Fissurella barbadensis (Barbados keyhole limpet shells) (St. Thomas, Virgin Islands) 1
Description:
Description: English: Fissurella barbadensis (Gmelin, 1791) - Barbados keyhole limpet shells from the Virgin Islands. (exterior view) 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. Seen here are three beachworn keyhole limpet shells, Fissurella barbadensis. Unlike "normal" snails, limpets lack a conispirally-coiled shell and instead have a cap-shaped shell. They typically occupy intertidal zone hard substrates and use a radula to scrape algae from rock surfaces.
