About gilled snails:
Snails are defined as either gilled or pulmonate. Pulmonate snails have lungs, can breathe air, and are generally hermaphroditic. The shells are "left-handed". Gilled snails have gills, have separate sexes, and their shells are "right-handed". Gilled snails eat decaying plants and algae. They can close the opening of their shell with a plate called an operculum. Eggs are laid in the spring. They live two to five years.Taxonomy:
