(abapertural view) (~1.85 centimeters across at its widest)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.Classification: Animalia, Mollusca, Gastropoda, Euomphalina, PlatyceratidaeStratigraphy: Onondaga Limestone, Middle DevonianLocality: unrecorded/undisclosed site at or near Port Colbourne, Welland County, Ontario, Canada |
