More than 100 pilot whales died after being found stranded on a remote beach in New Zealand, conservation officials said Monday, November 26. The whales were discovered just over a mile apart on Mason Bay, Stewart Island, a sparsely populated island in the country's south. Those that weren't dead at the time were later euthanized. Ren Leppens, a Stewart Island operations manager for the country's Department of Conservation, said the remote location and the condition of the surviving whales made it impossible to save them.
