Coffee Bean Trivia

Description: Niveria pediculus (Linnaeus, 1758) - umbilical view of a coffee-bean trivia snail shell, 1.35 cm tall. Family Triviidae - trivias generally have a cowry-like shell shape, with the shell’s spire covered as a result of sub-planispiral coiling. Unlike cowries, which have a smooth glossy adapertural shell surface, trivias have prominently ridged and grooved shell surfaces. Trivias prey on tunicates and some octocorals.

Description: English: Niveria pediculus (Linnaeus, 1758) - coffee-bean trivia snail shell (modern) (abapertural 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. This is a beachworn coffee-bean trivia snail shell, Niveria pediculus, which is a member of Family Triviidae. Trivias generally have a cowry-like shell shape, with the shell’s spire covered as a result of sub-planispiral coiling. Unlike cowries, which have a smooth and glossy abapertural shell surface, trivias have prominently ridged and grooved shell surfaces. Trivias prey on tunicates and some octocorals. Classification: Animalia, Mollusca, Gastropoda, Triviidae Locality: Brewers Bay, St. Thomas, western Virgin Islands. Date: 29 September 2020, 17:18:17.
