A standing wave of sugar kelp leads in from the ocean edge across mussel-bound rocks strewn with a chain of starfish. Brown, red and green algae, lichens and barnacles, limpets, sea anemones and dog whelks array themselves in zones and cyclic progressions under the angry gaze of a red-eyed, lurid swimming crab who surveys his kingdom from a bed of pepper dulse. Vulnerable brittle stars insinuate their way towards shelter. Choughs ride the air waves.
