domed Turtle shell#Carapace, carapace, while the underside is the flatter plastron or belly-plate. Its outer surface is covered in scale (anatomy), scales made of keratin, the material of hair, horns, and claws. The carapace bones deve ...

Omnivore
An omnivore () is an animal that regularly consumes significant quantities of both plant and animal matter. Obtaining energy and nutrients from plant and animal matter, omnivores digest carbohydrates, protein, fat, and fiber, and metabolize the nutrients and energy of the sources absorbed. Often, they have the ability to incorporate food sources such as algae, fungi, and bacteria into their diet. Omnivores come from diverse backgrounds that often independently evolved sophisticated consumption capabilities. For instance, dogs evolved from primarily carnivorous organisms (Carnivora) while pigs evolved from primarily herbivorous organisms (Artiodactyla). Despite this, physical characteristics such as tooth morphology may be reliable indicators of diet in mammals, with such morphological adaptation having been observed in bears. The variety of different animals that are classified as omnivores can be placed into further sub-categories depending on their feeding behaviors. Frug ...

Trionyx
''Trionyx'' is a genus of softshell turtles belonging to the family Trionychidae. In the past many species in the family were classified in this genus, but today '' T. triunguis'', the African or Nile softshell turtle, is the only extant softshell still classified as ''Trionyx''. The other species still assigned to this genus are only known from fossils. ''T. triunguis'' is a relatively large, aquatic piscivore. Species The list of species follows a 2017 review of the Trionychidae by Georgios L. Georgalis and Walter G. Joyce. * '' Trionyx triunguis'' ( Forsskål, 1775) – African or Nile softshell turtle * † '' Trionyx pliocenicus'' Fucini, 1912 – Pliocene of Tuscany (Italy) * † '' Trionyx vindobonensis'' (Peters, 1855) – Miocene of Vienna (Austria) The following species are considered valid trionychid taxa, but with uncertain phylogenetic relationships. They are only referred to ''Trionyx'' provisionally due to its historic status as a wastebasket taxon Wasteba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Borneo
Borneo () is the List of islands by area, third-largest island in the world, with an area of , and population of 23,053,723 (2020 national censuses). Situated at the geographic centre of Maritime Southeast Asia, it is one of the Greater Sunda Islands, located north of Java Island, Java, west of Sulawesi, and east of Sumatra. The island is crossed by the equator, which divides it roughly in half. The list of divided islands, island is politically divided among three states. The sovereign state of Brunei in the north makes up 1% of the territory. Approximately 73% of Borneo is Indonesian territory, and in the north, the East Malaysian states of Sabah and Sarawak make up about 26% of the island. The Malaysian federal territory of Labuan is situated on a small island just off the coast of Borneo. Etymology When the sixteenth-century Portuguese explorer Jorge de Menezes made contact with the indigenous people of Borneo, they referred to their island as ''Pulu K'lemantang'', which ...
