(Large Periwinkle, Littorina keenae or L. planaxis and Black Periwinkle, Littorina scutulata or L. plena) Range & Habitat: Common periwinkles are mainly found on rocky coasts or sandy or muddy habitats on the shores of the Atlantic Ocean. For example, where did plants and animals find refuge during the last ice age? The reason why this happens only to mature snails is not yet known, but one hypothesis is that a mature snail will excrete a signal substance which attracts the P. ciliata larvae. They live near the shore on various ocean bed materials, usually rock, and less often, on sand or mud. They support high levels of biodiversity. 1.
