Periwinkles are a type of marine snail. They have a shell that is smooth and brown to brownish-gray in coloration and up to about 1 inch long. The base of the shell is white. Periwinkles may live out of the water for several days, and can survive in challenging conditions. Out of the water, they can stay moist by closing up their shell with a trap door-like structure called an operculum.Periwinkles are mollusks. Like other mollusks, they move around on their muscular foot, which is coated with mucus. These snails may leave a trail in the sand or mud as they move around
