Oliva incrassata (angled olive snail) 1 (24762873760)

Description:

Description: Oliva incrassata (Lightfoot in Solander, 1786) - angled olive snail (abapertural 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. The angled olive snail shown above is part of the Panamic Province: "Much richer in species than its Caribbean counterpart, the tropical-water Panamic area extends from the Gulf of California, along the Pacific coast of Central America to Ecuador. Known for its wide tidal ranges, its sandy-mud shores and offshore waters abound in colorful murexes, cones, olives and cowries. Over 2,500 species are known from here, including the endemic tent olive."
