Distribution Found on rocky shores all around our coasts. Proteins from this periwinkle may inhibit the growth of bacteria (Lopez-Abarrategui et al., 2012). Rocky intertidal habitat supports a diverse and conspicuous assemblage of invertebrates and luxuriant macroalgal growth that produce more organic material than almost any other intertidal habitat (Lees et al. Given how abundant this snail is in its native and invasive habitats, the rarity of fossils and subfossils in North America offers little support for the existence of a native population in North America.
