Cichlids
Cichlids are fish from the family (biology), 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 Pholidichthys leucotaenia, 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 Binomial nomenclature, scientifically described, making it one of the largest vertebrate families. New species are discovered annually, and many species remain Undescribed taxon, 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'' spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geophagini
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.

Sven O
Sven (in Danish and Norwegian, also Svend and also in Norwegian most commonly Svein) is a Scandinavian first name which is also used in the Low Countries and German-speaking countries. The name itself is Old Norse for "young man" or "young warrior". The original spelling in Old Norse was ''sveinn''. Over the centuries, many northern European rulers have carried the name including Sweyn I of Denmark (Sven Gabelbart). An old legend relates the pagan king Blot-Sven ordered the execution of the Anglo-Saxon monk Saint Eskil. In medieval Swedish, "sven" (or "sven av vapen" (sven of arms)) is a term for squire. The female equivalent, Svenja, though seemingly Dutch and Scandinavian, is not common anywhere outside of German-speaking countries. Sven can also be spelled with W, Swen, but is pronounced as Sven. The Icelandic version of Sven/Svend is Sveinn (); the Faroese version is Sveinur (). Entertainment and music * Sven Einar Englund, Finnish composer * Sven Epiney, Swiss televis ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. 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 ...

Mazaruni River
The Mazaruni River is a tributary of the Essequibo River in northern Guyana. Its source is in the remote western forests of the Pakaraima Mountains and its confluence with the Cuyuni River is near Bartica. As it descends from the Guiana Highlands the river runs south-east, past Issano, then northward to Bartica. The river is a source of alluvial gold. Sources The river takes source in the Roraima Plateau, three levels of sandstones and conglomerates, crowned by Mt. Roraima (). In Guyana, the two highest levels of the Roraima Plateau are known as Pakaraima Mountains and Merume Mountains. The source of the Mazarunu River is in the Merume Mountains. The area is one of the very few places in the world still inaccessible. In 1992, a joint expedition of the Guyana Defence Force and Welsh Guards members was unable to reach the source of Mazaruni River, even with training, finances and equipment. Course The river drops down from each Roraima plateau through three steep sided canyo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Essequibo River
The Essequibo River (Spanish: ''RÃo Esequibo'' originally called by Alonso de Ojeda ''RÃo Dulce'') is the largest river in Guyana, and the largest river between the Orinoco and Amazon. Rising in the Acarai Mountains near the Brazil–Guyana border, the Essequibo flows to the north for through forest and savanna into the Atlantic Ocean. With a total drainage basin of and an average discharge of . Territory near the river is argued over by Venezuela and Guyana. Venezuela considers that the natural border according to the divortium aquarum that delimits the eastern margin of that country with the Cooperative Republic of Guyana is "by law", although due to the territorial dispute between the two countries for the sovereignty of Guayana Esequiba, it is "De facto administered and occupied for the most part by the former English colony of British Guiana, present-day Guyana.

Guyana
Guyana ( or ), officially the Cooperative Republic of Guyana, is a country on the northern mainland of South America. Guyana is an indigenous word which means "Land of Many Waters". The capital city is Georgetown. Guyana is bordered by the Atlantic Ocean to the north, Brazil to the south and southwest, Venezuela to the west, and Suriname to the east. With , Guyana is the third-smallest sovereign state by area in mainland South America after Uruguay and Suriname, and is the second-least populous sovereign state in South America after Suriname; it is also one of the least densely populated countries on Earth. It has a wide variety of natural habitats and very high biodiversity. The region known as "the Guianas" consists of the large shield landmass north of the Amazon River and east of the Orinoco River known as the "land of many waters". Nine indigenous tribes reside in Guyana: the Wai Wai, Macushi, Patamona, Lokono, Kalina, Wapishana, Pemon, Akawaio and Warao. Histo ...

Dwarf Cichlid
Dwarf cichlid is a term used by fishkeeping hobbyists to describe an arbitrary assemblage of small-sized fish from the family Cichlidae. Although the grouping is widely used in the aquarium industry and hobby, the grouping has no taxonomic or ecological basis and is poorly defined.Linke H, Staeck L (1994) ''American cichlids I: Dwarf Cichlids. A handbook for their identification, care and breeding.'' Tetra Press. Germany. Though dwarf cichlids are by definition small-sized cichlids, there is no accepted maximum length of a dwarf-sized cichlid. Some authors suggest a maximum of 10 centimetres (3.9 in.), while other suggest a maximum length of 12 centimetres (4.7 in.).Richter H-J (1989) ''Complete Book of Dwarf Cichlids.'' Tropical Fish Hobbyist, USA The term is most frequently used to describe small South American or West African species which are suitable for soft, acidic ( pH 4 to 7) densely planted aquariums, however, some aquarists and authors include within this "dwarf cichli ...

Hernán López-Fernández
Hernán is a Spanish masculine given name, originating from Germanic Hernan in the Visigoth culture in Spain. It is the Latinized version of the compound name ''Fard-nanth'', which seems to mean "gentle traveler" or "spiritual traveler". The House of Hernán gave its name to those with the surname Hernández, the -ez at the end denoting membership of that House. The surname, like many Spanish surnames, is of Teutonic-Gothic origin. It is not connected with "Herman" - also of Germanic origin, but a different one. Persons with the given name include: * Hernán Alvarado Solano (1946–2011), Colombian Roman Catholic bishop * Hernán Andrade (born 1960), Mexican racewalker * Hernán Barcos (born 1984), Argentinian football player * Hernán Barreneche (born 1939), retired long-distance runner * Hernán Behn (19th century), Puerto Rican businessperson * Hernán Bernardello (born 1986), Argentine football midfielder * Hernán Boyero (born 1979), Argentine football striker * Hernán Bà ...
