Profundulus guatemalensis, the Guatemalan killifish, is a species of killifish from the family Profundulidae which is found in Central America in Honduras, El Salvador, Belize and Guatemala. [1]
A killifish is any of various oviparous (egg-laying) cyprinodontiform fish. 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 2.5 to 5 centimetres, with the largest species growing to just under 15 centimetres (6 in).
Nothobranchius is a genus of small, freshwater killifish, classified in either the family Nothobranchiidae or a more inclusive Aplocheilidae in the order Cyprinodontiformes. There are many species: as of 2018 there are more than 70 species, many with very small distributions. They are primarily native to East Africa from Sudan to northern South Africa, but half a dozen species are found in the upper Congo River Basin and two species are from west-central Africa; the greatest species richness is in Tanzania.
Fundulus is a genus of ray-finned fishes in the superfamily Funduloidea, family Fundulidae. It belongs to the order of toothcarps (Cyprinodontiformes), and therein the large suborder Cyprinodontoidei. Most of its closest living relatives are egg-laying, with the notable exception of the splitfin livebearers (Goodeidae).
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 Popoyote, also known as the Chiapas killifish, is a killifish from the family Profundulidae which is endemic to the valley of San Cristobal de las Casas in the Chiapas Highlands in Southern Mexico. It is highly endangered because its natural habitat, which amounts to only a few square kilometers, is subject to contamination and urban sprawl from San Cristobal. It is currently being targeted by a civil society alliance for the protection of San Cristobal's wetlands.
The banded killifish is a North American species of temperate freshwater killifish belonging to the genus Fundulus of the family Fundulidae. Its natural geographic range extends from Newfoundland to South Carolina, and west to Minnesota, including the Great Lakes drainages. This species is the only freshwater killifish found in the northeastern United States. While it is primarily a freshwater species, it can occasionally be found in brackish water.
The spotted killifish is a small, short lived species of fish, an African rivuline from the family Nothobranchiidae. These fish are native to many isolated freshwater pools located in the savannah depressions of east Africa, specifically Malawi, Mozambique, Zimbabwe, and South Africa. This species of fish occurs in ephemeral waters and killifish eggs can survive long periods of dehydration. The word killifish likely comes from the Dutch kil for kill.
Nothobranchius kafuensis, known as the Caprivi killifish or Kafue killifish, is a species of killifish in the family Nothobranchiidae. This killifish is found in temporary pools, swamps and ditches in the floodplains of the Kafue and Upper Zambezi rivers in western Zambia and the Caprivi Strip in Namibia.
Guatemala, officially the Republic of Guatemala, is a country in Central America, bordered by Mexico to the north and west, Belize and the Caribbean to the northeast, Honduras to the east, El Salvador to the southeast and the Pacific Ocean to the south. With an estimated population of around 17.2 million, it is the most populous country in Central America and is the 11th most populous country in the Americas. Guatemala is a representative democracy; its capital and largest city is Nueva Guatemala de la Asunción, also known as Guatemala City, the largest city in Central America.
Heterandria is a genus of livebearing fishes within the family Poeciliidae. Most species occur in Guatemala and its surroundings, particularly Mexico, but the midget livebearer (H. formosa) comes from the southeastern United States.
Nothobranchius rachovii, or the bluefin notho, is a species of freshwater annual killifish from Mozambique. It can grow up to 6 cm (2.4"). It is popular among killifish enthusiasts, who raise them from eggs in aquaria.
Profundulus is a genus of fish in the family Profundulidae endemic to Mexico and northern Central America. According to many authorities, including Fishbase this is the only genus in the Profundulidae but workers have split the genus and raised a second genus Tlaloc.
Aphyosemion is a genus of African rivulines endemic as the name indicates to Africa. Many of these species are popular aquarium fish.
Profundulidae is a family of killifishes. The species of this family are native to Central America and Mexico.
The Gulf killifish is one of the largest members of the genus Fundulus; it is capable of growing up to 18 cm in length, whereas the majority of other Fundulus reach a maximum length of 10 cm. Therefore, F. grandis is among the largest minnows preyed upon by many sport fish, such as flounder, speckled trout, and red drum. Fundulus derives from the Latin meaning "bottom," and grandis means "large". The Gulf killifish is native to the Gulf of Mexico from Texas to Florida and the eastern coast of Florida and the Caribbean Sea in the Atlantic Ocean. Threats to the survival of the Gulf killifish include extreme changes in salinity, changes in temperatures, and toxic events such as the hypoxic dead zone in Louisiana and the Deepwater Horizon oil spill. The Gulf killifish is currently being used to test the effects of oil and oil dispersants on the physiology of marine species affected by these substances. This is significant to conservation biology, because with the continued extraction of oil and other natural resources from North American waters, it has become increasingly important to understand the risks and consequences in worst-case scenarios, such as the Deepwater Horizon oil spill, and the lasting effects on the marine ecosystem.

Cynodonichthys is a genus of freshwater killifish in the family Rivulidae. They are found in Middle America, ranging from southern Mexico, through Central America, to Colombia. They are non-annual killifish and inhabit small forest streams from the lowlands to an altitude of 1,500 m (4,900 ft).
The bayou killifish or bayou topminnow is a topminnow-like fish that thrives primarily in the shallow waters off the shores of the Americas, as well as fresh and brackish waters. Feeding off of small vertebrates and invertebrates, this fish displays reproduction techniques unique to its species.
Tlaloc is a genus of fish in the family Profundulidae endemic to Mexico, Guatemala and Honduras. The genus is not, however, recognised by Fishbase or in the 5th Edition of Fishes of the World. The genus is named for Tlaloc the water god of the Aztecs.
Alfaro huberi is a species of killifish, one of the livebearers in the family Poeciliidae, in the New World subfamily Poeciliinae. It is found in clear, fast flowing streams in Central America where it has been recorded from Honduras, Guatemala and Nicaragua. This fish was formally described in 1923 as Priapichthys huberi by Henry Weed Fowler with the type locality given as Marceligo Creek which is a tributary of the Río Tunky at Miranda in Nicaragua. The specific name honours the Curator of Mammals at the Academy of Natural Sciences of Philadelphia Wharton Huber (1877-1942), a colleague of Fowlers, who collected the type.
