I had a chance to visit Kohama Island in Okinawa this March, where a beautiful coral reef expanded continuously near the sea shore. It is well known that coral is composed of inorganic calcium carbonate (Aragonite). We can find red and blue coral in addition to a popular white coral. I don't know how they are colored. We admire the . surprising colorful nature. Shells are also composed with calcium carbonate and keep a number of shapes and colors as well.
