Cerithidea pliculosa

Horn shells live on the mud at the base of cordgrass stalks. They can survive being covered by the tides that wash the salt marsh every day.

These small snails graze on algae that grow on the mud in the salt marsh. In turn, horn shells provide food for water birds which filter them from the mud.
