The abiotic factors present in the areas where the distribution of periwinkle occurs include no water, majority rocks, and strong winds. The periwinkle is adaptable to the strong winds present in this environment because they can find shelter on rocks because they can close themselves into their shells and excrete a sticky mucous that hardens, firmly attaching it to rocks. The periwinkle can live for many days without food or water by retaining moisture in their gills which is beneficial as they live in close to the shore where the water is low.
