        The Mantas of Yap

        In this video, Jonathan travels to Yap to dive with giant Manta Rays. Manta Rays come to this area to visit a "cleaning station" where parasites are removed by cleaner fish. The tidal currents keep the Mantas from sinking to the bottom, as they have no swim bladder to control their buoyancy. The accompanying lesson plan looks at what causes ocean tides, tidal cycles, and the effects of the gravitational forces of the sun and moon on Earth.
