It matters little to the overall shape of things in the world that I know barnacles stand on their heads and eat with their feet. But I can tell you that it makes a great difference to me when I stoop at ocean’s edge and see them feed. What a delightful moment. Pleasure is immediate when I watch their fern-like feet search the shallow water for food. I feel like God has let me in on a private joke. I am glad I learned about barnacles.
