Cerithium caeruleum Sowerby, 1855 - cerith snail shell from Kenya (modern; apertural view)
The gastropods (snails and 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 (slugs, sea slugs, pteropods). Most members of the Gastropoda are marine. Most marine snails are herbivores (algae grazers) or predators/carnivores.
