Which habitats can gastropods live in?
Gastropods are among the few animal groups that have successfully colonized all three major habitats: the ocean, fresh waters, and land.12
Marine Habitats
Marine gastropods are found in nearly all possible aquatic environments, ranging from the spring-tide line to deep-sea trenches as deep as 10,500 meters. They inhabit diverse settings, including:3
* Coastal zones: They are most abundant in and just below tidal zones, including rocky shores, sand, and mud flats.4
* Open water: Pelagic species spend their entire lives swimming in the ocean, sometimes found on the surface or among floating weeds.3
* Extreme environments: Some species have adapted to live in deep-sea hydrothermal vents or in the interstices between sand grains.3
Freshwater Habitats
Freshwater snails are widely distributed in various bodies of water, including ponds, streams, marshes, and lakes. They are also found in groundwaters and can inhabit hot springs.53
Terrestrial Habitats
Gastropods have successfully adapted to a wide range of land environments, from humid forests and mountain regions to barren deserts. They are often found in surface litter and upper soil zones, and some species can even survive above the snow line.45
