Rocio Octofasciata
The Jack Dempsey (''Rocio octofasciata'') is a species of cichlid fish that is native to freshwater habitats from southern Mexico to Honduras, but also introduced elsewhere. Its common name refers to its aggressive nature and strong facial features, likened to that of the famous 1920s boxer Jack Dempsey. Animal-World.com Distribution The fish is native to freshwater habitats from southern Mexico to Honduras, where it is found in slow-moving waters, such as swampy areas with warm, murky water, weedy, mud- and sand-bottomed canals, drainage ditches, and rivers. It is also established as an |
Cichlid Genera
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 aquar ...

Jacques Pellegrin
Jacques Pellegrin (12 June 1873, Paris – 12 August 1944) was a French zoologist. In Paris, he worked under zoologist Léon Vaillant (chair of reptiles and fishes) at the ''Muséum national d'histoire naturelle''. From 1897, Pellegrin served as ''préparateur'' at the museum. He obtained doctorates in medicine (1899) and science (1904), and in 1908 was named as an assistant director. After many missions abroad, he became sub-director of the museum in 1937, and replaced Louis Roule (1861–1942) as the chairperson of herpetology and ichthyology. He published over 600 scientific books and articles and discovered around 350 new species. He named a number of fishes from the family Cichlidae, such as the genera '' Astatoreochromis'', '' Astatotilapia'', '' Boulengerochromis'', ''Lepidiolamprologus'', '' Nanochromis'' and '' Ophthalmotilapia''. Taxa named in his honor He has the following species named in his honor: * The Clingfish '' Apletodon pellegrini'' * ''Enteromius pe ...

Fish Of Central America
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. Mos ...

Synonym (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, '' Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cichlasoma
''Cichlasoma'' is a genus of freshwater fish in the cichlid family. The genus was previously very large (a wastebasket taxon), including cichlids from North America, including Central America, and South America. Reclassification and subsequent splitting of the genus by Sven O. Kullander and other ichthyologists has resulted in removing many of the former species from ''Cichlasoma'' to genera such as ''Amphilophus'', '' Archocentrus'', ''Herichthys'', '' Heros'', '' Nandopsis'', ''Parachromis'', '' Thorichthys'', '' Vieja'' and others in the tribe Heroini. Species According to FishBase, there are currently sixteen recognized species in this genus, but three very different Middle American taxa ("''C.''"'' geddesi'' a synonym of ''Herichthys deppii'', and "''C.''"'' istlanum'' and "''C.''"'' trimaculatum'' placed in ''Amphilophus'') are not included by Catalog of Fishes, effectively limiting ''Cichlasoma'' to a group of rather similar, medium-small cichlids of South America. * ...
