Whale stranding incident kills 477 marine mammals on New Zealand beaches

Some 477 pilot whales have died after stranding themselves on two remote New Zealand beaches over recent days, officials say. None of the stranded whales could be refloated and all either died naturally or were euthanised in a “heartbreaking” loss, said Daren Grover, the general manager of Project Jonah, a nonprofit group which helps rescue whales.
