Crenicichla Pellegrini
''Crenicichla pellegrini'' is a species of cichlid native to South America. It is found in the Amazon River basin and in the Aripuanã River basin. This species reaches a length of . The fish is named in honor of French ichthyologist Jacques Pellegrin (1873-1944), as a tribute to his contribution to the knowledge of the genus ''Crenicichla'' and the cichlids in general.

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 ...

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 ...

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 pelle ...

Crenicichla
''Crenicichla'' is a genus of cichlids native to South America commonly known as the pike cichlids. They are found in most tropical and subtropical freshwater habitats between the Andes and the Atlantic. Description The smallest species of ''Crenicichla'' (notably members of the ''C. wallacii'' species group) are no larger than ,Gottwald, J: Crenicichla arten.' and technically qualify as "dwarf cichlids" for the aquarium hobby – though their aggressive and voracious habits should let prospective keepers beware. The biggest pike cichlids can grow to about long. Most ''Crenicichla'' measure in the range of . Like many other predatory fishes, a pike cichlid has a wide mouth and elongated body. Distribution and ecology The genus ''Crenicichla'' is native to freshwater in tropical and subtropical South America east of the Andes, ranging from Trinidad and the Guiana Shield (including Orinoco), through the Amazon and Río de la Plata Basins, south as far as Río Negro in Arg ...

Fish Of The Amazon Basin
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 fis ...

Taxa Named By Alex Ploeg
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ...
