The gastropods (snails & 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 & sea slugs & pteropods). Most members of the Gastropoda are marine. Most marine snails are herbivores (algae grazers) or predators/carnivores.
From museum signage:
"This world-record shell, a member of the Family Fasciolariidae, was collected at Punta Cormorant, Floreana Island, one of the Galapagos Islands. The coarse-looking shell measures 75.1 mm."
