Cyclanorbis Elegans
The Nubian flapshell turtle or Nubian soft-shelled turtle (''Cyclanorbis elegans'') is one of two species of softshell turtle in the genus ''Cyclanorbis'' of the Trionychidae family. It is thought to have ranged from West Africa east through Central Africa to South Sudan, although it has been extirpated from the vast majority of its range. Distribution It has historically been found in a wide range spanning Benin, Central African Republic, Chad, Ethiopia, Ghana, Nigeria, Sudan, and Togo. However, it has been very rarely recorded during the last 50 years and there is little hope that the species is extant in West Africa. In 2017, a remnant population was found in the White Nile wetlands in South Sudan by Prof. Luca Luiselli and his team; this discovery was publicized in a 2019 paper. In 2021, another population was found along the White Nile wetlands in northern Uganda, near the border with South Sudan; the species was not previously recorded in this area. Descrip ...

John Edward Gray
John Edward Gray, FRS (12 February 1800 – 7 March 1875) was a British zoologist. He was the elder brother of zoologist George Robert Gray and son of the pharmacologist and botanist Samuel Frederick Gray (1766–1828). The same is used for a zoological name. Gray was keeper of zoology at the British Museum in London from 1840 until Christmas 1874, before the natural history holdings were split off to the Natural History Museum. He published several catalogues of the museum collections that included comprehensive discussions of animal groups and descriptions of new species. He improved the zoological collections to make them amongst the best in the world. Biography Gray was born in Walsall, but his family soon moved to London, where Gray studied medicine. He assisted his father in writing ''The Natural Arrangement of British Plants'' (1821). After being blackballed by the Linnean Society of London, Gray shifted his interest from botany to zoology. He began his zoologica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White Nile
The White Nile ( ar, النيل الأبيض ') is a river in Africa, one of the two main tributaries of the Nile, the other being the Blue Nile. The name comes from the clay sediment carried in the water that changes the water to a pale color. In the strict meaning, "White Nile" refers to the river formed at Lake No, at the confluence of the Bahr al Jabal and Bahr el Ghazal Rivers. In the wider sense, "White Nile" refers to all the stretches of river draining from Lake Victoria through to the merger with the Blue Nile; the "Victoria Nile" from Lake Victoria via Lake Kyoga to Lake Albert, then the "Albert Nile" to the South Sudan border, and then the "Mountain Nile" or "Bahr-al-Jabal" down to Lake No. "White Nile" may sometimes include the headwaters of Lake Victoria, the most remote of which being from the Blue Nile. The 19th-century search by Europeans for the source of the Nile was mainly focused on the White Nile, which disappeared into the depths of what was then known ...

Taxa Named By John Edward Gray
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reptiles Of West Africa
Reptiles, as most commonly defined are the animals in the class Reptilia ( ), a paraphyletic grouping comprising all sauropsids except birds. Living reptiles comprise turtles, crocodilians, squamates (lizards and snakes) and rhynchocephalians (tuatara). As of March 2022, the Reptile Database includes about 11,700 species. In the traditional Linnaean classification system, birds are considered a separate class to reptiles. However, crocodilians are more closely related to birds than they are to other living reptiles, and so modern cladistic classification systems include birds within Reptilia, redefining the term as a clade. Other cladistic definitions abandon the term reptile altogether in favor of the clade Sauropsida, which refers to all amniotes more closely related to modern reptiles than to mammals. The study of the traditional reptile orders, historically combined with that of modern amphibians, is called herpetology. The earliest known proto-reptiles originated around 31 ...

Vertebrates Of Sudan
Vertebrates () comprise all animal taxa within the subphylum Vertebrata () (chordates with backbones), including all mammals, birds, reptiles, amphibians, and fish. Vertebrates represent the overwhelming majority of the phylum Chordata, with currently about 69,963 species described. Vertebrates comprise such groups as the following: * jawless fish, which include hagfish and lampreys * jawed vertebrates, which include: ** cartilaginous fish (sharks, rays, and ratfish) ** bony vertebrates, which include: *** ray-fins (the majority of living bony fish) *** lobe-fins, which include: **** coelacanths and lungfish **** tetrapods (limbed vertebrates) Extant vertebrates range in size from the frog species ''Paedophryne amauensis'', at as little as , to the blue whale, at up to . Vertebrates make up less than five percent of all described animal species; the rest are invertebrates, which lack vertebral columns. The vertebrates traditionally include the hagfish, which do not have pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bari People
The Bari are a tribe of Karo, Nilotic people inhabiting South Sudan. The Bari speak the Bari language as a mother tongue, which belongs to the Nilotic family. Overview The Bari of the Nile are sedentary agro-pastoralist. They exploit the savanna lands along the river Nile, and up to 40 miles east and west of the Nile. Their economy is based on subsistence mixed farming; their domestic livestock (small and large) are mainly raised for supplementing food, but mostly as a socio-economic and financial investment. Notably, livestock are exchanged as gifts in marriages, and other social functions or sacrificed in celebrations, and funerals; and whenever the need arises they are sold for cash. The Bari used to own large herds of cattle but due to being victims of destructive slave raids which caused the spread of the tsetse fly, they have far less cattle than in the past. The Bari are consistently under pressure: now from modern urbanization annexing their green lands and infusi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
