Cyprinodontiformes
Cyprinodontiformes is an order (biology), order of Actinopterygii, ray-finned fish, comprising mostly small, freshwater fish. Many popular aquarium fish, such as killifish and Poeciliidae, live-bearers, are included. They are closely related to the Atheriniformes and are occasionally included with them. A colloquial term for the order as a whole is toothcarps, though they are not actually close relatives of the true carps – the latter belong to the superorder Ostariophysi, while the toothcarps are Acanthopterygii. The families of Cyprinodontiformes can be informally divided into three groups based on reproductive strategy: Viviparity, viviparous and Ovoviviparity, ovoviviparous (all species give live birth), and Oviparity, oviparous (all species are egg-laying). The live-bearing groups differ in whether the young are carried to term within (ovoviviparous) or without (viviparous) an enclosing eggshell.

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.

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 ...

Aplocheilidae
Aplocheilidae, the Asian killifishes or Asian rivulines, is a family of fish in the order Cyprinodontiformes found in Asia. Some authorities use this family-group name, which is well-established, for a single lumped aplocheiloid family as it gives the nomenclature stability over time and avoids the impact of a new name at family rank for a popular aquarium fish group.van der Laan, R., Eschmeyer, W.N. & Fricke, R. (2014)Family-group names of Recent fishes.''Zootaxa, 3882 (2): 1–230.'' Following this proposal, Aplocheilidae would include three subfamilies: Aplocheilinae for the species from Asia, Madagascar and the Seychelles; Cynolebiinae (formerly called Rivulidae) for the species from the Americas; and Nothobranchiinae for the species from the African mainland.Costa, W.J.E.M.

Cyprinodontoidea
Pupfish are a group of small killifish belonging to ten genera of the family Cyprinodontidae of ray-finned fish. Pupfish are especially noted for being found in extreme and isolated situations. They are primarily found in North America, South America, and the Caribbean region, but ''Aphanius'' species are from southwestern Asia, northern Africa, and southern Europe. As of August 2006, 120 nominal species and 9 subspecies were known. Several pupfish species are extinct and most extant species are listed. In the U.S., the most well-known pupfish species may be the Devil's Hole Desert Pupfish, native to Devil's Hole on the Nevada side of Death Valley National Park. Since 1995 the Devil's Hole Pupfish has been in a nearly steady decline, where it was close to extinction at 35–68 fish in 2013. The common name is said to derive from the mating habits of the males, whose activities vaguely resemble puppies at play. Carl L. Hubbs, a prominent ichthyologist and one of the first peopl ...

Acanthopterygii
Acanthopterygii (meaning "spiny finned one") is a superorder of bony fishes in the class Actinopterygii. Members of this superorder are sometimes called ray-finned fishes for the characteristic sharp, bony rays in their fins; however this name is often given to the class Actinopterygii as a whole. Taxonomy The superorder Acanthopterygii contains the following orders: * Series Berycida ** Order Beryciformes, alfonsinos, whalefishes and pricklefishes ** Order Trachichthyiformes, pinecone fishes and slimeheads or roughies ** Holocentriformes, soldier fishes and squirrel fishes * Series Percomorpha ** Subseries Ophidiida *** Order Ophidiiformes, cusk-eels ** Subseries Batrachoidida *** Order Batrachoidiformes, toadfishes ** Subseries Gobiida *** Order Kurtiformes, nurseryfishes and cardinalfishes *** Order Gobiiformes, gobies **Subseries Ovalentaria *** Order Mugiliformes, the mullets *** Order Cichliformes, cichlids *** Order Blenniiformes, blennies *** Order Gobiesocif ...

Atheriniformes
The Atheriniformes, also known as the silversides, are an order (biology), order of ray-finned fishes that includes the Atherinidae, Old World silversides and several less-familiar families, including the unusual Phallostethidae. The order includes at least 354 species. They are found worldwide in tropical and temperate marine and freshwater environments. Description Atheriniformes are generally elongated and silvery in colour, although exceptions do exist. They are typically small fish, with the largest being the Odontesthes bonariensis, Argentinian silverside, with a head-body length of , and the smallest species, such as the Bangkok minnow, being only in adult length. Members of the order usually have two dorsal fins, the first with flexible spines, and an anal fin with one spine at the front. The lateral line is typically weak or absent. Atheriniform larvae share several characteristics; the gut is unusually short, a single row of melanophores occurs along the back, and t ...

Anableps Dowei
The Pacific four-eyed fish (''Anableps dowei)'' is a species of four-eyed fish native to the coastal waters on the Pacific side of southern Mexico to Nicaragua. This fish is gregarious and inhabits mangrove swamps, tidal mudflats, and other coastal brackish ecosystems. During low tide, they will crawl onto shore to eat algae and other organic matter. This species has female biased sexual dimorphism, with males growing to 22 cm (8.7 in) TL while females can grow up to 34 cm (13.4 in) TL. The male also has a prominent gonopodium used to impregnate females during mating. As with other members of Anablepinae, this species is livebearing and has left or right leaning genitals to prevent inbreeding Inbreeding is the production of offspring from the mating or breeding of individuals or organisms that are closely related genetically. By analogy, the term is used in human reproduction, but more commonly refers to the genetic disorders and o .... The name "four-eyed fish" comes f ...

Fundulopanchax Scheeli
The emerald aphyosemion (''Fundulopanchax scheeli'') is a species of killifish, endemic to the lower Cross River basin in Nigeria. It is a coastal rainforest fish which lives in small streams and ponds. It prefers a temperature of around , and a slightly acidic pH around 6–7. The specific name honours the Danish count, army colonel, explorer and ichthyologist Ichthyology is the branch of zoology devoted to the study of fish, including bony fish ( Osteichthyes), cartilaginous fish (Chondrichthyes), and jawless fish (Agnatha).

Mummichog
The mummichog (''Fundulus heteroclitus'') is a small killifish found along the Atlantic coast of the United States and Canada. Also known as Atlantic killifish, mummies, gudgeons, and mud minnows, these fish inhabit brackish and coastal waters including estuaries and salt marshes. The species is noted for its hardiness and ability to tolerate highly variable salinity, temperature fluctuations from , very low oxygen levels (down to 1 mg/L), and heavily polluted ecosystems. As a result, the mummichog is a popular research subject in embryological, physiological, and toxicological studies. It is also the first fish ever sent to space, aboard Skylab in 1973. Taxonomy The genus name ''Fundulus'' comes from ', meaning bottom, from the fish's habit of swimming near muddy bottoms. The species name ''heteroclitus'' means irregular or unusual. The type specimen was first described by Carl Linnaeus in 1766, from near Charleston, South Carolina. Other scientific names now considered syno ...

Actinopterygii
Actinopterygii (; ), members of which are known as ray-finned fishes, is a class of bony fish. They comprise over 50% of living vertebrate species. The ray-finned fishes are so called because their fins are webs of skin supported by bony or horny spines (rays), as opposed to the fleshy, lobed fins that characterize the class Sarcopterygii (lobe-finned fish). These actinopterygian fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the link or connection between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). By species count, actinopterygians dominate the vertebrates, and they constitute nearly 99% of the over 30,000 species of fish. They are ubiquitous throughout freshwater and marine environments from the deep sea to the highest mountain streams. Extant species can range in size from ''Paedocypris'', at , to the massive ocean sunfish, at , and the long-bodied oarfish, at . The vast majority of Actinopt ...
