Were does a flat periwinkle live?

The flat periwinkle, also known as Littorina obtusata, typically inhabits intertidal zones along rocky shorelines in coastal areas of the North Atlantic. It prefers environments such as salt marshes, tidal pools, and shores with algae and seaweed, where it can find food and shelter. These snails are often found clinging to rocks and other surfaces, where they graze on algae.
