Idyllic beaches and coral reefs in the Indian Ocean: The Maldives are a miracle of nature. Cleaner fish operate something akin to a wellness parlour, bizarre sand eels live in tubes which serve as a retreat in case of danger, small gobies live in a flat share together with blind crabs and at night, nurse sharks literally suck their prey out of the reef. Should a mass of plankton occur, manta rays simply glide through the depths with their mouths wide in order to still their hunger.
