Haplotaxodon Microlepis
''Haplotaxodon microlepis'' is a species of fish in the family Cichlidae. It is endemic to Lake Tanganyika in Burundi, the Democratic Republic of the Congo, Tanzania, and Zambia. The adults spend most of their time in the open waters of the lake, either solitarily or in pairs. They sometimes form schools near the shores where there are rocky shorelines. They feed on zooplankton. Both parents mouthbrood the young until the attain a total length Fish measurement is the measuring of individual fish and various parts of their anatomies, for data used in many areas of ichthyology, including taxonomy and fishery biology.

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.

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] |
George Albert Boulenger
George Albert Boulenger (19 October 1858 – 23 November 1937) was a Belgian-British zoologist who described and gave scientific names to over 2,000 new animal species, chiefly fish, reptiles, and amphibians. Boulenger was also an active botanist during the last 30 years of his life, especially in the study of roses. Life Boulenger was born in Brussels, Belgium, the only son of Gustave Boulenger, a Belgian public notary, and Juliette Piérart, from Valenciennes. He graduated in 1876 from the Free University of Brussels (1834–1969), Free University of Brussels with a degree in natural sciences, and worked for a while at the Royal Belgian Institute of Natural Sciences, Brussels, as an assistant naturalist studying amphibians, reptiles, and fishes. He also made frequent visits during this time to the ''National Museum of Natural History (France), Muséum national d'Histoire naturelle'' in Paris and the Natural History Museum, London, British Museum in London.

Endemism
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...

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 ...

Tetsumi Takahashi
(23 February 1935 – 12 November 1990) was a Japanese avant-garde artist whose multidisciplinary practice included painting, performance, installation and sculpture. Associated with the Anti-Art (''Han-geijutsu'') movement in Japan in the late 1950s and early 1960s, Kudо̄'s provocative art was nourished by lifelong interests in science, sport and everyday objects. His work often presents a radically transformed and grotesque vision of the human body, calling into question its desires and its limits, as well as its future and origins. Never having officially identified with any one group or movement throughout his international career, the artist's body of work evades art historical classification. Biography Early life and education Kudо̄ was born in 1935 in Osaka, Japan to two artist parents, both art teachers. His father, painter Kudо̄ Masayoshi, passed away when Kudō was ten.Doryun Chung (ed.), ''Tetsumi Kudo: Garden of Metamorphosis'', exh. cat., Minneapolis, Walke ...

Kazuhiro Nakaya
is a Japanese marine scientist and Ichthyology, ichthyologist. He graduated from Hokkaido University with a BA in 1968 and with a PhD in 1972. He is professor of Marine Environment and Resources at the Marine Laboratory for Biodiversity. He specializes in taxonomy (biology), taxonomy and evolution of sharks, Rajiformes, rays, chimaeras, and Lake Tanganyikan fish. He is the author of many articles and books on sharks and fish.

Taxa Named By George Albert Boulenger
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. 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, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). 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 presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
