Manta ray night dive

The Manta ray night dive is a scuba diving excursion to view manta rays.Depending on the amount of microscopic plankton present, the number of manta rays will vary. Some days no manta rays are seen while on days with high plankton levels upwards of a dozen may be present. While diving, scuba divers shine lights up while snorkelers shine them down creating a column of light which attracts millions of minuscule plankton, which in turn attracts the manta rays.
