Divers swim beside millions of silverside fish at Devil's Grotto, Cayman Islands. Swimming in unison, millions of silverside fish dwarf the divers. The fish create waves of silver light as they move around the grottos that lie beneath the surface of the Caribbean Sea. These amazing photographs were captured by Belgian photographer Ellen Cuylaerts, 44, on a diving trip to the Devil's Grotto, Cayman Islands. “Every year predators and divers await the arrival of the silversides”, says Ellen, now of Grand Cayman, Cayman Islands. “It's a beautiful spectacle that I'm able to witness close to home. My love for summers in the Cayman Islands has everything to do with the arrival of the silver magic. Tarpons and other predators hunt the silversides, but by swimming in unison they can escape and continue to grow bigger”. Each year millions of these silvery fish arrive in coastal waters between June and August. (Photo by Ellen Cuylaerts/This is Guavo Media)
