Rivulus
''Rivulus'' is a genus of small freshwater fish in the Cyprinodontiformes family Rivulidae. It was traditionally considered to be the largest genus in its family; however, the genus's size is currently in dispute. Wilson J. E. Costa split this genus into several new genera (including ''Anablepsoides, Atlantirivulus, Cynodonichthys'', '' Kryptolebias'', ''Laimosemion'' and ''Melanorivulus'') in 2004 and 2011, leaving only a few Greater Antillean species in ''Rivulus'' itself. Despite being moved to other genera, some of the species retain the common name "rivulus", like the well-known mangrove rivulus (''Kryptolebias marmoratus''). Shortly after the review by Costa, another review authored by J.H. Huber refuted the split, moving the proposed genera back in ''Rivulus'' and again making the genus the largest in the family Aplocheilidae.Huber, J.H., 2012.

Mangrove Rivulus
The mangrove killifish or mangrove rivulus, ''Kryptolebias marmoratus'' (syn. ''Rivulus marmoratus''), is a species of killifish in the family Rivulidae. It lives in brackish and marine waters (less frequently in fresh water) along the coasts of Florida, through the Antilles, and along the eastern and northern Atlantic coasts of Mexico, Central America and South America (south to Brazil). It has a very wide tolerance of both salinity (0—68 ‰)Bester, CMangrove Rivulus.Florida Museum. Retrieved 6 May 2017. and temperature (),Hill, K Smithsonian Marine Station at Fort Pierce.

Anablepsoides
''Anablepsoides'' is a genus of killifish in the family Rivulidae native to tropical South America and the Lesser Antilles. The majority are from the Amazon and Orinoco basins, as well as freshwater systems in the Guiana Shield, but a few species are from northern Venezuela, northeastern Brazil (Tocantins River basin, as well as systems in Ceará and Maranhão) and the Lesser Antilles (Trinidad and Tobago, Grenada, Martinique and Margarita).Andrews, O. (2015). . The Online Guide to the Animals of Trinidad and Tobago Ecology. Retrieved 5 November 2018. Although largely restricted to lowlands, a few species occur in the lower East Andean foothills. They are mostly found in shallow fresh water swamps, streams, edges of rivers, ponds and pools, but a few may occur in brackish estuaries. They are able to jump over land and breathe air for short periods, allowing them to access isolated waters inhabited by few or no other fish. Several ''Anablepsoides'' species have small distributions a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Melanorivulus
''Melanorivulus'' is a genus of South American freshwater fish in the family Rivulidae. Most species are endemic to the Río de la Plata, eastern Amazon (west to Tapajós basin), Tocantins– Araguaia and São Francisco basins in Brazil, but a few members of this genus range west into Bolivia, south into Paraguay and Argentina, and east to Parnaíba and Sergipe in northeastern Brazil. Only ''M. schuncki'' occurs north of the Amazon River.Costa, W.J.E.M., Bragança, P.H.N. & Ottoni, F.P. (2015)A new miniature killifish of the genus ''Melanorivulus'' (Cyprinodontiformes: Rivulidae) from the coastal plains of north-eastern Brazil.''Vertebrate Zoology, 65 (1): 31–35.'' They inhabit shallow waters, generally deep, at the margins of streams in open or fairly open habitats like the Cerrado or Cerrado–Amazon transition. Many have tiny ranges and are seriously threatened.Costa, W.J.E.M. (2012)Two new species of ''Melanorivulus'' from the Caiapós hill, upper Araguaia river basin, Bra ...

''aqua, International Journal of Ichthyology, 18 (4): 181-190.'' Like their relatives, the adult ''Laimosemion'' often inhabit very small isolated waters, but they are not annual species like some other killifish. The adults can move some distance over land to find another water source. They do this by repeatedly flipping their body. They commonly complete their life cycle in the water, often laying their eggs among plant material. However, their eggs can survive several days of drought, only hatching when again covered by water.

Atlantirivulus
''Atlantirivulus'' is a genus of fishes in the family Rivulidae. They are endemic to shallow swamps, creeks, streams and pools in the Atlantic Forest in southeastern Brazil, ranging from Rio de Janeiro to Santa Catarina.Costa, W.J.E.M. (2014)Four new species of the genus ''Atlantirivulus'' (Cyprinodontiformes: Rivulidae) from the Brazilian Atlantic Forest. ''Vertebrate Zoology, 64 (1): 9–21.'' Several of the species are highly threatened, while others survive in well-protected reserves. ''A. janeiroensis'' was initially feared extinct, but has since been rediscovered in two reserves. Similar to closely related genera such as ''Anablepsoides'', ''Cynodonichthys'', ''Laimosemion'' and ''Melanorivulus'', ''Atlantirivulus'' are non-annual killifish. They are small fish, no more than in total length. Compared to many species in the family, the colors of ''Atlantirivulus'' are relatively dull.

Killifish
A killifish is any of various oviparous (egg-laying) cyprinodontiform fish (including families Aplocheilidae, Cyprinodontidae, Fundulidae, Profundulidae and Valenciidae). All together, there are 1,270 species of killifish, the biggest family being Rivulidae, containing more than 320 species. As an adaptation to living in ephemeral waters, the eggs of most killifish can survive periods of partial dehydration. Many of the species rely on such a diapause, since the eggs would not survive more than a few weeks if entirely submerged in water. The adults of some species, such as ''Kryptolebias marmoratus'', can additionally survive out of the water for several weeks. Most killies are small fish, from , with the largest species growing to just under . The word ''killifish'' is of uncertain origin, but is likely to have come from the Dutch ''kil'' for a kill (small stream). Although ''killifish'' is sometimes used as an English equivalent to the taxonomical term ''Cyprinodontidae'', s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rivulidae
The Rivulidae are a family of killifishes in the order Cyprinodontiformes. They are commonly known as rivulids, South American killifish or New World killifish. The latter names are slightly misleading, however, as they are neither restricted to South America – though most are in fact found there –, nor are they the only killifishes from the Americas. Occasionally, they are still referred to as rivulines, a term dating back to when they were considered a subfamily of the Aplocheilidae. The subfamilial name "Rivulinae" was already established for noctuid moths by Augustus Radcliffe Grote in 1895. That name, though it is the senior homonym, may be suppressed because the name Rivulinae for the fish subfamily is widespread, whereas the moth taxon is little used. The use of Rivulidae as the name for this family may need to be ruled in by the International Commission on Zoological Nomenclature. The alternative family-group name Cynolebiidae Hoedeman 1961 has been proposed a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Felipe Poey Y Aloy
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 ...
