Seven years ago we found these little shapes in the sand on Agri Irini beach. They intrigued our curiosity--were they man-made, or part of an animal or plant? For the first year or two we found them no place else, but since then we have on one or two other beaches.
We even asked a local taverna owner who grew up on Agri Irini. He claimed to not know what they were. They are many colors and shapes of a resin-like texture.
What else can I say? The white scale is inches; the yellow is centimeters.
