Dozens of dolphins died on the shores of New Zealand, despite the efforts of rescuers, about 50 pilot whales washed up on a rocky beach near Cape Placer. Local residents, environmental department workers and volunteers came to help. They soaked the animals in the water and tried to return them to the ocean at high tide, but were unable to save the last four survivors. Scientists have not yet determined the cause of the incident. One version is related to the behavior of pilot whales: these animals are so attached to their group that they can follow each other even into dangerous shallow water. Such mass cases have not been recorded in this region since the 1990s.
