Each year lunar tides and Indian Ocean monsoon currents combine to drive plankton and tropical krill into confined bays around the islands of the Maldives. These protein-packed waters invite large concentrations of manta rays to an all-you-can-eat buffet. Despite their large size, with wingspans stretching up to 12 feet (3.6 meters), as many as 200 mantas may pack a football field-sized bay during these feeding frenzies.
