Hypsophrys
''Hypsophrys'' is a small genus of cichlid fishes from Central America. Species There have been two recognized species in this genus: * '' Hypsophrys nematopus'' ( Günther, 1867) (Poor man's tropheus) * ''Hypsophrys nicaraguensis ''Hypsophrys nicaraguensis'', the moga, is a species of cichlid native to the Atlantic slope of Central America, from Nicaragua to Costa Rica.

( Günther, 1864) (Moga) The poor man's tropheus had previously been considered to be in the separate monotypic genus ''Neetroplus'' before it was brought into ''Hypsophrys'' in 2007. However, genetic analysis by Oldřich Říčan, et al. in 2016 demonstrated that the poor man's tropheus should be in a separate genus and resurrected ''Neetroplus'', restating the old scientific name ''Neetroplus nematopus''.

Hypsophrys Nicaraguensis
''Hypsophrys nicaraguensis'', the moga, is a species of cichlid native to the Atlantic slope of Central America, from Nicaragua to Costa Rica. The species is a popular aquarium fish and is traded under a variety of common names that include nickie, parrot cichlid, macaw cichlid, butterfly cichlid and nicaraguense. In Costa Rica it is known as a ''vieja''. Feeding ''Hypsophrys nicaraguensis'' is able to protrude its jaw to 3.8% of its standard length limiting its diet to only 1% evasive prey. Classification The species was formerly the only representative of its genus, and is part of family Cichlidae in subfamily Cichlasomatinae. However, the Poor man's tropheus, formerly ''Neetroplus nematopus'', has also been placed into the genus ''Hypsophrys'', as ''Hypsophrys nematopus''. Conservation It occurs in the Maquenque National Wildlife Refuge Maquenque Wildlife Refuge ( es, Refugio de Vida Silvestre Maquenque), is a protected area in Costa Rica, managed under the Arenal Huetar N ...

Hypsophrys Nematopus
The poor man's tropheus (''Neetroplus nematopus'') is a species of fish in the family Cichlidae. Until 2007 it was the only species in the genus ''Neetroplus'', but at that time it was reclassified into the genus ''Hypsophrys''. In 2016 it was restored to the genus ''Neetroplus'' based on genetic research by Říčan, et al. It is a small-medium-sized cichlid growing to a length of 12 cm. It occurs in Central America in Lake Xiloá, Lake Managua, Lake Masaya and Lake Nicaragua and in riverine habitats on the Atlantic coasts of Costa Rica and Nicaragua. Like most Central American cichlids the species is commonly found in hard, alkaline ( pH 7.5) water. Its diet consists of algae and plant material which it scrapes from rocks and other hard surfaces in a fashion similar to algal grazing cichlids of Lake Malawi in Africa. Some populations are reportedly involved in cleaning other fish of parasites. It also eats chironomid The Chironomidae (informally known as chirono ...

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 ...

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 * ''Chiapaheros'' M ...

Louis Agassiz
Jean Louis Rodolphe Agassiz ( ; ) FRS (For) FRSE (May 28, 1807 – December 14, 1873) was a Swiss-born American biologist and geologist who is recognized as a scholar of Earth's natural history. Spending his early life in Switzerland, he received a PhD at Erlangen and a medical degree in Munich. After studying with Georges Cuvier and Alexander von Humboldt in Paris, Agassiz was appointed professor of natural history at the University of Neuchâtel. He emigrated to the United States in 1847 after visiting Harvard University. He went on to become professor of zoology and geology at Harvard, to head its Lawrence Scientific School, and to found its Museum of Comparative Zoology. Agassiz is known for observational data gathering and analysis. He made institutional and scientific contributions to zoology, geology, and related areas, including multivolume research books running to thousands of pages. He is particularly known for his contributions to ichthyological classification, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Fishes
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 f ...

Central America
Central America ( es, América Central or ) is a subregion of the Americas. Its boundaries are defined as bordering the United States to the north, Colombia to the south, the Caribbean Sea to the east, and the Pacific Ocean to the west. Central America consists of eight countries: Belize, Costa Rica, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, and Panama. Within Central America is the Mesoamerican biodiversity hotspot, which extends from northern Guatemala to central Panama. Due to the presence of several active geologic faults and the Central America Volcanic Arc, there is a high amount of seismic activity in the region, such as volcanic eruptions and earthquakes which has resulted in death, injury, and property damage. In the pre-Columbian era, Central America was inhabited by the indigenous peoples of Mesoamerica to the north and west and the Isthmo-Colombian peoples to the south and east. Following the Spanish expedition of Christopher Columbus' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
