Home›Mollusks›Conservation Status›Least ConcernBrowse ByLeast ConcernConservation 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.FactsLeast ConcernSourcesComments (0)Reader Challenges (0)FactsComparisonReproductive ModeWell-attestedOviparous (Egg-Laying) 1Least ConcernFilter Results32 entriesCommon GroupAllBivalves (Clams, Mussels, Oysters) (2)Cephalopods (Octopus, Squid, Nautilus, Cuttlefish) (17)Gastropods (Snails And Slugs) (13)Everyday GroupAllBivalves (Clams, Mussels, Oysters) (2)Cephalopods (Octopus, Squid, Nautilus, Cuttlefish) (17)Gastropods (Snails And Slugs) (13)HabitatAllAbyssal Zone (2)Coral Reef (3)Estuary (1)Freshwater (4)Grassland (4)Intertidal Zone (3)Marine (6)Neritic Zone (2)Open Ocean (5)Savanna (1)Xeric Shrubland (1)Where It LivesAllAlbania (6)Algeria (1)Andorra (6)Angola (1)Argentina (6)Australia (1)Australia (5)Austria (9)Azerbaijan (2)Belarus (2)Belgium (13)Benin (1)Bosnia and Herzegovina (4)Brazil (9)Brunei (1)Bulgaria (8)Cambodia (1)Canada (5)Chile (8)China (5)Colombia (2)Comoros (3)Croatia (7)Cyprus (2)Czechia (3)Denmark (13)Dominican Republic (1)Egypt (2)Eritrea (3)Estonia (8)Europe (1)Fiji (1)Finland (8)France (12)Gambia (1)Germany (9)Greece (5)Haiti (1)Hungary (8)Iceland (4)India (1)Indonesia (2)Ireland (9)Israel (3)Italy (9)Japan (7)Kazakhstan (1)Kenya (3)Laos (1)Latvia (6)Liechtenstein (6)Lithuania (5)Luxembourg (7)Madagascar (6)Malaysia (1)Malta (1)Mauritius (4)Mexico (7)Moldova (7)Mongolia (1)Montenegro (6)Morocco (4)Mozambique (4)Myanmar (1)Namibia (1)Netherlands (10)New Zealand (14)North America (10)North Macedonia (2)Norway (19)Pakistan (1)Papua New Guinea (2)Peru (1)Philippines (2)Poland (7)Portugal (13)Romania (7)Russia (2)Serbia (7)Seychelles (2)Singapore (1)Slovakia (5)Slovenia (7)South Africa (8)Spain (15)Sri Lanka (2)Sweden (14)Switzerland (9)Taiwan (1)Tanzania (4)Thailand (1)Tunisia (1)Turkey (3)Ukraine (8)United Kingdom (10)United States (12)Uruguay (1)Venezuela (1)Vietnam (1)Western Sahara (1)Showing the 100 most common of 105 options.DietAllCarnivore (20)Filter Feeder (2)Herbivore (3)Omnivore (5)Parasitic (1)System (Realm)AllFreshwater (4)Marine (21)Terrestrial (7)Living or ExtinctAllYes (32)ThreatsAllInvasive and Other Problematic Species, Genes and Diseases (1)Relationship to PeopleAllAgricultural or Structural Pest (3)Hunted or Fished (9)Invasive or Introduced Species (7)Kept as Pets (2)No Significant Interaction with Humans (3)Venomous or Dangerous to Humans (2)CITES AppendixAllNot Listed (32)NatureServe RankAllG5 Secure (11)GNR Unranked (4)EcosystemAllCaspian Sea (1)Coral Reef Systems (4)Deep Sea (3)Great Barrier Reef (2)Great Lakes (2)Ross Sea (1)TaxonomyAllBivalvia (2)Cephalopoda (4)Gastropoda (10)Haliotis (1)Helicidae (2)Octopoda (10)Sepiida (2)Spirulida (1)Show ResultsBrowseCompareSelect all 32Arion aterLeast ConcernBlue-ringed OctopusLeast ConcernCalifornia Two-spot OctopusLeast ConcernCoconut OctopusLeast ConcernColossal SquidLeast ConcernCommon CuttlefishLeast ConcernCommon OctopusLeast ConcernConus magusLeast ConcernCuttlefishLeast ConcernDumbo OctopusLeast ConcernFirefly Squid (Watasenia scintillans)Least ConcernGarden SnailLeast ConcernGeography ConeLeast ConcernGiant Pacific OctopusLeast ConcernGiant SquidLeast ConcernGlass OctopusLeast ConcernGolden Apple SnailLeast ConcernGreat Grey SlugLeast ConcernGreat Pond SnailLeast ConcernGrey Field SlugLeast ConcernGrove Snail (Cepaea nemoralis)Least ConcernHaliotis irisLeast ConcernJapanese Flying SquidLeast ConcernLeopard SlugLeast ConcernMimic Octopus (Thaumoctopus mimicus)Least ConcernOctopus cyaneaLeast ConcernPaper NautilusLeast ConcernQuagga MusselLeast ConcernRam's Horn SquidLeast ConcernRoman SnailLeast ConcernTextile ConeLeast ConcernZebra MusselLeast ConcernSources1.
