Poeciliinae
Poeciliinae is a subfamily of killifish from the family Poeciliidae which contains species from the Americas which are collectively known as the livebearers because many, but not all, of the species within the subfamily are ovoviviparous. Characteristics All of the members of the subfamily Poeciliinae are ovoviviparous, i.e. they give birth to live young, except ''Tomereus'', with internal fertilisation and a large yolk in the egg. The males have the anterior rays, normally the third to fifth rays, in the anal fin elongated to form an intromittent organ called the gonopodium. Habitat and distribution The Poeciliinae are predominantly freshwater fish but some species live in brackish water, and some can even tolerate seawater. They are found in North America as far north as southern Canada, Central America and South America through to Patagonia. Some of the world's most popular aquarium fish such as guppies, swordtails and mollies are from this subfamily. They have been introd ...

Poeciliidae
The Poeciliidae are a family of freshwater fishes of the order Cyprinodontiformes, the tooth-carps, and include well-known live-bearing aquarium fish, such as the guppy, molly, platy, and swordtail. The original distribution of the family was the Southeastern United States to north of Río de la Plata, Argentina, and Africa, including Madagascar. Due to release of aquarium specimens and the widespread use of species of the genera ''Poecilia'' and ''Gambusia'' for mosquito control, though, poeciliids can today be found in all tropical and subtropical areas of the world. In addition, ''Poecilia'' and ''Gambusia'' specimens have been identified in hot springs pools as far north as Banff, Alberta. Live-bearing Although the whole family Poeciliidae is known as "live bearers" (viviparous), some species are egg-scattering with external fertilization. All African species are egg-layers, and (with the exception of the members of the genus ''Tomeurus''), all American species are live ...

Sailfin Molly
The sailfin molly (''Poecilia latipinna'') is a species of fish of the genus ''Poecilia''. They inhabit fresh, brackish, salt, and coastal waters from North Carolina to Texas and the Yucatán Peninsula of Mexico. Taxonomy The sailfin molly was originally described in 1821 as ''Mollienesia latipinna'' by the naturalist Charles Alexandre Lesueur, who based his description upon specimens from freshwater ponds in the vicinity of New Orleans, Louisiana. However, Lesueur described other collections of the sailfin molly as ''Mollienesia multilineata'' in 1821, the same year in which he described ''M. latipinna''. This conflict created confusion and eventually necessitated a ruling by the International Commission on Zoological Nomenclature (ICZN). In 1959, the ICZN placed precedence on the name ''Mollienesia latipinna'' Lesueur 1821. In a landmark definitive work on poeciliid fishes, Donn Rosen and Reeve Bailey (1959) noted the priority of ''Poecilia'' by Marcus Elieser Bloch and Johann ...

Seth Eugene Meek
Seth Eugene Meek (April 1, 1859, Hicksville, Ohio – July 6, 1914, Chicago) was an American ichthyologist at the Field Museum of Natural History in Chicago. He was the first compiler of a book on Mexican freshwater fishes. Together with his assistant, Samuel F. Hildebrand, he produced the first book on the freshwater fishes of Panama. He often collaborated with Charles H. Gilbert, and in 1884 on a collecting trip through the Ozarks, they discovered a new species, '' Etheostoma nianguae'', which only lives in the Osage River basin. Also with them on that excursion was David Starr Jordan, considered the father of modern ichthyology. After the Ozarks trip, Meek accepted the post of professor of biology and geology at Arkansas Industrial University (now the University of Arkansas). Tribute The American halfbeak was named in his honor ''Hyporhamphus meeki''.

Felipe Poey
Felipe Poey (May 26, 1799 – January 28, 1891) was a Cuban zoologist. Biography Poey was born in Havana, the son of French and Spanish parents. He spent several years (1804 to 1807) of his life in Pau then studied law in Madrid. He became a lawyer in Spain but was forced to leave due to his liberal ideas, returning to Cuba in 1823. He began to concentrate on the study of the natural science and traveled to France in 1825 with his wife. He began writing on the butterflies of Cuba and acquiring knowledge on fish, later supplying Georges Cuvier and Valenciennes with fish specimens from Cuba. He took part in the foundation, in 1832, of the Société Entomologique de France. Poey returned to Cuba in 1833 where he founded the Museum of Natural History in 1839. In 1842 he became the first professor of zoology and comparative anatomy at the University of Havana The University of Havana or (UH, ''Universidad de La Habana'') is a university located in the Vedado district of Hava ...

Gambusia
''Gambusia'' is a large genus of viviparous fish in the family Poeciliidae (order Cyprinodontiformes). ''Gambusia'' contains over 40 species, most of which are principally found in freshwater habitats, though some species may also be found in brackish or saltwater habitats. The type species is the Cuban gambusia, ''G. punctata''. The greatest species richness is in Mexico, Texas, and the Greater Antilles, but species are also found elsewhere in the eastern and southern United States, the Bahamas, Central America, and Colombia. ''Gambusia'' species are often called topminnows, or simply gambusias; they are also known as mosquitofish, which, however, refers more specifically to two species, '' G. affinis'' and '' G. holbrooki'', which are often introduced into ponds to eat mosquito larvae. As a consequence, they have been introduced widely outside their native range, and frequently become invasive, threatening local species. They are only occasionally kept in aquariums, due to thei ...

Brachyrhaphis
''Brachyrhaphis'' is a genus of poeciliids native to freshwater habitats in Central America. Most are restricted to Panama and Costa Rica, but ''B. holdridgei'' also occurs in Nicaragua and ''B. hartwegi'' is from Mexico and Guatemala. A recent phylogenetic analysis has suggested that ''Brachyrhaphis'' may not be of a monophyletic group. Species There are currently 12 recognized species in this genus: * ''Brachyrhaphis cascajalensis'' (Meek & Hildebrand, 1913) * ''Brachyrhaphis episcopi'' (Steindachner, 1878) * ''Brachyrhaphis hartwegi'' D.

Rudolf Kner
Rudolf Ignaz Kner (24 August 1810 – 27 October 1869) was an Austrian geologist, paleontologist, zoologist and ichthyologist. He also wrote some poems which were published by his brother-in-law K.A. Kaltenbrunner. Biography Kner was born in Linz where his father Johann Evangelist Georg Kner (1763-1845) was a tax officer. His mother Barbara (1770-1825), daughter of forester Johann von Adlersburg was earlier married to apothecary Felix Gulielmo until his death. Barbara had a daughter Marie Gulielmo from her earlier marriage before having Rudolf and his sister Pauline. Pauline Anna Barbara Kner (1809-1843) married the Austrian poet Karl Adam Kaltenbrunner (1804-1867) in 1834. Rudolf studied in the secondary school in Linz from 1818 and the high school from 1821. During this period he was encouraged in the natural sciences with a gift of minerals from his uncle Hallstatt Maximilian Kner (1755–1821). From 1823 he went to the Stiftsgymnasium Kremsmünster. His godfather, Ign ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theodore Nicholas Gill
Theodore Nicholas Gill (March 21, 1837 – September 25, 1914) was an American ichthyologist, mammalogist, malacologist and librarian. Career Born and educated in New York City under private tutors, Gill early showed interest in natural history. He was associated with J. Carson Brevoort in the arrangement of the latter's entomological and ichthyological collections before going to Washington D.C. in 1863 to work at the Smithsonian Institution. He catalogued mammals, fishes and mollusks most particularly although maintaining proficiency in other orders of animals. He was librarian at the Smithsonian and also senior assistant to the Library of Congress. He was elected as a member of the American Philosophical Society in 1867. Gill was professor of zoology at George Washington University. He was also a member of the Megatherium Club at the Smithsonian Institution in Washington, D.C.

Gambusiini
Gambusiini, also spelled Gambusini, is a tribe of killifishes from the "livebearer" family Poeciliidae. Their native range encompasses Central and much of North America, with a single species ''Gambusia lemaitrei'' occurring in South America. Some species have been widely introduced outside their native range and the Eastern mosquitofish ''Gambusia holbrooki'' is considered to be one of the 100 worst invasive species in the world and is responsible for declines in small native aquatic species worldwide. Genera The following general are classified in the tribe Gambusini: *Genus '' Belonesox'' Kner, 1860 *Genus ''Brachyrhaphis'' Regan, 1913 *Genus ''Gambusia'' Poey, 1854 *Genus ''Heterophallus ''Heterophallus'' is a genus of small poeciliids found near the coast in calm waters of river basins in southeastern Mexico.
