The Harbour Island of Bahamas is a coral island, but the beach is pink, so its called “ heavenly creatures”. There is a kind of monad called “foraminifer” attached to the rocks on the beach. They are tiny in size, able to secrete pink calcium or siliceous and form the pink shells. Their remains become pink “grain of sand” under the action of the waves after death. After mixing with white sand beach, the pink beach appears. To protect this pink beach, people should protect the living environment of the foraminifers well.
