Nature Trail on the Seashore At this season of the spring tides, the shore is particularly interesting to naturalists. JOHN BARRETT takes us on a Radio Nature Trail on the coast of Pembrokeshire to see some of the worms, sponges, sea anemones, crabs, fish and shells which are rarely uncovered by the tide.
