Aubry's Flapshell Turtle
Aubry's flapshell turtle (''Cycloderma aubryi'') is a species of softshell turtle in the family Trionychidae. The species is endemic to Central Africa. Etymology The specific name, ''aubryi'', is in honor of Charles Eugène Aubry-Lecomte (1821–1879), who was a French civil servant and an amateur naturalist. Geographic range ''C. aubryi'' is found in the Democratic Republic of Congo, Gabon, the Cabinda Province of Angola and likely in the Central African Republic. Habitat The preferred natural habitats of ''C. aubryi'' are forest and freshwater wetlands, at altitudes up to . Diet Adults of ''C. aubryi'' prey upon crabs, crayfish, and fish. Juveniles may also eat insects.

Zambezi Flapshell Turtle
The Zambezi flapshell turtle (''Cycloderma frenatum'') is a species of softshell turtle in the family Trionychidae). Within its family, ''C. frenatum'' belongs to the smaller, and exclusively Old World, subfamily Cyclanorbinae. Geographic range ''C. frenatum'' is found in southeastern Africa, in the countries of Malawi, Mozambique, Tanzania, Zambia, Zanzibar, and Zimbabwe,"''Cycloderma frenatum'' ". The Reptile Database. www.reptile-database.org. and mainly in the Zambezi basin. Conservation status ''C. frenatum'' is becoming rare due to habitat loss Habitat destruction (also termed habitat loss or habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved elsewhere, or are dead, leading to a decrease .... References Further reading * Peters W (1854).

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] |
Cyclanorbinae
Cyclanorbinae, also known commonly as the flapshell turtles, is a subfamily of softshell turtles in the family Trionychidae. The subfamily is native to Africa and Asia. Taxonomy Morphological evidence supports Cyclanorbinae being the sister group to the Plastomeninae, an extinct subfamily of softshell turtles that inhabited North America from the Cretaceous to the Eocene. Genera The subfamily Cyclanorbinae contains the following three extant genera.Turtle Taxonomy Working Group (Rhodin, Anders G.J.; Parham, James F.; van Dijk, Peter Paul; Iverson, John B.)

Miocene
The Miocene ( ) is the first epoch (geology), geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene followed the Oligocene and preceded the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by distinct global events but by regionally defined transitions from the warmer Oligocene to the cooler Pliocene Epoch. During the Early Miocene, Afro-Arabia collided with Eurasia, severing the connection between the Mediterranean and Indian Oceans, and allowing the interchange of fauna between Eurasia and Africa, including the dispersal of proboscideans and Ape, hominoids into Eurasia. During the late Miocene, the conn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (often shortened to just "binomial"), a binomen, name, or a scientific name; more informally, it is also called a Latin name. In the International Code of Zoological Nomenclature (ICZN), the system is also called nomenclature, with an "n" before the "al" in "binominal", which is a typographic error, meaning "two-name naming system". The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Hom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nota Bene
( ; plural: ) is the Latin language, Latin phrase meaning ''note well''. In manuscripts, ''nota bene'' is abbreviated in upper-case as NB and N.B., and in lower-case as n.b. and nb; the editorial usages of ''nota bene'' and ''notate bene'' first appeared in the English writing style, English style of writing around the year 1711. In Modern English, since the 14th century, the editorial usage of ''NB'' is common to the legal writing, legal style of writing of documents to direct the reader's attention to a thematically relevant aspect of the subject that qualifies the matter being litigated, whereas in academic writing, the editorial abbreviation ''n.b.'' is a casual synonym for ''footnote''. In medieval manuscripts, the editorial marks used to draw the reader's attention to a supporting text also are called marks; however, the catalogue of medieval editorial marks does not include the NB abbreviation. The medieval equivalents to the n.b.-mark are anagrams derived from the f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
