Found a couple these wee beasties, so a jar of sea water was procured and they'll go back to a rock pool shortly. The common periwinkle or winkle (Littorina littorea) is a species of small sea snail, a marine gastropod mollusc, mainly lives on rocky shores and sometimes found in small tidal pools, in the higher & middle intertidal zone. It may also be found in muddy habitats such as estuaries. L. littorea is an omnivorous, grazing intertidal gastropod, primarily on algae, but it will feed on small invertebrates such as barnacle larvae. They use their radulae to scrape algae from rocks, (in the salt marshes, graze algae from the cord grass, or from the biofilm that covers the surface of mud in estuaries).
