Scaphella junonia (Lamarck, 1804) - Juno's volute snail (abapertural view) from Florida, USA. (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. Info. from Witherington & Witherington (2007): "Junonias (Scaphella junonia) have unmistakably flamboyant shells with squared, chestnut spots on a background of pinkish ivory. They have a wide aperture and rounded whorls that spin into a distinct spire with a rounded apex. Junonias live on offshore reefs. Junonia shells are a rare find but they inspire a common quest. Because Florida is the hotspot for this rare and spectacular shell, junonias receive much attention, especially from visitors to Sanibel where, island-wide, roughly one junonia per day is found. Like their shell, the soft parts of the living junonia are covered with spots. Junonias are predators of bivalves." Museum-provided info.: "The treasured junonia, rarely cast ashore on Sanibel beaches, lives far offshore in great numbers. A member of the volute family, Scaphella junonia (Lamarck) takes about 5 years to reach adult size. It ranges from off North Carolina to the Gulf of Mexico." The shell shown above is the largest Scaphella junonia shell from the Sanibel Island area that is known to the museum. Classification: Animalia, Mollusca, Gastropoda, Neogastropoda, Volutidae Locality: Sanibel Island, southwestern Florida, USA More info. at: <a href="https://en.wikipedia.org/wiki/Scaphella_junonia" rel="nofollow">en.wikipedia.org/wiki/Scaphella_junonia</a> |
