Cyprinodontiformes is an order of ray-finned fish, comprising mostly small, freshwater fish. Many popular aquarium fish, such as killifish and 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.
Anatolichthys anatoliae, the Anatolian giant killifish or Lake Tuz toothcarp, is a species of fish in the family Aphaniidae. It is endemic to Turkey. It is known from freshwater springs and streams around Lake Tuz, as well as from the Lake Beyşehir basin and from Konya eastward to Niğde. It lives in clear, well-oxygenated running freshwaters. It is threatened by water abstraction and the drying out of streams and springs. It is also impacted by the introduction of Gambusia species.
Aphanius, commonly referred to as Mediterranean killifish, is a genus of the order Cyprinodontiformes in the family Aphaniidae. They are found in fresh and brackish waters in the coastal plains of the Mediterranean region.
Anatolichthys sureyanus, the Burdur toothcarp or Sureyan killifish, is a species of freshwater fish in the family Aphaniidae.
The scaleless killifish or Hazar toothcarp is a species of freshwater fish in the family Aphaniidae. It is the only species in its genus, and is endemic to Lake Hazar in Turkey. It is a pelagic species that comes to shore in spring–early summer to spawn. It is threatened by the falling water levels of Lake Hazar due to water abstraction and reduced rainfall due to climate change.
Leptolebias is a ray-finned fish genus of the killifish family Rivulidae. Like many of their relatives, they are rather ambiguously known as "pearlfish".
Valencia letourneuxi, the Corfu toothcarp, is a species of fish in the family Valenciidae. It is found in Albania and Greece. Its natural habitats are rivers, freshwater marshes, freshwater spring, and coastal saline lagoons. It is threatened by habitat loss. The specific name of this fish honours the collector of the type, the botanist Aristide-Horace Letourneux (1820-1890). The species was described as Fundulus letourneuxi in 1880 by Henri Émile Sauvage with a type locality of Cressida, Corfu. It also formerly occurred on the island of Lefkas but is now considered to be extirpated from both there and Corfu. Valencia letourneuxi is a highly endangered freshwater species that faces threats from habitat degradation, water abstraction, and foreign species. While little is known of its ecological history, V. Letourneuxi produce 2.2 mm eggs during the spring on aquatic plants in stagnant water that has a lot of vegetation.
The pike topminnow, more commonly known as pike killifish and sometimes referred to as topminnow, is a species of poeciliid found from Mexico to Nicaragua. It has also been introduced to Florida, USA. It is the only known member of its genus. The pike topminnow was described in 1860 by Austrian ichthyologist Rudolf Kner, who gave the type locality as Belize, which is reflected in this species' specific name.
Rachovia is a genus of killifish from the family Rivulidae the species of which are endemic to the Orinoco, Maracaibo and Magdalena basins in Colombia and Venezuela, where they live in small temporary waters like ponds. They are small annual killifish that reach up to 6 cm (2.4 in) in total length. The name of this genus honours the German aquarist Arthur Rachow (1884–1960) who sent fish specimens to George S. Myers.
Anatolichthys danfordii, the Kızılırmak toothcarp or Sultan Sazlığı toothcarp, is a species of killifish belonging to the family Aphaniidae. It is endemic to the Kızılırmak River and the upper Seyhan River drainage systems and is now restricted to a few locations in the Sultan Sazlığı marshes. Though little data is available, the population of the fish seems to be declining. The International Union for Conservation of Nature has rated its conservation status as being "critically endangered" and fears it may become extinct in the wild if the drainage of the marshes continues.
The Arabian toothcarp, known also as the Arabian toothcarp or mother-of-Pearl fish is a species of killifish belonging to the family Aphaniidae. It can be found from the shores of the Red Sea south to Ethiopia, the Gulf of Aden, the Arabian Sea and along the Persian Gulf east to Pakistan and India. It is also found in the Suez Canal, the northern coast of the Sinai Peninsula, and in one location on the Palestinian coast. The former recognized subspecies: A. d. richardsoni, the Dead Sea toothcarp endemic to the Dead Sea has now been raised to a full species as Aphaniops richardsoni.
Valencia robertae is a species of Mediterranean killifish, from the family Valenciidae. It is endemic to Greece where it is found in the Lower Pinios and lower Mornos Rivers in Greece. The species was described in 2004 with the type locality given as River Pinios south of Kavasila. The specific name honours the Italian ichthyologist Roberta Barbieri of the Hellenic Centre for Marine Research in Athens.
Procatopodinae is a subfamily of the family Poeciliidae, the "livebearers", in the order Cyprinodontiformes. Some authorities treat this subfamily as a family, the Procatopodidae, including the banded lampeye.
The Procatopodini is an African tribe of fishes, it is part of the subfamily Procatopodinae, within the family Poeciliidae.
The Farsi toothcarp is a species of pupfish belonging to the family Aphaniidae. It is endemic to the Maharloo Lake Basin in Iran, residing in springs, lagoons, and marshes containing fresh to brackish water.
Apricaphanius is a genus of killifishes in the family Aphaniidae, which are native to northern Africa and southern Europe. All species in the genus have very small distributions and are seriously threatened.
Esmaeilius is a genus of toothcarps in the family Aphaniidae. They are native to Iran and one species extending to Iraq. Most species in the genus have very small distributions and all are seriously threatened.
Paraphanius is a genus of killifishes in the family Aphaniidae, which are native to western Asia. Several species in the genus have very limited distribution and may be threatened.
Anatolichthys is a genus of toothcarps in the family Aphaniidae, which are native to Asia Minor. Several species in the genus have very limited distribution and may be threatened.
Aphaniops is a genus of killifishes in the family Aphaniidae, which are native to Western Asia, Northeast Africa and east to southwest India. Several species in the genus have very limited distribution and may be threatened.
