Can periwinkles live out of water?

Can periwinkles live out of water?

All snails extract oxygen from the water using gills, so when they are out of the water their access to oxygen is greatly reduced. To manage this, the Little Blue Periwinkle can lower its body’s metabolism and in doing so, reduce its demand for oxygen. They can also store water inside their shells to help them survive.
