In Kanagawa, Japan, a giant ray smiles brightly when fed. Divers enter the aquarium to see if there are any dead fish, but are seen by rays as a good time to forage. When the diver has fed all the food, the rays are still reluctant to let the diver go. The photos were taken by British professional photographer David Williams at the Niigata Aquarium, who said: "I originally wanted to take pictures of jellyfish, but I was attracted by the rays behind the giant glass and thought it was particularly interesting, so I recorded it. ”
