Blue oceans hide from us their treasures under the layers of crystal water that glitters in the rays of the declining sun. They are so deep that you will never reach to the bottom, where there are reef castles and beautiful water flowers that blossom in faerie colors. Here and there the delicate shine is pouring from the mistyrose and opalescent pearls in the escallop-shells. In this kingdom of the ocean live mermaids, fascinating creatures with fish tails, wreath of flowers on their pretty heads and the eyes that are shining like precious aquamarine. Sometimes they rise to the surface of the ocean and sing their songs while sitting on the cliffs in the moonlight. Their magnetic voices are beckoning, but they bring death to everybody who hears this melody. These divine female creatures are dangerous, but so luring. They are eternal mistresses of the oceans and deep waters. Let’s enjoy the splendid tone of this underwater mystery.
