Home›Mollusks›Conservation Status›EndangeredBrowse ByEndangeredConservation status groups species by how close each one is to extinction, using the category scale most conservation scientists rely on, running from least concern through near threatened, vulnerable, endangered and critically endangered, to extinct in the wild or extinct. Assessments come from bodies such as the IUCN Red List and are re-checked as a species population changes. A species with no current assessment recorded here is not shown as any of these categories.FactsEndangeredSourcesComments (0)Reader Challenges (0)FactsComparisonReproductive ModeWell-attestedOviparous (Egg-Laying) 1EndangeredFilter Results3 entriesCommon GroupAllBivalves (Clams, Mussels, Oysters) (1)Gastropods (Snails And Slugs) (2)Everyday GroupAllBivalves (Clams, Mussels, Oysters) (1)Gastropods (Snails And Slugs) (2)HabitatAllFreshwater (1)Neritic Zone (1)Where It LivesAllCanada (1)China (1)Denmark (1)Ireland (1)North America (2)Norway (1)Sweden (1)United States (1)DietAllFilter Feeder (1)Herbivore (1)System (Realm)AllFreshwater (1)Marine (1)Terrestrial (1)Living or ExtinctAllYes (3)Relationship to PeopleAllHunted or Fished (2)CITES AppendixAllNot Listed (3)NatureServe RankAllG1 Critically Imperiled (1)G4 Apparently Secure (1)TaxonomyAllBivalvia (1)Gastropoda (1)Haliotis (1)Show ResultsBrowseCompareSelect all 3Discus macclintockiEndangeredFreshwater Pearl Mussel (Margaritifera margaritifera)EndangeredHaliotis DiscusEndangeredSources1.
