Heros (fish)
''Heros'' is a genus of cichlids native to the Amazon, Orinoco and Essequibo River basins in South America.Staeck, W. & Schindler, I. (2015): Description of a new ''Heros'' species (Teleostei, Cichlidae) from the Rio Orinoco drainage and notes on ''Heros severus'' Heckel, 1840. ''Bulletin of Fish Biology, 15 (1/2): 121-136.'' They were previously included in the genus ''Cichlasoma'' before its restriction to the distinct group of "Port Cichlids." The ''Heros'' species most commonly encountered in the aquarium trade are fish referable to the species ''Heros efasciatus''. However, the trade name generally used is "Severum Cichlids." Trade fish are very often line bred specimens of color sports such as "Super Red Severums" or "Gold Severums." The provenance of these is not clear, but they seem to have been derived from the base "Green Severum" form that is most closely identified with ''H. efasciatus.'' Species There are currently five recognized species in this genus: * ''Heros e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johann Jakob Heckel
Johann Jakob Heckel (23 January 1790 – 1 March 1857) was an Austrian taxidermist, zoologist, and ichthyologist from Mannheim in the Electoral Palatinate. Life Though not a formally trained biologist, he worked his way up through the ranks to eventually become the director of the Fish Collection at the Naturhistorisches Museum in Vienna. For the most part, he was not a traveler or explorer like many of the scientists of the time, he remained in Vienna, where he studied and catalogued specimens sent to him from the field. Among those who brought specimens to him were Karl Alexander Hügel, Joseph Russegger and Theodor Kotschy — involving collection activities in Kashmir, the Middle East and northeastern Africa that greatly enriched the Vienna museum. Fish were his specialty and he worked with many of the greatest ichthyologists of his time including Cuvier, Valenciennes, Bonaparte, Müller, and Troschel.

Wolfgang Staeck
Wolfgang is a German male given name traditionally popular in Germany, Austria and Switzerland. The name is a combination of the Old High German words '' wolf'', meaning "wolf", and '' gang'', meaning "path", "journey", "travel". Besides the regular "wolf", the first element also occurs in Old High German as the combining form "-olf". The earliest reference of the name being used was in the 8th century. The name was also attested as "Vulfgang" in the Reichenauer Verbrüderungsbuch in the 9th century. The earliest recorded famous bearer of the name was a tenth-century Saint Wolfgang of Regensburg. Due to the lack of conflict with the pagan reference in the name with Catholicism, it is likely a much more ancient name whose meaning had already been lost by the tenth century. Grimm ('' Teutonic Mythology'' p. 1093) interpreted the name as that of a hero in front of whom walks the "wolf of victory". A Latin gloss by Arnold of St Emmeram interprets the name as ''Lupambulus''.E. F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heroini
Heroini is a fish tribe from the Cichlasomatinae subfamily in the cichlid family. All cichlids native to the Greater Antilles, United States (southern Texas), Mexico and northern Central America are members of this tribe. It also includes most cichlid species in southern Central America (where only non-Heroini cichlids are '' Andinoacara'' and '' Geophagus'') and several species from South America (where several other tribes exist). A large percentage of its species were formerly placed in the genus '' Cichlasoma'' (itself now placed in the tribe Cichlasomatini), but have since been moved to other genera. In other classifications the tribe Heroini is placed in the subfamily Cichlinae. Abstract Genera This tribe include about 35 genus and 160 species: * ''Amatitlania'' Schmitter-Soto, 2007 * '' Amphilophus'' Agassiz, 1859 * ''Archocentrus'' Gill, 1877 * '' Astatheros'' Pellegrin, 1904 * '' Australoheros'' Říčan & Kullander, 2006 * '' Caquetaia'' Fowler, 1945 * '' Chiapa ...

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 ...

Heros Liberifer
''Heros liberifer'' is a species of tropical cichlid native to lentic habitats, especially flooded forests, in the upper and middle Orinoco basin in South America. Up until 2014 the liberifer was incorrectly believed to be the previously defined H. severus that was defined in 1840 by Heckel ite Heros severus can be differentiated by having a partially formed band unlike other Heros as well as having a red shoulders. This band was originally defined by Heckel however it was dismissed as an anomaly by Kullander(1986) in the collected species. With the finding of the true H. severum, Staek & Shindler officially classified the liberifer so as to make room for the true H. severus. Description H. liberifer can be distinguished from other Heros species due to its small spots that form horizontal lines across the lower half of its body. Other traits of the liberifer are a caudal spot in adult specimen as well as, generally narrower lips than other species. Aquarium trade This species ...

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 ...
