</p><p>The gastropods (snails &amp; slugs) are a group of molluscs that occupy marine, freshwater, and terrestrial environments.  Most gastropods have a calcareous external shell (the snails).  Some lack a shell completely, or have reduced internal shells (the slugs &amp; sea slugs &amp; pteropods).  Most members of the Gastropoda are marine.  Most marine snails are herbivores (algae grazers) or predators/carnivores.
