Blue Periwinkles are very small blue- grey shells that feed on microscopic algae invisible to the naked eye. They live at the upper drier levels of the platform and are able to survive a long time out of water. At low tide they are often found huddled together in cracks and crevices. They follow each other and recognise and respond to familiar surroundings.
