Buccinum undatum (common whelk) 1 (24488267430)

Açıklama:

Description: Buccinum undatum - common whelk (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 common whelk shown above is part of the Lusitanian Province: "Concentrated in the mild temperatures of the Mediterranean Sea, and extending to the warmer waters of the Canary Islands and the cooler areas of France and Great Britain, is a fairly rich fauna. These waters support dozens of unique species, such as Jacob's scallop, the oxheart cockle and the European pelican's foot."
