Soil is a major part of a snail's habitat. In Europe, predators such as thrushes and blackbirds keep Helix populations in check and cold winters limit their breeding to warmer months of the year. In 2012, Shinichiro Wada reported that the land snail Tornatellides boeningi, found in the Hahajima Island in the western Pacific, could survive being swallowed by the Japanese white-eye bulbul and the brown-eared bulbul.Both predators were fed adult snails approximately 2.5mm in shell height.

Of particular interest from the fisheries management point of view is how the invasive New Zealand mud snail, Potamopyrgus antipodarum, can alter the diet of fish and crayfish. Shell-crushing predators include some bigger species like pumpkinseed sunfish and mud minnows. Hydrobiologia 775, 213–230. Introduced species interact both directly and indirectly with native species. energy flow) of the native food web is disrupted.
