Western languages generally do not distinguish between aquatic snails and terrestrial snails; in Chinese, snails refer only to terrestrial species, while the broader term snail also includes the giant shield slug. Snails are a group of animals belonging to many different families and genera. They feed on plants and lay their eggs in the soil or on trees. They are more common on tropical islands, but some survive in colder regions.
