Cyanobacteria are credited with the Great Oxidation Event that filled Earth's early atmosphere with oxygen roughly two and a half billion years ago.FactsCyanobacteriaConnectionsIn the Other AtlasesSourcesComments (0)Reader Challenges (0)FactsDisputedMember Species/Taxa CountScholarly debate8000 2Approximate described-species (or, for a genus, described-taxon) count; continually revised as species are newly described, reclassified or synonymized.Taxonomic RankWell-attestedPhylum / Division 2Scientific NameWell-attestedCyanobacteria 2ClassificationLiving or ExtinctWell-attestedYes 1CyanobacteriaFilter Results7 entriesCommon GroupAllMarine Cyanobacteria (2)Nostoc Family Cyanobacteria (Nostocaceae) (2)Toxin-Producing Planktonic Cyanobacteria (2)HabitatAllFreshwater (1)Marine (2)Conservation StatusAllNot Evaluated (2)Everyday GroupAllMarine Cyanobacteria (2)Nostoc Family Cyanobacteria (Nostocaceae) (2)Toxin-Producing Planktonic Cyanobacteria (2)DietAllPhotosynthetic Autotroph (7)System (Realm)AllFreshwater (3)Marine (4)Terrestrial (1)Relationship to PeopleAllEaten or Drunk by People (1)Ecotourism and Research (1)Farmed or Commercially Raised (1)Living or ExtinctAllYes (3)Where It LivesAllDenmark (1)Norway (2)Sweden (2)United States (1)Show ResultsBrowseCompareSelect all 7AnabaenaCyanobacteriaDolichospermum Flos-AquaeCyanobacteriaMicrocystis AeruginosaCyanobacteriaNostoc CommuneCyanobacteriaProchlorococcusCyanobacteriaSpirulinaCyanobacteriaTrichodesmium ErythraeumCyanobacteriaConnectionsChild Taxon OfBacteria, Taxa Well-attested Source Catalogue of LifeParent Taxon OfAnabaena, Species Well-attested Source GBIF Backbone Taxonomy: AnabaenaDolichospermum Flos-Aquae, Species Well-attested Source Wikidata: Dolichospermum Flos-AquaeMicrocystis Aeruginosa, Species Well-attested Source Wikidata: Microcystis AeruginosaNostoc Commune, Species Well-attested Source Wikidata: Nostoc CommuneProchlorococcus, Species Well-attested Source Wikidata: ProchlorococcusSpirulina, Species Well-attested Source GBIF Backbone Taxonomy: ArthrospiraTrichodesmium Erythraeum, Species Well-attested Source Wikidata: Trichodesmium ErythraeumIn the Other AtlasesFound InMexicoAlso in Geography Atlas: where this subject is found.The AntarcticAlso in Geography Atlas: where this subject is found.Sources1.
