In this April 21, 2017 photo, Renato de Negri, 15, lifts his boogie board to signal to a fellow surfer in Pacific Ocean waters that he has returned to shore, at La Pampilla beach, in Lima, Peru. Pampilla beach does not attract sharks, unlike some beaches in the United States and Australia. The greatest danger faced by night surfers is that they can crash into each other, blinded by the powerful floodlights. (Photo by Rodrigo Abd/AP Photo)
