Low tide and the sand stretches out in front of me, rippling out to the sea. The water in the rock pools has been warmed by the sun all afternoon. I take off my shoes and paddle in, gasping slightly at the cold. Not as warm as it appears! In the depths, the sea lettuce waves gently in the current. Gentle steps I take, staring into the water. Puffs of sand rise up as the tiny flatfish and blennies swim rapidly away. A young plaice – no bigger than my thumb nail – lies camouflaged on the bottom. Sensing my approaching toes it flees rapidly away. A crab stares at me from behind a curtain of seaweed, before burying himself in the sandy floor. Slowly I wade my way up to the head of the bay, stopping to stare now and then.
