Amazing! Swimming with sharks at heaven on earth

Scuba divers watch as a four meter giant manta ray visits a cleaning station just outside Hanifaru Bay of Maldives' remote Baa Atoll, August 11, 2011. Every year, hundreds of whale sharks and giant manta rays gather for their annual feeding frenzy of plankton in July and August, in the geologically unique Hanifaru Bay. For reasons of conservation, Maldives is likely to shut down Hanifaru Bay to divers, making this the last season divers can see this one-of-a-kind phenomenon. [Photo/Xinhua/Agencies]
