Marsh periwinkles cling to saltmarsh cordgrass at Money Point in Chesapeake, Virginia. The periwinkle is a small snail that lives in tidal marshes and wetlands near the mid- and lower Chesapeake Bay. Periwinkles rise and fall with each tide, feeding on algae growing on the blades of grass. The small snails are also known to practice “fungiculture” by chewing holes in the cordgrass and spreading waste across the cuts, allowing them to “farm” fungus.

Previously a 35-acre “dead zone,” Money Point is located along the Southern Branch of the Elizabeth River. It was once so polluted that the river bottom was nearly lifeless. Recent restoration projects led by the Elizabeth River Project and others have significantly improved the health of the waterway.
