Periwinkles typically grow along rocky shorelines, tide pools, and in salt marshes. They are commonly found in temperate regions around the world. Periwinkles thrive in intertidal zones where they can feed on algae and other plant material.
Common periwinkles and flat periwinkles compete primarily for similar resources, such as food and habitat space. Both species feed on algae and detritus found on rocky shorelines, leading to direct competition for these limited resources. Additionally, their overlapping habitats can result in territorial disputes, further intensifying the competition for survival in their shared environment.

Periwinkles are small marine snails that primarily feed on algae, diatoms, and other plant material. They use their radula, a specialized feeding organ, to scrape algae from surfaces and consume it as their main source of food.
