Aphanius Apodus
''Aphanius apodus'' is a species of fish in the family Cyprinodontidae. This species is endemic to springs and streams in the Atlas mountains of Algeria, between Batna and Constantine. ''A. apodus'' was described as ''Lebias apodus'' in 1853 by Paul Gervais with the type locality given as the Springs of Tell, south of Constantine.

It is the only ''Aphanius'' species which lacks pectoral fins. This species can grow up to the average length of about 45 millimeters or about two inches. The aphanius apodus has the diet of eating small aquatic crustaceans, worms, insect larvae, zooplankton, algae, and occasionally plant material is eaten. If bred for the aquarium, this species can accept dried ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paul Gervais
Paul Gervais full name François Louis Paul Gervais (26 September 1816 – 10 February 1879) was a French palaeontologist and entomologist. Biography Gervais was born in Paris, where he obtained the diplomas of doctor of science and of medicine, and in 1835 he began palaeontological research as assistant in the laboratory of comparative anatomy at the ''Muséum national d'Histoire naturelle''. In 1841 he obtained the chair of zoology and comparative anatomy at the Faculty of Sciences in Montpellier, of which he was in 1856 appointed dean. In 1848–1852 appeared his important work ''Zoologie et paléontologie françaises'', supplementary to the palaeontological publications of Georges Cuvier and Henri Marie Ducrotay de Blainville; of this a second and greatly improved edition was issued in 1859. In 1865 he accepted the professorship of zoology at the Sorbonne, vacant through the death of Louis Pierre Gratiolet; this post he left in 1868 for the chair of comparative anatomy at the ...

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Fauna Of Algeria
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aphanius
''Aphanius'' is a genus of pupfishes. Unlike other members of the family which are from the Americas, ''Aphanius'' species are native to northern Africa, southwestern Asia (as far east as India) and southern Europe. Several species in the genus have very small distributions and are seriously threatened. Fossil record Fossils of ''Aphanius'' are found in strata of the Pleistocene of Italy (age range: from 11.608 to 5.332 million years ago.). Species The 39 recognized species in this genus are: * ''Aphanius almiriensis'' Kottelat, Barbieri & Stoumboudi, 2007 * ''Aphanius anatoliae'' Leidenfrost, 1912 (Lake Tuz toothcarp) * ''Aphanius apodus'' Gervais, 1853 * ''Aphanius arakensis'' Teimori, Esmaeili, Gholami, Zarei & Reichenbacher ( de), 2012 Teimori, A., Esmaeili, H.R., Gholami, Z., Zarei, N. & Reichenbacher, B.

Fish Of North Africa
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Most fis ...

Type Locality (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost a ...

Batna, Algeria
Batna ( ar, باتنة, Latn, ar, Bātnah) is the main city and commune of Batna Province, Algeria. With a population of 290,645 (2008 census) it is the fifth largest city in Algeria. It is also one of the principal cities of the Chaoui area and is considered the capital of Aurès. History The first solid foundations (a military encampment) of the city were erected by a French garrison in 1844, with a strategic mission to create a permanently guarded access point for the main Sahara road. Batna's geographical location offers a natural break through the Atlas Mountains. The Romans did not detect this passage in their early invasion phase. The ancient cities of Timgad and Lambese, built around the first century CE, are living examples of the importance that the Romans gave to commercial control over the region. Signature and proclamation of the Algerian revolution Batna The inhabitants of the city revolted against the French authorities at the beginning of colonization. Th ...

Atlas Mountains
The Atlas Mountains are a mountain range in the Maghreb in North Africa. It separates the Sahara Desert from the Mediterranean Sea and the Atlantic Ocean; the name "Atlantic" is derived from the mountain range. It stretches around through Morocco, Algeria and Tunisia. The range's highest peak is Toubkal, which is in central Morocco, with an elevation of . The Atlas mountains are primarily inhabited by Berbers, Berber populations. The terms for 'mountain' are ''Adrar'' and ''adras'' in some Berber languages, and these terms are believed to be cognates of the Toponymy, toponym ''Atlas''. The mountains are also home to a number of animals and plants which are mostly found within Africa but some of which can be found in Europe. Many of these species are endangered and a few are already extinct. The weather is cooling but has sunny summers, and the average temperature there is 25°C.Atlas Mountains are a mountain range in the Maghreb in North Africa. It separates the Sahara Desert fro ...
