Flat Periwinkle

Flat Periwinkle

Observation - Flat Periwinkle. Description: Annual emptying of Thanet's largest tidal pool (at low tide end would be 5m) Found in eulittoral, submerged probably some of the time here, when the sluice gates are shut. Such a flat spire thought this had to be different.
