In October of 2008 while leading a WWF Micronesia tour a group of snorkelers were drifting along a current swept channel on the remote island of Pohnpei. A high concentration of plankton had attracted hordes of small fishes, which in tern had caught the attention of giant Manta Rays. The 12 wide filter feeding Rays began barrel rolling through the dense concentrations of plankton. The snorkelers were treated to close up looks at the majestic rays as they rolled and swept just below the surface.
