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 introduced ...

Poeciliidae
Poeciliidae are a Family (biology), family of freshwater ray-finned fishes of the order Cyprinodontiformes, the tooth-carps, and include well-known live-bearing aquarium fish, such as the guppy, Poecilia, molly, Platy (fish), platy, and Green swordtail, swordtail. The original distribution of the family was the Southeastern United States to north of Río de la Plata, Argentina. Due to release of aquarium specimens and the widespread use of species of the genera ''Poecilia'' and ''Gambusia'' for mosquito control, though, introduced 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 All species in the Poecilidae are live-bearers. Differences are seen in the mode and degree of support the female gives the developing larvae. Many members of the family Poeciliidae are considered to be lecithotrophic (the mother prov ...

Sailfin Molly
The sailfin molly (''Poecilia latipinna'') is a livebearer fish typically found in both freshwater and brackish waterways along the East Coast of the United States, from North Carolina south to Florida, and around the Gulf of Mexico The Gulf of Mexico () is an oceanic basin and a marginal sea of the Atlantic Ocean, mostly surrounded by the North American continent. It is bounded on the northeast, north, and northwest by the Gulf Coast of the United States; on the southw ... to Texas, and south to the Yucatán Peninsula of Mexico. Given their preference for more brackish water conditions, mollies are often found within just a few yards or miles of the ocean, inhabiting coastal estuaries, lagoons, river deltas and swamps, as well as Tide, tidal areas (such as mangrove swamps) with a regular inflow of oceanic minerals and nutrients mixing with inland freshwater sources. Taxonomy The sailfin molly was originally described in 1821 as ''Mollienesia latipinna'' by the naturalist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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). Taxon named after him *The American halfbeak was named in his honor ''Hyporhamphus meeki'', as were: *the Mezquital pupfish (''Cyprinodon meeki'') *The firemouth cichlid (''Thorichthys 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, Pyrénées-Atlantiques, Pau then studied law in Madrid. He became a lawyer in Spain but was forced to leave due to his freethought, 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 Achille Valenciennes, 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. He also took part in the creation of the Academy of Science ...

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 genus ''Gambusia'' comes from the Cuban term, "Gambusino", which means "free-lance miner". 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 phylogenetic analysis published in 2015 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.
