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)FactsTaxonomic RankWell-attestedOrder 2Member Count BandWell-attestedOver 1000 Species 3Era First AppearedWell-attestedCretaceous 4ClassificationLiving or ExtinctWell-attestedYes 1CyprinodontiformesFilter Results5 entriesCommon GroupAllOther Bony Fish (5)Everyday GroupAllOther Bony Fish (5)HabitatAllDesert (1)Freshwater (1)Lake (1)River (1)Vernal Pool (1)Where It LivesAllAfrica (3)Mozambique (2)North America (2)Rwanda (1)South Africa (1)Zimbabwe (2)Conservation StatusAllExtinct (1)Least Concern (3)Vulnerable (1)DietAllCarnivore (1)Omnivore (2)System (Realm)AllFreshwater (4)Terrestrial and Freshwater (1)Living or ExtinctAllYes (5)Relationship to PeopleAllHunted or Fished (2)Invasive or Introduced Species (1)Kept as Pets (2)CITES AppendixAllNot Listed (3)NatureServe RankAllG1 Critically Imperiled (1)GX Presumed Extinct (1)EcosystemAllLake Tanganyika (1)Mojave Desert (1)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 2Pachypanchax sparksorum, Species Well-attested Source FishBase: Pachypanchax sparksorum (FishBase)Tanganyika 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.
