Perissodini
Perissodini is a tribe of African cichlids, containing three genera of freshwater fish found only in Lake Tanganyika. One of its genera, '' Haplotaxodon'', feeds on small fish and zooplankton Zooplankton are the heterotrophic component of the planktonic community (the " zoo-" prefix comes from ), having to consume other organisms to thrive. Plankton are aquatic organisms that are unable to swim effectively against currents. Consequent .... The other two genera are specialised in eating scales from other fish. They are all mouthbrooders.Smith, M.P. (1998). Lake Tanganyikan Cichlids, pp. 11—13.

Lake Tanganyika
Lake Tanganyika ( ; ) is an African Great Lakes, African Great Lake. It is the world's List of lakes by volume, second-largest freshwater lake by volume and the List of lakes by depth, second deepest, in both cases after Lake Baikal in Siberia. It is the world's longest freshwater lake. The lake is shared among four countries—Tanzania, the Democratic Republic of the Congo (the DRC), Burundi, and Zambia—with Tanzania (46%) and the DRC (40%) possessing the majority of the lake. It drains via the Lukuga River into the Congo River system, which ultimately discharges at Banana, Democratic Republic of the Congo into the Atlantic Ocean. Geography Lake Tanganyika is situated within the Albertine Rift, the western branch of the East African Rift, and is confined by the mountainous walls of the valley. It is the largest rift lake in Africa and the second-largest freshwater lake by volume in the world. It is the deepest lake in Africa and holds the greatest volume of fresh water on the ...

Cichlid
Cichlids () are a large, diverse, and widespread family of percomorph fish in the family Cichlidae, order Cichliformes. At least 1,760 species have been scientifically described, making it one of the largest vertebrate families, with only the Cyprinidae being more speciose. 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. They are native to the Neotropics, Africa (including Madagascar), the Middle East, and the Indian subcontinent, although some species have been introduced worldwide. 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 aquarium fish kept by hobbyists, including the angelfish, oscars, and discus. Cichlids have the largest number of endangered species among vertebrate families, most in the haplochrom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lepidophagy
Lepidophagy is a specialised feeding behaviour in fish that involves eating the scales of other fish. Lepidophagy is widespread, having evolved independently in at least five freshwater families and seven marine families. A related feeding behavior among fish is pterygophagy: feeding on the fins of other fish. Species Lepidophagy, or scale-eating, has been reported in a range of fish, including: '' Chanda nama'' (family Ambassidae), '' Plagiotremus'' (family Blenniidae), ''Terapon jarbua'' (family Terapontidae), a few '' Ariopsis'' and '' Neoarius'' species (family Ariidae), '' Pachypterus khavalchor'' (family contentious - variably in Schilbeidae, Bagridae, or Horabagridae), '' Macrorhamphoides uradoi'' (family Triacanthodidae), several pencil catfish (family Trichomycteridae), some piranha, '' Exodon paradoxus'', '' Probolodus'', '' Roeboides'' and '' Roeboexodon'' species (order Characiformes), '' Cyprinodon desquamator'' (family Cyprinodontidae), along with both '' Perissodu ...

Perissodus Microlepis
''Perissodus microlepis'' is a species of cichlid endemism, endemic to Lake Tanganyika. It can also be found in the aquarium trade. This species reaches a length of fish measurement, TL. It is a scale-eating 'parasite' on other fish species. It occurs in two distinct morphological forms. One morph (biology), morph has mouth parts twisted to the left, enabling it to eat scales off its victim's right flank. In contrast, the other morph, whose mouth is twisted to the right, eats scales off its victim's left flank. The relative abundance of the two morphs in populations is regulated by frequency-dependent selection.Stewart, T. A. and Albertson, R. C.

Max Poll
Max Fernand Leon Poll (21 July 1908 in Ruisbroek – 13 March 1991 in Uccle) was a Belgian ichthyologist who specialised in the Cichlidae. In the years 1946 and 1947 he organised an expedition to Lake Tanganyika. He has described several species of Pseudocrenilabrinae, such as '' Lamprologus signatus'', '' Steatocranus casuarius'', '' Neolamprologus brichardi'', and '' Neolamprologus pulcher''. He was a member of The Royal Academies for Science and the Arts of Belgium, professor at the Université libre de Bruxelles, and conservator at the Royal Museum of the Belgian Congo in Tervuren. He was an honorary member of the American Society of Ichthyologists and Herpetologists. Taxon named in his honor Named after him are species and taxa In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit.

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. 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 of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Tribe (biology)
In biology, a tribe is a taxonomic rank above genus, but below family and subfamily. It is sometimes subdivided into subtribes. By convention, all taxa ranked above species are capitalized, including both tribe and subtribe. In zoology, the standard ending for the name of a zoological tribe is "-ini". Examples include the tribes Caprini (goat-antelopes), Hominini (hominins), Bombini (bumblebees), and Thunnini (tunas). The tribe Hominini is divided into subtribes by some scientists; subtribe Hominina then comprises "humans". The standard ending for the name of a zoological subtribe is "-ina". In botany, the standard ending for the name of a botanical tribe is "-eae". Examples include the tribes Acalypheae and Hyacintheae. The tribe Hyacintheae is divided into subtribes, including the subtribe Massoniinae. The standard ending for the name of a botanical subtribe is "-inae". In bacteriology, the form of tribe names is as in botany, e.g., Pseudomonadeae, based on the ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
