Story: Coastal shoreline

Common sea snails (1st of 3)

Common sea snails

A large cat’s eye snail, surrounded by tiny periwinkles, rests upside down on coastal rocks. The snail has retreated into its shell, closing its blue-green ‘trapdoor’. This protects it from predators, and from drying out. The periwinkles seal their openings with mucus and may seek shelter in crevices when the tide is out.
