Pollution indicator, predatory responsibilities, and prey roles are the functions of garden snails. The terrestrial pulmonate gastropod mollusks in question (Cornu aspersum) inform the gardener of environmental pollution by their ability to sequester heavy metals in their shells. They also serve as popular predators of crushed animal matter and rotting plant materials, unpopular predators of edible and ornamental plants, and welcome prey for garden birds, frogs, and lizards.
