Tristramella Magdelainae
''Tristramella magdelainae'' is an extinct species of cichlid fish. It was endemic to the vicinity of Damascus in Syria. It was last recorded in the 1950s, has not been recorded since and is presumed extinct. Drought, pollution and water extraction may have destroyed its habitat. This taxon is considered to be a subspecies of '' T. simonis'' in FishBase and considered a synonym of ''T. simonis'' by Catalog of Fishes,http://research.calacademy.org/redirect?url=http://researcharchive.calacademy.org/research/ichthyology/catalog/fishcatget.asp&tbl=species&spid=38597 a view that FishBase now (2018) concurs with.

Louis Charles Émile Lortet
Louis Charles Émile Lortet (22 August 1836 – 26 December 1909) was a French physician, botanist, zoologist and Egyptologist who was a native of Oullins. He earned his medical doctorate in 1861, and his degree in natural sciences in 1867. He served as premier doyen at the Faculty of Medicine of Lyon from 1877 until 1906. Also, from 1868 to 1909, he was director of the natural history museum in Lyon. Lortet is remembered for his scientific and zoological expeditions to the Middle East (Syria, Lebanon and Egypt). He performed studies of mummified animals from the New Kingdom of ancient Egypt, and in 1880 took part in an excavation of a Phoenician necropolis. Lortet was a member of numerous scientific societies, such as the ''Société de géographie de Lyon'', being a founding member in 1858. Species with the epithet of ''lorteti'' are named in his honor; an example being the pufferfish species ''Carinotetraodon lorteti''. Family His Grandmother Clémence Lortet (17 September ...

Endemic Fauna Of Syria
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 sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Of Syria
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 ...

Cichlid Fish Of Asia
Cichlids are fish from the family Cichlidae in the order Cichliformes. Cichlids were traditionally classed in a suborder, the Labroidei, along with the wrasses ( Labridae), in the order Perciformes, but molecular studies have contradicted this grouping. The closest living relative of cichlids is probably the convict blenny, and both families are classified in the 5th edition of '' Fishes of the World'' as the two families in the Cichliformes, part of the subseries Ovalentaria. This family is both large and diverse. At least 1,650 species have been scientifically described, making it one of the largest vertebrate families. New species are discovered annually, and many species remain undescribed. The actual number of species is therefore unknown, with estimates varying between 2,000 and 3,000. Many cichlids, particularly tilapia, are important food fishes, while others, such as the ''Cichla'' species, are valued game fish. The family also includes many popular freshwater aquar ...

Tristramella
''Tristramella'' is a genus of oreochromines, freshwater fishes in the cichlid family. The members of this genus prefer standing waters and their native range is restricted to the Jordan River system, including Lake Tiberias (Kinneret), in Israel and Syria, with introduced populations in a few other places in Syria. Its members are among the few cichlids native to Western Asia, the others being ''Astatotilapia flaviijosephi'', '' Coptodon zillii'', ''Iranocichla'', ''Oreochromis aureus'', '' O. niloticus'' and ''Sarotherodon galilaeus''. Locally, ''T. simonis'' remains common and an important part of fisheries, but overall it has declined and it is considered threatened. In contrast, ''T. sacra'' has been extinct since 1989–90, possibly due to the disappearance of its breeding habitat, marshes in Lake Tiberias. ''Tristramella'' reach up to in total length. Overall they resemble typical tilapias and the ''Tristramella'' species differ from each other mainly in details of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Standard Length
Fish measurement is the measuring of individual fish and various parts of their anatomies. These data are used in many areas of ichthyology, including taxonomy and fisheries biology. Overall length * Standard length (SL) is the length of a fish measured from the tip of the snout to the posterior end of the last vertebra or to the posterior end of the midlateral portion of the hypural plate. Simply put, this measurement excludes the length of the caudal (tail) fin. * Total length (TL) is the length of a fish measured from the tip of the snout to the tip of the longer lobe of the caudal fin, usually measured with the lobes compressed along the midline. It is a straight-line measure, not measured over the curve of the body. Standard length measurements are used with Teleostei (most bony fish), while total length measurements are used with Myxini (hagfish), Petromyzontiformes (lampreys), and (usually) Elasmobranchii (sharks and rays), as well as some other fishes.

Catalog Of Fishes
Catalog of Fishes is a comprehensive on-line database and reference work on the scientific names of fish species and genera. It is global in its scope and is hosted by the California Academy of Sciences. It has been compiled and is continuously updated by the curator emeritus of the CAS fish collection, William N. Eschmeyer. The taxonomy maintained by the Catalog of Fishes is considered authoritative and it is used as a baseline reference for instance by the broader global fish database FishBase, which involves cross-references to the Catalog's information for all accepted taxa. , the searchable catalogue contains entries for about 58,300 fish species names, about 33,400 of which are currently accepted (valid), and for some 10,600 genera (5,100 valid).

Tristramella Simonis
''Tristramella simonis'', the short jaw tristramella, is a vulnerable species of cichlid fish from the Jordan River system, including Lake Tiberias (Kinneret), in Israel and Syria, with introduced populations in the Nahr al-Kabir and Orontes basins in Syria. It prefers waters with little or no movement. Along with other tilapias, ''T. simonis'' is commonly caught as a food fish in parts of its range and it is commercially important in Lake Tiberias. Conservation status and taxonomy It is the only member of the genus ''Tristramella'' that remains extant, but it is vulnerable according to the IUCN. Primary threats are water extraction and climate change reducing the rain in its range. Other potential threats are uncontrolled fishing, and outbreaks of a viral disease that causes blindness in tilapia, including ''T. simonis''. The species survives in less than ten locations. The primary location is Lake Tiberias where it remained common, the population was not threatened and fishe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extinct
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxon
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 Linnaean taxonomy, system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard de Jussieu, Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first mad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
