Flat Periwinkle are the cutests of all rockyshore snails – thats a fact. Called flat periminkles because they dont really have the pointy bit of the shell and are much more spherical. These can be found living among seaweeds, particuarily types of Fucus. They can be black, brown, white, yellow, orange! They really range in colour, and once you have a quick nose through the seaweeds are relativlty easy to spot.
