Caquetaia
''Caquetaia'' is a small genus of cichlid fishes from tropical South America. The genus currently contains three species. ''Caquetaia spp.'' are ambush predators that predominantly feed on invertebrates. Seasonal fluctuations in water level have been shown to contribute to ''Caquetaia spp.'' consuming a larger variety of invertebrates, especially when the water level is low during dry seasons. ''Caquetaia'' are known for their highly protrusible jaws, an adaptation hypothesized to improve their ability to capture prey by enhancing overall ram velocity. Species There are currently three recognized species in this genus: * '' Caquetaia kraussii'' (Steindachner, 1878) * '' Caquetaia myersi'' ( L. P. Schultz, 1944) * '' Caquetaia spectabilis'' (Steindachner Franz Steindachner (11 November 1834 in Vienna – 10 December 1919 in Vienna) was an Austrian zoologist, ichthyologist, and herpetologist.

Caquetaia Myersi
''Caquetaia myersi'' is a species of fish, a large predatory cichlid, which is endemic to the basin of the Amazon River, specifically the Putumayo and Napo rivers of Ecuador and Colombia. The specific name honours the American ichthyologist George S. Myers (1905-1985) of Stanford University Stanford University, officially Leland Stanford Junior University, is a private research university in Stanford, California. The campus occupies , among the largest in the United States, and enrolls over 17,000 students. Stanford is consider ..., who first noticed that this was a different species of fish but did not formally describe it. The fish is a protrusible-mouthed predator. The juveniles are omnivorous but the large adults are carnivorous.

Turquoise Cichlid
The turquoise cichlid (''Kronoheros umbriferus''), also known as the umbee cichlid, is a species of cichlid fish found in freshwater habitats of eastern Panama and central and western Colombia. It is commonly caught as a food fish, and sometimes kept in aquariums. This robust fish is the largest cichlid native to its range, up to in weight and long, and in the Americas only certain peacock bass and the wolf cichlid may reach a greater size. Females of the turquoise cichlid remain significantly smaller than males. It is strongly predatory, typically feeding on fish and other small animals, but it may also take fruits and seeds. Taxonomy and appearance This cichlid was first scientifically described in 1913 based on specimens from the Cupe River, which is a part of the Tuira River basin in Panama. It was placed in '' Cichlasoma'', which at the time was a wastebasket genus. As the species clearly belonged elsewhere, it was subsequenctly moved to '' Heros'' or ''Caquetaia'', ...

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 * '' Chiapa ...

Henry Weed Fowler
Henry Weed Fowler (March 23, 1878 – June 21, 1965) was an American zoologist born in Holmesburg, Pennsylvania. He studied at Stanford University under David Starr Jordan. He joined the Academy of Natural Sciences in Philadelphia and worked as an assistant from 1903 to 1922, associate curator of vertebrates from 1922 to 1934, curator of fish and reptiles from 1934 to 1940 and curator of fish from 1940 to 1965. He published material on numerous topics including crustaceans, birds, reptiles and amphibians, but his most important work was on fish. In 1927 he co-founded the American Society of Ichthyologists and Herpetologists and acted as treasurer until the end of 1927. In 1934 he went to Cuba, alongside Charles Cadwalader (president of the Academy of Natural Sciences of Philadelphia), at the invitation of Ernest Hemingway to study billfishes, he stayed with Hemingway for six weeks and the three men developed a friendship which continued after this trip and Hemingway sent speci ...

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 ...

South America
South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a relatively small portion in the Northern Hemisphere at the northern tip of the continent. It can also be described as the southern subregion of a single continent called America. South America is bordered on the west by the Pacific Ocean and on the north and east by the Atlantic Ocean; North America and the Caribbean Sea lie to the northwest. The continent generally includes twelve sovereign states: Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Guyana, Paraguay, Peru, Suriname, Uruguay, and Venezuela; two dependent territories: the Falkland Islands and South Georgia and the South Sandwich Islands; and one internal territory: French Guiana. In addition, the ABC islands of the Kingdom of the Netherlands, Ascension Island (dependency of Saint Helena, Ascension and Tristan da Cunha, a British Overseas Territory), Bouvet Island ( dependency of Norway), Pa ...

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] |
