The order is closely related to, and sometimes combined with, the Atheriniformes; its members are colloquially called toothcarps, though they are not close relatives of the true carps, which belong to the separate superorder Ostariophysi.FactsCyprinodontiformesConnectionsIn the Other AtlasesSourcesComments (0)Reader Challenges (0)FactsClassificationLiving or ExtinctWell-attestedYes 1Taxonomic RankWell-attestedOrder 2CyprinodontiformesFilter Results5 entriesCommon GroupAllOther Bony Fish (5)HabitatAllDesert (1)Freshwater (1)Lake (1)River (1)Vernal Pool (1)Conservation StatusAllExtinct (1)Least Concern (3)Vulnerable (1)EcosystemAllLake Tanganyika (1)Mojave Desert (1)Everyday GroupAllOther Bony Fish (5)DietAllCarnivore (1)Omnivore (2)System (Realm)AllFreshwater (4)Terrestrial and Freshwater (1)Relationship to PeopleAllHunted or Fished (2)Invasive or Introduced Species (1)Kept as Pets (2)Living or ExtinctAllYes (5)Where It LivesAllAfrica (3)Mozambique (2)North America (2)Rwanda (1)South Africa (1)Zimbabwe (2)Show ResultsBrowseCompareSelect all 5Amargosa River pupfishCyprinodontiformesNothobranchius furzeriCyprinodontiformesNothobranchius rachoviiCyprinodontiformesTanganyika KillifishCyprinodontiformesTecopa pupfishCyprinodontiformesConnectionsParent Taxon OfAmargosa River pupfish, Species Well-attested Source Wikidata: Amargosa River pupfishNothobranchius furzeri, Species Well-attested Source Nothobranchius furzeri (Wikidata)tier 2Nothobranchius rachovii, Species Well-attested Source Nothobranchius rachovii (Wikidata)tier 2Tanganyika Killifish, Species Well-attested Source Tanganyika Killifish (Wikidata)tier 2Tecopa pupfish, Species Well-attested Source Wikidata: Tecopa pupfishIn the Other AtlasesFound InArgentinaAlso in Geography Atlas: where this subject is found.Sources1.
