Gymnogeophagus Tiraparae
''Gymnogeophagus tiraparae'' is a species of Geophagine cichlid. Before the scientific description, this fish was referred to with the name ''Gymnogeophagus sp "San Borja"''. It is found in Rio Negro in Uruguay and Tacuari River in the Laguna Mirim basin. It has a distinct hump on the head. The body is laterally compressed. The largest specimens found have had a standard length of 13 cm. ''Gymnogeophagus tiraparae'' inhabits large rivers with clear water. This species is probably closely related to ''Gymnogeophagus gymnogenys ''Gymnogeophagus'' is a genus of cichlid fishes from South America, where they are known from various river basins (notably Rio de la Plata and Lagoa dos Patos– Mirim) in southern Brazil, Paraguay, Uruguay and northern Argentina.

Iván González-Bergonzoni
Ivan () is a Slavic male given name, connected with the variant of the Greek name (English: John) from Hebrew meaning 'God is gracious'. It is associated worldwide with Slavic countries. The earliest person known to bear the name was Bulgarian tsar Ivan Vladislav. It is very popular in Russia, Ukraine, Croatia, Serbia, Bosnia and Herzegovina, Slovenia, Bulgaria, Belarus, North Macedonia, and Montenegro and has also become more popular in Romance-speaking countries since the 20th century. Etymology Ivan is the common Slavic Latin spelling, while Cyrillic spelling is two-fold: in Bulgarian, Russian, Macedonian, Serbian and Montenegrin it is Иван, while in Belarusian and Ukrainian it is Іван. The Old Church Slavonic (or Old Cyrillic) spelling is . It is the Slavic relative of the Latin name , corresponding to English '' John''. This Slavic version of the name originates from New Testament Greek (''Iōánnēs'') rather than from the Latin . The Greek ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sebastián Oviedo
Saint Sebastian (in Latin: ''Sebastianus''; Narbonne, Narbo, Gallia Narbonensis, Roman Empire c. AD 255 – Rome, Roman Italy, Italia, Roman Empire c. AD 288) was an early Christianity, Christian saint and martyr. According to traditional belief, he was killed during the Diocletianic Persecution of Christians. He was initially tied to a post or tree and shot with arrows, though this did not kill him. He was, according to tradition, rescued and healed by Saint Irene of Rome, which became a popular subject in 17th-century painting. In all versions of the story, shortly after his recovery he went to Diocletian to warn him about his sins, and as a result was clubbed to death. He is venerated in the Roman Catholic Church, Catholic Church and the Eastern Orthodox Church, Orthodox Church. The oldest record of the details of Sebastian's martyrdom is found in the ''Chronograph of 354'', which mentions him as a martyr, venerated on January 20. He is also mentioned in a sermon on Psalm 11 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geophaginae
Geophagini is a tribe of cichlids from the subfamily Cichlinae, the American cichlids. It is the sister taxon to the clade which includes the Cichlasomatini and Heroini. Fishes in the Geophagini are distributed from Panama south to Argentina, it is the most speciose of the seven tribes within the Cichlinae and it is subdivided into three sub-tribes, Acarichthyina, Crenicaratina, and Geophagina which together contain over 200 species. Geophagines show morphological and behavioural specialisations to enable them to sift the substrates within their mouths so that they can separate benthic invertebrates from substrates dominated by sand or silt. Classification The Geophagini are classified as follows: * Subtribe Acarichthyina Kullander, 1998 ** Genus '' Acarichthys'' C. H. Eigenmann, 1912 ** Genus ''Guianacara'' Kullander & Nijssen, 1989 * Subtribe Crenicaratina Kullander, 1998 ** Genus ''Biotoecus'' C. H. Eigenmann & C. H. Kennedy, 1903 ** Genus ''Crenicara'' Steindachner, 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cichlid
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 aquariu ...

Binomial Nomenclature
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or 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 (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. 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 ''Homo sapiens''. ''Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is credit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Río Negro (Uruguay)
The Río Negro (, ''Black River'') is a river in southern Brazil and central Uruguay. It originates in the southern highlands of Brazil, just east of Bagé, and flows west across the entire width of Uruguay to the Uruguay River. The course of the Río Negro across Uruguay effectively divides the south of the country from the north. The Río Negro's principal tributaries are Yí River and Tacuarembó River. The river is dammed near Paso de los Toros, creating the Rincón del Bonete Reservoir, also called the Gabriel Terra Reservoir or the Rio Negro Reservoir. With a surface area of about , it is the largest reservoir in Uruguay and an installed capacity of 160 MW. Downstream from the Rincón del Bonete Reservoir, there are two more dams, the Baygorria Dam and the Constitución Dam at Palmar, [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uruguay
Uruguay (; ), officially the Oriental Republic of Uruguay ( es, República Oriental del Uruguay), is a country in South America. It shares borders with Argentina to its west and southwest and Brazil to its north and northeast; while bordering the Río de la Plata to the south and the Atlantic Ocean to the southeast. It is part of the Southern Cone region of South America. Uruguay covers an area of approximately and has a population of an estimated 3.4 million, of whom around 2 million live in the metropolitan area of its capital and largest city, Montevideo. The area that became Uruguay was first inhabited by groups of hunter–gatherers 13,000 years ago. The predominant tribe at the moment of the arrival of Europeans was the Charrúa people, when the Portuguese first established Colónia do Sacramento in 1680; Uruguay was colonized by Europeans late relative to neighboring countries. The Spanish founded Montevideo as a military stronghold in the early 18th century bec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lagoa Mirim
Lagoon Mirim (Portuguese, ) or Merín (Spanish, ) is a large estuarine lagoon which extends from southern Rio Grande do Sul state in Brazil into eastern Uruguay. Lagoa Mirim is separated from the Atlantic Ocean by a sandy, partially barren isthmus. The Jaguarão/Yaguarón, Tacuarí and Cebollatí Rivers empty into Lagoon Mirim, while the São Gonçalo Channel connects it with Lagoa dos Patos to the north. Location Lagoon Mirim is about long by wide and in area. It is more irregular in outline than its larger neighbor to the north, Lagoa dos Patos, and discharges into the latter through São Gonçalo Channel, which is navigable by small boats. Lagoa Mirim has no direct connection to the Atlantic, but the Rio Grande, a tidal channel about long which connects Lagoon dos Patos to the Atlantic, affords an entrance to the navigable inland waters of both lagoons and several small ports. Both lagoons are the remains of an ancient depression in the coastline shut in by sand beaches ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Measurement
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.
