Pelvicachromis Silviae
''Pelvicachromis silviae'' is a species of cichlid in the genus ''Pelvicachromis''. It is found in the Niger River, in the same region as congeners ''Pelvicachromis pulcher'' and ''Pelvicachromis taeniatus''. It was described by Anton Lamboj in 2013. Prior to its formal description it was relatively common in the aquarium fish hobby, denoted as either a subspecies of ''Pelvicachromis subocellatus'' or as an undescribed species similar to ''P. subocelatus'', ''Pelvicachromis sp. aff. subocellatus.'' Lamboj concurs that it is more closely related to ''P. subocellatus'' than to other ''Pelvocachromis'' species and regards it as part of the ''P. subocellatus'' group within the genus ''Pelvicachromis''. Lamboj named ''P. silviae'' after his wife Silvia, to thank her for supporting his scientific work. Although similar in appearance to ''P. subocellatus'' and the more common ''P. pulcher'', it has a deeper body than either species. The main body color is pale or yellowish brown, ...

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 ...

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 ...

Niger River
The Niger River ( ; ) is the main river of West Africa, extending about . Its drainage basin is in area. Its source is in the Guinea Highlands in south-eastern Guinea near the Sierra Leone border. It runs in a crescent shape through Mali, Niger, on the border with Benin and then through Nigeria, discharging through a massive delta, known as the Niger Delta (or the Oil Rivers), into the Gulf of Guinea in the Atlantic Ocean. The Niger is the third-longest river in Africa, exceeded by the Nile and the Congo River. Its main tributary is the Benue River. Etymology The Niger has different names in the different languages of the region: * Fula: ''Maayo Jaaliba'' * Manding: ''Jeliba'' or ''Joliba'' "great river" * Tuareg: ''Egerew n-Igerewen'' "river of rivers" * Songhay: ''Isa'' "the river" * Zarma: ''Isa Beeri'' "great river" * Hausa: ''Kwara'' *Nupe: ''Èdù'' * Yoruba: ''Ọya'' "named after the Yoruba goddess Ọya, who is believed to embody the ri ...

Pelvicachromis Pulcher
''Pelvicachromis pulcher'' is a freshwater fish of the cichlid family, endemic to Nigeria and Cameroon. It is popular amongst aquarium hobbyists, and is most commonly sold under the name kribensis, although it has other common names, including various derivatives and color morphs of the kribensis: krib, common krib, red krib, super-red krib and rainbow krib, along with rainbow cichlid and purple cichlid. Description In the wild, male ''P. pulcher'' grow to a maximum length of approximately and a maximum weight of . Females are smaller and deeper bodied, growing to a maximum length of and a maximum weight of . Both sexes have a dark longitudinal stripe that runs from the caudal fin to the mouth and pink to red abdomens, the intensity of which changes during courtship and breeding. The dorsal and caudal fins also may bear gold-ringed eye spots or ocelli. Males show colour polymorphisms in some populations collected at single localities. Juveniles are monomorphic until appro ...

Pelvicachromis Taeniatus
''Pelvicachromis taeniatus'' is a species of cichlid from Benin and Nigeria that is occasionally kept as an aquarium fish. It is native to the soft-water rivers. This species can reach a length of SL. It is known to exist in a variety of geographically restricted varieties distinguished by differences in coloration. These are often given names such as "Nigerian red" or "Moliwe" that refer to the places where each variety is collected. The species ''P. taeniatus'' formerly included populations from Cameroon. A 2014 study by Lamboj, Bartel & dell’Ampio found that the Cameroon populations were a different species from the Nigeria populations, and identified the Cameroon populations as belonging to the species ''Pelvicachromis kribensis'' and ''Pelvicachromis drachenfelsi''. Lamboj, Bartel & dell’Ampio found that ''P. kribensis'', ''P. drachenfelsi''and ''P. taeniatus'' are closely related and form a clade within the genus ''Pelvicachromis'', which they described as the "''P ...

Dorsal Fin
A dorsal fin is a fin located on the back of most marine and freshwater vertebrates within various taxa of the animal kingdom. Many species of animals possessing dorsal fins are not particularly closely related to each other, though through convergent evolution they have independently evolved external superficial fish-like body plans adapted to their marine environments, including most numerously fish, but also mammals such as cetaceans (whales, dolphins, and porpoises), and even extinct ancient marine reptiles such as various known species of ichthyosaurs. Most species have only one dorsal fin, but some have two or three. Wildlife biologists often use the distinctive nicks and wear patterns which develop on the dorsal fins of large cetaceans to identify individuals in the field. The bony or cartilaginous bones that support the base of the dorsal fin in fish are called ''pterygiophores''. Functions The main purpose of the dorsal fin is to stabilize the animal against rollin ...

Caudal Fin
Fins are distinctive anatomical features composed of bony spines or rays protruding from the body of a fish. They are covered with skin and joined together either in a webbed fashion, as seen in most bony fish, or similar to a flipper, as seen in sharks. Apart from the tail or caudal fin, fish fins have no direct connection with the spine and are supported only by muscles. Their principal function is to help the fish swim. Fins located in different places on the fish serve different purposes such as moving forward, turning, keeping an upright position or stopping. Most fish use fins when swimming, flying fish use pectoral fins for gliding, and frogfish use them for crawling. Fins can also be used for other purposes; male sharks and mosquitofish use a modified fin to deliver sperm, thresher sharks use their caudal fin to stun prey, reef stonefish have spines in their dorsal fins that inject venom, anglerfish use the first spine of their dorsal fin like a fishing rod to lu ...
