Cerithium muscarum Say, 1832 - fly-specked cerith snail shell from the Bahamas (modern; apertural view; 1.5 centimeters tall)
The gastropods (snails and 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 (slugs, sea slugs, pteropods). Most members of the Gastropoda are marine. Most marine snails are herbivores (algae grazers) or predators/carnivores.
Cerithium muscarum is a member of Family Cerithiidae, a group of algae-grazing and deposit feeding snails that occupy seagrass beds and sandy seafloors.
Locality: shoreline of San Salvador Island, eastern Bahamas
