This handout from the New Zealand Department of Conservation taken and released on February 10, 2017 shows pilot whales, which beached themselves overnight, at Farewell Spit in the Golden Bay region at the northern tip of New Zealand's South Island. More than 400 whales were stranded on a New Zealand beach Friday, with hundreds already dead as volunteers raced to refloat the survivors, the Department of Conservation said. / AFP PHOTO / New Zealand Department of Conservation / STR / RESTRICTED TO EDITORIAL USE - MANDATORY CREDIT "AFP PHOTO / NEW ZEALAND DEPARTMENT OF CONSERVATION" - NO MARKETING NO ADVERTISING CAMPAIGNS - DISTRIBUTED AS A SERVICE TO CLIENTSSTR/AFP/Getty Images
