Pustulatirus sanguineus (Wood, 1828) - blood latirus snail from the Galapagos Islands. (apertural view) (public display, Bailey-Matthews Shell Museum, Sanibel Island, Florida, USA)

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."

Classification: Animalia, Mollusca, Gastropoda, Neogastropoda, Fasciolariidae
