Amazing mass migration of Golden Rays

Sandra Critelli, an amateur photographer, stumbled across the biannual mass migration of thousands of Golden Rays gathering off the coast of Mexico while looking for whale sharks.


She said: "It was an unreal image, very difficult to describe. The surface of the water was covered by warm and different shades of gold and looked like a bed of autumn leaves gently moved by the wind."
