caption: The image shows a close up of an edible cockle, a small shell, on the beach surrounded by seaweed. The cockle is a light brown color with a white underside and a pinkish-red center, and its shell is covered in a pattern of small bumps and ridges. The seaweed is a vibrant green color and is scattered around the shell, adding a splash of color to the otherwise muted tones of the beach.
