The Heterandriini is a tribe of killifishes from the "livebearer" family Poeciliidae, consisting of seven genera and around 50 species. [2] The tribe was originally delineated by Carl Leavitt Hubbs in 1924. [3]
The genera classified in this tribe are: [2]
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.
The Serranidae are a large family of fishes belonging to the order Perciformes. The family contains about 450 species in 65 genera, including the sea basses and the groupers. Although many species are small, in some cases less than 10 cm (3.9 in), the giant grouper is one of the largest bony fishes in the world, growing to 2.7 m in length and 400 kg (880 lb) in weight. Representatives of this group live in tropical and subtropical seas worldwide.
Fishes of the World by Joseph S. Nelson is a standard reference for fish systematics. Now in its fifth edition (2016), the work is a comprehensive overview of the diversity and classification of the 30,000-plus fish species known to science.
Grenadiers or rattails are generally large, brown to black gadiform marine fish of the subfamily Macrourinae, the largest subfamily of the family Macrouridae. Found at great depths from the Arctic to Antarctic, members of this subfamily are amongst the most abundant of the deep-sea fish.
Gambusia is a large genus of viviparous fish in the family Poeciliidae. Gambusia contains over 40 species, most of which are principally found in freshwater habitats, though some species may also be found in brackish or saltwater habitats. The type species is the Cuban gambusia, G. punctata. The greatest species richness is in Mexico, Texas, and the Greater Antilles, but species are also found elsewhere in the eastern and southern United States, the Bahamas, Central America, and Colombia. Gambusia species are often called topminnows, or simply gambusias; they are also known as mosquitofish, which, however, refers more specifically to two species, G. affinis and G. holbrooki, which are often introduced into ponds to eat mosquito larvae. As a consequence, they have been introduced widely outside their native range, and frequently become invasive, threatening local species. They are only occasionally kept in aquariums, due to their relative lack of color and the highly aggressive nature of the aforementioned mosquitofish species.
The rainbowfish are a family, Melanotaeniidae, of small, colourful, freshwater fish found in northern and eastern Australia, New Guinea, islands in Cenderawasih Bay and Raja Ampat Islands in Indonesia, and in Madagascar.
Rasbora is a genus of fish in the family Cyprinidae. They are native to freshwater habitats in South and Southeast Asia, as well as southeast China. A single species, R. gerlachi, is only known from an old specimen that reputedly originated from Africa (Cameroon), but this locality is considered doubtful. They are small, up to 17 cm (6.7 in) long, although most species do not surpass 10 cm (4 in) and many have a dark horizontal stripe.
Scleromystax is a genus of fish in the family Callichthyidae endemic to small tributaries from several coastal river basins draining the southern and southeastern regions in Brazil. Most of the species of Scleromystax are highly sexually dimorphic; males have developed odontodes inserted in fleshy papillae on the preopercular-opercular region and the dorsal and pectoral fins are 2–3 times as long as those of females. S. salmacis is an exception, as its sexually dimorphic features are subtle and non-remarkable.
Heroini is a fish tribe from the Cichlasomatinae subfamily in the cichlid family. All cichlids native to the Greater Antilles, United States, Mexico and northern Central America are members of this tribe. It also includes most cichlid species in southern Central America and several species from South America. A large percentage of its species were formerly placed in the genus Cichlasoma, but have since been moved to other genera.
Goodeinae is a subfamily of splitfins from Mexico, part of the family Goodeidae. They are small fish which mostly live in fresh water, especially around Mesa Central, west of Mexico City. Members of the subfamily are also found in brackish water on both the east and west coasts. They typically have small ranges and many are seriously threatened. The subfamily takes its name from its type genus Goodea and so is ultimately named after the American ichthyologist George Brown Goode (1851-1896).
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).
Poeciliinae is a subfamily of killifish from the family Poeciliidae which contains species from the Americas which are collectively known as the livebearers because many, but not all, of the species within the subfamily are ovoviviparous.
Atherinopsinae is a subfamily of the Neotropical silversides, part of the family Atherinopsidae. This subfamily is made up of two tribes, six genera and around 30 species. They are found in the eastern Pacific and south-western Atlantic and the subfamily contains marine, brackish and freshwater species.
Phallostethinae is a subfamily of fishes, one of two subfamilies in the family Phallostethidae, the priapumfishes. The species in this subfamily are characterised mainly by having highly protrusible jaws. The genus Neostethus appears to be the sister taxon to the other two genera in the subfamily. The species in the Phallostethinae are found in south-east Asia, the Malay Archipelago and the Philippines.
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 Poeciliini is a tribe of killifishes from the "livebearer" family Poeciliidae, consisting of six genera and just over 100 species.
The Girardini is a tribe of killifishes from the "livebearer" family Poeciliidae, consisting of three genera and 10 species. The tribe was originally delineated by Carl Leavitt Hubbs in 1924.
Cnesterodontini is a tribe of fishes which are within the subfamily Poeciliinae of the family Poeciliidae. This tribe is distinguished from other tribes in the Poeciliinae by the males having five rays in the pelvic fin, there is a pedicle at the base of the third ray which joins it to the fourth ray, another pedicle at the third rays tip and a membrane there too.
Naucratinae is a subfamily of ray-finned fish from the family Carangidae which consists of five genera and 13 species.
