Mass Migration of Stingrays

Looking like giant leaves floating in the sea, thousands of Golden Rays are seen here gathering off the coast of Mexico . The spectacular scene was captured as the magnificent creatures made one of their biannual mass migrations to more agreeable waters. Gliding silently beneath the waves, they turned vast areas of blue water to gold off the northern tip of the Yucatan Peninsula . Sandra Critelli, an amateur photographer, stumbled across the phenomenon while looking for whale sharks.
