Periwinkles are widely distributed shore (littoral) snails, chiefly herbivorous, usually found on rocks, stones, or pilings between high- and low-tide marks; a few are found on mud flats, and some tropical forms are found on the prop roots or mangrove trees. Further, snails grazed S. cynosuroides more than S. alterniflora, evidenced by a greater number of radulation scars. littorea.[17]. Shell strength. Periwinkles are abundant within their range, found at depths ranging from the intertidal zone to 40 … 43°W). The herb has been used for centuries to treat a variety of ailments and was a favorite ingredient of magical charms in the Middle Ages. It is like a ribbon with rows of sharp, hooked teeth, which is used for scraping the algae off rocks. in Scotland. Phlorotannins in the brown algae Fucus vesiculosus and Ascophyllum nodosum act as chemical defenses against L. Any periwinkles left immobile at the bottom are considered dead and are discarded. L. littorea is oviparous, reproducing annually with internal fertilization of egg capsules that are then shed directly into the sea, leading to a planktotrophic larval development time of four to seven weeks. This study did not look specifically at how periwinkle density was reduced but they hypothesized that it is from a combination of processes: direct contact with the oil, exposure to toxins in the water and soil, loss of habitat… It has drastically changed the distribution and abundance of algae on rocky surfaces and altered the relationship of organisms in their habitat. The radula is used to scrape algae and detritus. A report on the state of the periwinkle industry in Ireland suggests a maximum catch size in order to preserve the population[citation needed].
