epa05593700 A handout picture provided by Wildlife Photographer of the Year. Snapper party, Tony Wu, US Winner, underwater category For several days each month, thousands of two spot red snappers gather to spawn around Palau in the western Pacific Ocean. The action is intense as the fish fill the water with sperm and eggs, and predators arrive to take advantage of the bounty. Noticing that the spawning ran ‘like a chain reaction up and down the mass of fish’, Wu positioned himself so that the action came to him. On this occasion, with perfect anticipation, he managed to capture a dynamic arc of spawning fish amid clouds of eggs in the oblique morning light.
