Mass stranding leads to 80 whale deaths in NZ

A pod of 159 pilot whales have stranded themselves on the Stewart Island, 20 miles south of New Zealand's South Island, and rescuers are rushing to try and save the remaining living animals from heat, dehydration and death-by-suffication until the next tide can hopefully take them back to the sea. Currently, 20 have been refloated.
New Zealand suffers from the largest whale stranding rate in the world, and scientists are still devided on the cause of this horrible phenomenon.
