CyprinodontiformesCyprinodontiformes () 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 superorderOstariophysi, while the toothcarps are Acanthopterygii.
AplocheilusAplocheilus is a genus of killifish in the familyAplocheilidae. Their native range is in South and Southeast Asia, from India to Vietnam and Malaysia, and from Nepal to Sri Lanka. Several species, especially the striped panchax, A. lineatus, are important aquarium fishes. EtymologyThe name Aplocheilus is composed of the Greek words aploe meaning "simplicity", and cheilos meaning "lip".
NothobranchiidaeNothobranchiidae are a family of bony fishes containing roughly 300 species, also known as African rivulines. They are small killifish, usually measuring about 5 centimetres (2.0 in). They are limited to Africa, living in fresh water but being also somewhat salt-tolerant. They are also found in muddy or brackish water. Some species are kept as aquarium pets. They have frilly fins and many are brightly colored.
PachypanchaxPachypanchax is a genus of aplocheilidkillifishes native to freshwater in Madagascar, with one species (P. playfairii) known from Seychelles.
Family (taxonomy)Family (Latin: familia, pl.: familiae) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus.
Fishes of the WorldFishes of the World is a standard reference for the systematics of fishes. It was first written in 1976 by the American ichthyologistJoseph S. Nelson (1937–2011). 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. The book begins with a general overview of ichthyology, although it is not self-contained.
FishA fish is an aquatic, anamniotic, gill-bearing vertebrateanimal with a tough cranium to protect the brain, but lacking limbs with digits. Fish can be grouped into the more basaljawless fish and the more common jawed fish, the latter including all livingcartilaginous and bony fish, as well as the extinct placoderms and acanthodians.
AsiaContinentAsia ( , UK also ) is the largest continent in the world by both land area and population. It covers an area of more than 44 million square kilometres, about 30% of Earth's total land area and 8% of Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilisations. Its 4.7 billion people constitute roughly 60% of the world's population.
RivulidaeThe Rivulidae are a family of killifishes in the orderCyprinodontiformes. 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.
MadagascarMadagascar, officially the Republic of Madagascar, is an island country in the Indian Ocean that includes the island of Madagascar and numerous smaller peripheral islands. Lying off the southeastern coast of Africa, it is the world's fourth-largest island, the second-largest island country, and the 46th-largest country overall. Its capital and largest city is Antananarivo.John McClelland (doctor)John McClelland or M'Clelland (1805 – 31 July 1883) was a British medical doctor with interests in natural history, who worked for the East India Company in India and Burma. He served as a temporary curator of the museum of the Asiatic Society of Bengal just before a permanent curator was found in Edward Blyth. McClelland is thought to have been born in Ireland, studied medicine and was admitted member of the Royal College of Surgeons in 1828.
SeychellesSeychelles ( , ; French: [sɛʃɛl] or [seʃɛl]), officially the Republic of Seychelles (French: République des Seychelles; Seychellois Creole: Repiblik Sesel), is an archipelagic country consisting of 115 islands in the Indian Ocean. Its capital and largest city, Victoria, is 1,500 kilometres (800 nautical miles) east of mainland Africa.
Order (taxonomy)Order (Latin: ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between family and class. Like the other ranks, orders reflect shared ancestry; for example, all owls belong to the order Strigiformes. In biological classification systems, orders and their usage are defined by nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order.*As an Amazon Associate I earn from qualifying purchases.
