Phoxinus Strymonicus
''Phoxinus strymonicus'', the Aegean minnow, is a species of freshwater ray-finned fish belonging to the family Leuciscidae, which includes the daces, minnows and related fishes. This fish is endemic to the northeastern Greece. Taxonomy ''Phoxinus strymonicus'' was first formally described in 2007 by the Swiss ichthyologist Maurice Kottelat with its type locality given as " Strymon drainage, Angitis system, canals near Kalambaki, about 14 kilometers south of Drama, Macedonia, Greece". Kottelat was studying the variation in populations of what were thought to be "common minnows ''Phoxinus phoxinus'' ''sensu lato'' and discovered that what had been thought to be a single widespread Palearctic species was, in fact, a species complex. This species is classified within the genus ''Phoxinus'', the Eurasian minnows, within the monotypic subfamily Phoxininae of the family Leuciscidae. Etymology ''Phoxinus strymonicus'' belongs to the genus ''Phoxinus'', this name is derived from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Standard Length
Fish measurement is the measuring of individual fish and various parts of fish anatomy, their anatomies, for data used in many areas of ichthyology, including Taxonomy (biology), taxonomy and fishery 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 Glossary of ichthyology#H, hypural plate. This measurement excludes the length of the caudal fin, 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 Actinopterygii, bony fish), while total length measurements are used with Myxini (hagfish), Petromyzontiformes (lampreys) and usually Elasmobranchii (shark ...

Dorsal Fin
A dorsal fin is a fin on the back of most marine and freshwater vertebrates. Dorsal fins have evolved independently several times through convergent evolution adapting to marine environments, so the fins are not all homologous. They are found in most fish, in mammals such as whales, and in extinct ancient marine reptiles such as ichthyosaurs. Most have only one dorsal fin, but some have two or three. Wildlife biologists often use the distinctive nicks and wear patterns which develop on the dorsal fins of whales to identify individuals in the field. The bones or cartilages that support the dorsal fin in fish are called pterygiophores. Functions The main purpose of the dorsal fin is usually to stabilize the animal against rolling and to assist in sudden turns. Some species have further adapted their dorsal fins to other uses. The sunfish uses the dorsal fin (and the anal fin Fins are moving appendages protruding from the body of fish that interact with water to ge ...

Anal Fin
Fins are moving appendages protruding from the body of fish that interact with water to generate thrust and help the fish swim. Apart from the tail or caudal fin, fish fins have no direct connection with the back bone and are supported only by muscles. Fish fins are distinctive anatomical features with varying structures among different clades: in ray-finned fish (Actinopterygii), fins are mainly composed of bony spines or rays covered by a thin stretch of scaleless skin; in lobe-finned fish ( Sarcopterygii) such as coelacanths and lungfish, fins are short rays based around a muscular central bud supported by jointed bones; in cartilaginous fish ( Chondrichthyes) and jawless fish ( Agnatha), fins are fleshy " flippers" supported by a cartilaginous skeleton. Fins at different locations of the fish body serve different purposes, and are divided into two groups: the midsagittal ''unpaired fins'' and the more laterally located ''paired fins''. Unpaired fins are pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet, species epithet, or epitheton) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Etymology Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the ...

Tautonym
A tautonym is a scientific name of a species in which both parts of the name have the same spelling, such as '' Rattus rattus''. The first part of the name is the name of the genus and the second part is referred to as the ''specific epithet'' in the ''International Code of Nomenclature for algae, fungi, and plants'' and the ''specific name'' in the ''International Code of Zoological Nomenclature''. Tautonymy (i.e., the usage of tautonymous names) is permissible in zoological nomenclature (see List of tautonyms for examples). In past editions of the zoological code, the term tautonym was used, but it has now been replaced by the more inclusive "tautonymous names"; these include trinomial names for subspecies such as '' Gorilla gorilla gorilla'' and '' Bison bison bison''. Tautonyms can be formed when animals are given scientific names for the first time, or when they are reclassified and given new scientific names. An example of the former is the hidden mirror skipper of Braz ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Constantine Samuel Rafinesque
Constantine Samuel Rafinesque-Schmaltz (; 22 October 178318 September 1840) was a French early 19th-century polymath born near Constantinople in the Ottoman Empire and self-educated in France. He traveled as a young man in the United States, ultimately settling in Ohio in 1815, where he made notable contributions to botany, zoology, and the study of Mound Builders, prehistoric earthworks in North America. He also contributed to the study of ancient Mesoamerican languages, Mesoamerican linguistics, in addition to work he had already completed in Europe. Rafinesque was an eccentric and erratic genius. He was an autodidact, who excelled in various fields of knowledge, as a zoologist, botanist, writer and Polyglot (person), polyglot. He wrote prolifically on such diverse topics as anthropology, biology, geology, and linguistics, but was honored in none of these fields during his lifetime. Indeed, he was an outcast in the American scientific community and his submissions were automati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Linnaeus
Carl Linnaeus (23 May 1707 – 10 January 1778), also known after ennoblement in 1761 as Carl von Linné,#Blunt, Blunt (2004), p. 171. was a Swedish biologist and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern Taxonomy (biology), taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was the son of a curate and was born in Råshult, in the countryside of Småland, southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pierre Belon
Pierre Belon (1517–1564) was a French traveller, natural history, naturalist, writer and diplomat. Like many others of the Renaissance period, he studied and wrote on a range of topics including ichthyology, ornithology, botany, comparative anatomy, architecture and Egyptology. He is sometimes known as Pierre Belon du Mans, or, in the Latin in which his works appeared, as Petrus Bellonius Cenomanus. The Russian physiologist Ivan Pavlov (known for Ivan Pavlov#Legacy, Pavlov's dogs) called him the "prophet of comparative anatomy". Life Belon was born in 1517 at the hamlet of Souletière near Cérans-Foulletourte in the Pays de la Loire. Nothing is known about his descent. Somewhere between 1532 and 1535 he started working as an apprentice to René des Prez, born in Foulletourte but by then an apothecary to the bishop of Clermont, Guillaume Duprat. Between 1535 and 1538 he entered the service of René du Bellay, bishop of Le Mans, who allowed him to study medicine at the University ...
