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] |
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] |
Austrolebias
''Austrolebias'' is a genus of killifish in the family Rivulidae. These annual killifish live in temporary pools, swamps and streams in the Río de la Plata, Patos– Mirim and Mamoré basins in South America. Most species are small, less than in total length, but a few reach , making them some of the largest killifish (only a few ''Fundulus'', '' Moema'' and ''Orestias Orestias ( el, Ὀρεστιάς) was an ancient Greek settlement next to the Maritsa (or Evros) river, near or at the site of present-day Edirne, and close to the current border between Turkey and Greece.

Cynodonichthys
''Cynodonichthys'' is a genus of freshwater killifish in the family Rivulidae. They are found in Middle America, ranging from southern Mexico (north to Oaxaca and the Yucatán Peninsula), through Central America (where most species live), to Colombia (in the northwest and the Magdalena River basin).Vermeulen, F.B.M. (2013): Four new species of ''Rivulus'' Poey, 1860, subgenus ''Cynodonichthys'' Meek, 1904 (Teleostei: Cyprinodontiformes: Rivulidae) from the Magdalena River Basin, Central Colombia, including notes on ''Rivulus (Cynodonichthys) elegans'' Steindachner, 1880. ''Killi-Data Series, 2013: 42-63.'' They are non-annual killifish (similar to relatives such as ''Anablepsoides'', ''Atlantirivulus'', ''Laimosemion'' and ''Melanorivulus'') and inhabit small forest streams from the lowlands to an altitude of . They are small fish, up to in total length depending on the exact species. Species Until 2011, ''Cynodonichthys'' were included in ''Rivulus'', and some prefer to maint ...

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] |
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.

Leptolebias
''Leptolebias'' is a ray-finned fish genus of the killifish family Rivulidae. Like many of their relatives, they are rather ambiguously known as "pearlfish". They are endemic to the coastal areas of Brazil, where they inhabit ephemeral pools in tropical forests like the Mata Atlântica (or what remains thereof) and restinga. Rare and little-known, the entire genus seems to be close to extinction. Specifically, ''Leptolebias'' species have been found in two regions to date: between Maricá and Vila de Cava in Rio de Janeiro state, and between Itanhaém in southern São Paulo state and the Paranaguá bay catchment area in Paraná state. Description These small fishes measure only 2–3 cm (around one inch) in standard length. The females are colored uniformly brown, without darker markings, as are the females of some related killifishes. The males may have some dark pigmentation, but it does not extend into the distal dorsal fin, as it does in many related genera. Otherwis ...

Cynolebias
''Cynolebias'' is a genus of freshwater annual killifish in the family Rivulidae. They are endemic to northeastern Brazil, generally in temporary waters such as ponds in the Caatinga and adjacent regions. By far the highest species richness is in the São Francisco River basin, but there are also species east and north of this system, and west as far as the Tocantins River basin.Costa, W. J. E. M. (2014): Six new species of seasonal killifishes of the genus Cynolebias from the São Francisco river basin, Brazilian Caatinga, with notes on C. porosus (Cyprinodontiformes: Rivulidae). ''Ichthyological Exploration of Freshwaters, 25 (1): 79-96''. Many species have rather small distributions and some are highly threatened. They are small thickset fish, up to in total length depending on the exact species. Species The currently recognized species in this genus are: * '' Cynolebias albipunctatus'' W. J. E. M. Costa & G. C. Brasil, 1991 * '' Cynolebias altus'' W. J. E. M. Costa, 200 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aplocheiloidei
Aplocheiloidei is a suborder of the order Cyprinodontiformes consisting of three families which are commonly known as killifishes. Families The three families within the suborder Aplocheiloidei are: * Aplocheilidae Bleeker, 1859 * Nothobranchiidae Garman, 1895 * Rivulidae Myers, 1925 Proposed taxonomy Some authorities have lumped the three families into a single family, Aplocheilidae, a well-established name, chosen for its stability in usage over time, and to avoid the impact of a new name at the family rank for a popular aquarium fish group. Under this proposal, the Aplocheilidae includes three subfamilies: Aplocheilinae for the species from Asia, Madagascar and the Seychelles Seychelles (, ; ), officially the Republic of Seychelles (french: link=no, République des Seychelles; Creole: ''La Repiblik Sesel''), is an archipelagic state consisting of 115 islands in the Indian Ocean.

Campellolebias
''Campellolebias'' is a genus of killifish in the family Rivulidae from southeast Brazil. They are restricted to seasonal blackwater pools in forests in coastal parts of Santa Catarina and São Paulo states. They are small fish, up to in total length. Uniquely among killifish, ''Campellolebias'' and the closely related '' Cynopoecilus'' have internal fertilization. A part of the males' anal fin forms a "pseudo-gonopodium" that is used for inseminating the female. Species There are currently four recognized species in this genus: * '' Campellolebias brucei'' Vaz Ferreira & Sierra de Soriano, 1974 (Swordfin killifish) * '' Campellolebias chrysolineatus'' W. J. E. M. Costa, Lacerda & G. C. Brasil, 1989 * '' Campellolebias dorsimaculatus'' W. J. E. M. Costa, Lacerda & G. C. Brasil, 1989 * '' Campellolebias intermedius'' W. J. E. M.

Austrofundulus
''Austrofundulus'' is a genus of killifish in the family Rivulidae native to northern Colombia, northern Venezuela and southwestern Guyana. They are annual killifish where adults generally have a short life in temporary ponds or swamps and the eggs experience a period of drought, only hatching when again covered by water. They are small thickset fish, no more than in total length Fish measurement is the measuring of individual fish and various parts of their anatomies. These data are used in many areas of ichthyology, including taxonomy and fisheries biology. Overall length * Standard length (SL) is the length of a fish ..., and most less than half that size. Species ''Austrofundulus'' is closely related to '' Rachovia'', and it has been suggested that the former should be merged into the latter.

Aphyolebias
''Aphyolebias'' is a genus of New World killifish from the family Rivulidae. Although this genus is recognised by Fishbase In 1998, it was suggested that several species from the genus '' Moema'' be moved to the new ''Aphyolebias''. Genetic research has indicated that ''Moema'' is paraphyletic and monophyly is only established when it is merged with the genus ''Aphyolebias''. The Catalog of Fishes records ''Aphyolebias'' as a synonym of ''Moema''. Species The following species are classified as being in ''Aphyolebias'': *'' Aphyolebias boticarioi'' Costa, 2004 *'' Aphyolebias claudiae'' Costa, 2003 *'' Aphyolebias manuensis'' Costa, 2003 *'' Aphyolebias obliquus'' Costa, Sarimento & Barrera Barrera is a Spanish, Portuguese and Italian surname, meaning "barrier". .

Leptopanchax
''Leptopanchax'' is a genus of small fish, up to long, in the family Rivulidae. They are found in southeastern Brazil from Paraná to Rio de Janeiro.Costa, W.J.E.M. (2016)Comparative morphology and classification of South American cynopoeciline killifishes (Cyprinodontiformes: Aplocheilidae), with notes on family-group names used for aplocheiloids.''Vertebrate Zoology, 66 (2): 125-140.'' Depending on the exact species, they inhabit small seasonal channels in the Atlantic rainforest or temporary pools in open habitats. Several ''Leptopanchax'' species are very rare and '' L. sanguineus'' is possibly extinct. Species The species in ''Leptopanchax'' were formerly included in ''Leptolebias'', but this makes the latter genus paraphyletic, although they are still placed in that genus by Fishbase. There are currently 6 recognized species in ''Leptopanchax'': * ''Leptopanchax aureoguttatus'' ( da Cruz, 1974) * ''Leptopanchax citrinipinnis'' ( W. J. E. M. Costa, Lacerda & Tanizaki, ...
