Chalinochromis Popelini
''Chalinochromis'' is a small cichlid genus from the subfamily Pseudocrenilabrinae. These ray-finned fishes are endemic to Lake Tanganyika in the East African Rift. The scientific name refers to the bridle-like markings across the heads of members of this genus. They have specialized jaws enabling them to feed on sponges.

Max Poll
Max Fernand Leon Poll (21 July 1908 in Ruisbroek, Flemish Brabant, Ruisbroek – 13 March 1991 in Uccle) was a Belgians, Belgian ichthyologist who specialised in the Cichlidae. In the years 1946 and 1947 he organised an exploration, 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 Université Libre de Bruxelles, and Conservator (museum), conservator at Musée Royal du Congo Belge in Tervuren. He was an honorary member of the American Society of Ichthyologists and Herpetologists.

Sven O
Sven (in Danish and Norwegian, also Svend and also in Norwegian most commonly Svein) is a Scandinavian first name which is also used in the Low Countries and German-speaking countries. The name itself is Old Norse for "young man" or "young warrior". The original spelling in Old Norse was ''sveinn''. Over the centuries, many northern European rulers have carried the name including Sweyn I of Denmark (Sven Gabelbart). An old legend relates the pagan king Blot-Sven ordered the execution of the Anglo-Saxon monk Saint Eskil. In medieval Swedish, "sven" (or "sven av vapen" (sven of arms)) is a term for squire. The female equivalent, Svenja, though seemingly Dutch and Scandinavian, is not common anywhere outside of German-speaking countries. Sven can also be spelled with W, Swen, but is pronounced as Sven. The Icelandic version of Sven/Svend is Sveinn (); the Faroese version is Sveinur (). Entertainment and music * Sven Einar Englund, Finnish composer * Sven Epiney, Swiss televis ...

Chalinochromis Brichardi
''Chalinochromis brichardi'' is a species of fish in the family Cichlidae. It is found in Burundi, the Democratic Republic of the Congo, Tanzania, and Zambia Zambia (), officially the Republic of Zambia, is a landlocked country at the crossroads of Central, Southern and East Africa, although it is typically referred to as being in Southern Africa at its most central point. Its neighbours are t .... It is endemic to Lake Tanganyika. It builds a nest of rubble which is hidden by plants or algae, and its diet consists primarily of invertebrates. The specific name of this fish honours the fish dealer Pierre Brichard (1921-1990), who was the collector of the type. Description Adult specimens average a length of approximately 8.9 cm (3.5 inches), but larger specimens up to 14 cm (5.5 inches) have been recorded in captivity. ''C. brichardi'' lacks any body striping as an adult, only possessing barring around the facial region, which differentiates it from other ''Chalino ...

Lamprologini
Lamprologini is a tribe of African cichlid fishes. It contains seven genera and nearly 100 species. Over half of the species in this tribe are in the large genus ''Neolamprologus''. Most genera in the tribe are endemic to Lake Tanganyika, but one species of ''Neolamprologus'' ('' N. devosi'') is from the Malagarasi River in Tanzania, and several species of ''Lamprologus'' are from the Congo River Basin. The species in this tribe are very small to medium-sized cichlids, but vary extensively in appearance and habitat preference.Smith, M.P. (1998). Lake Tanganyikan Cichlids, p. 10—11. Unlike most Tanganyika cichlids which are mouthbrooders, Lamprologini species are substrate spawners (typically using caves or rock crevices), and some are shell dwellers. Genera * ''Altolamprologus'' (3 species) * ''Chalinochromis'' (3 species) * ''Julidochromis'' (6 species) * ''Lamprologus'' (19 species) * ''Lepidiolamprologus'' (6-11 species) * ''Neolamprologus'' (~50 species) * ''Telmatochro ...

Aquarium
An aquarium (plural: ''aquariums'' or ''aquaria'') is a vivarium of any size having at least one transparent side in which aquatic plants or animals are kept and displayed. Fishkeepers use aquaria to keep fish, invertebrates, amphibians, aquatic reptiles, such as turtles, and aquatic plants. The term ''aquarium'', coined by English naturalist Philip Henry Gosse, combines the Latin root , meaning 'water', with the suffix , meaning 'a place for relating to'. The aquarium principle was fully developed in 1850 by the chemist Robert Warington, who explained that plants added to water in a container would give off enough oxygen to support animals, so long as the numbers of animals did not grow too large. The aquarium craze was launched in early Victorian England by Gosse, who created and stocked the first public aquarium at the London Zoo in 1853, and published the first manual, ''The Aquarium: An Unveiling of the Wonders of the Deep Sea'' in 1854.Katherine C.

Monophyletic
In cladistics for a group of organisms, monophyly is the condition of being a clade—that is, a group of taxa composed only of a common ancestor (or more precisely an ancestral population) and all of its lineal descendants. Monophyletic groups are typically characterised by shared derived characteristics ( synapomorphies), which distinguish organisms in the clade from other organisms. An equivalent term is holophyly. The word "mono-phyly" means "one-tribe" in Greek. Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic group'' consists of all of the descendants of a common ancestor minus one or more monophyletic groups. A '' polyphyletic group'' is characterized by convergent features or habits of scientific interest (for example, night-active primates, fruit trees, aquatic insects). The features by which a polyphyletic group is differentiated from others are not inherited from a common ancestor. These definitions have tak ...

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Telmatochromis
__NOTOC__ ''Telmatochromis'' is a small cichlid genus of the subfamily Pseudocrenilabrinae. These ray-finned fishes are endemic to the Lake Tanganyika basin (mostly in the lake itself, but also its outflow river Lukuga) in Africa. Systematics Analysis of their mtDNA NADH dehydrogenase subunit 2 (ND2) sequence shows that hybridization must have played some role in the evolution of this genus. (2007): Phylogenetic relationships of the Lake Tanganyika cichlid tribe Lamprologini: The story from mitochondrial DNA. '' Mol. Phylogenet. Evol.'' 45(2): 629–642. (HTML abstract) For one thing, it might be that ''Telmatochromis'' is close to ''Julidochromis'', which they somewhat resemble. A possibility is hybridization between the ancestor of ''Telmatochromis'' and a lineage of ''Julidochromis'' which later gave rise to '' J. marlieri'' and the Convict Julie (''J. regani''). Similar ND2 DNA has been found in these and '' T. bifrenatus'', '' T. brichardi'' and '' T. temporalis''. '' T. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Julidochromis Regani
The convict julie (''Julidochromis regani'') is a cichlid species in the subfamily Pseudocrenilabrinae family endemic to Lake Tanganyika. Hence it is found in Burundi, the Democratic Republic of the Congo, Tanzania, and Zambia. The fish is named after Charles Tate Regan. This species is closely related to '' Julidochromis marlieri''. Possibly, a male common ancestor of these two hybridised with some female ''Telmatochromis'' ancestor in their evolutionary past. (2007): Phylogenetic relationships of the Lake Tanganyika cichlid tribe Lamprologini: The story from mitochondrial DNA. '' Mol. Phylogenet. Evol.'' 45(2): 629–642. (HTML abstract) Description ''Julidochromis regani'' is a small (up to TL) ray-finned fish. Its pale to golden yellow body is slender and elongated. A varying black stripe pattern, depending on which part of the lake the fish originates from, is present. However, ''Julidochromis regani'' all have four slender lateral black stripes that run the length of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
