Often confused with seeds or even oak apple galls, Leca®, or Lightweight expanded clay aggregate, is commonly found on the strandline on both the north and south coast of Cornwall and elsewhere. The product is commonly used horticulturally so may enter the sea via river systems and water courses from gardens and the horticultural industry.
The Leca® here was collected and photographed within Carnsew Pool, Hayle, Cornwall. 17.03.16.
