Authorities plan to euthanise around ninety false killer whales after a mass stranding on a remote Tasmanian beach. A total of 157 whales beached near Arthur River; many died soon  afterwards. Rescuers attempted to refloat two survivors, but rough conditions and strong currents prevented their return to the ocean. False killer whales, one of the world's largest dolphin species, have not stranded in Tasmania for over fifty years. The extremely difficult terrain and treacherous conditions made large-scale rescue efforts impossible, leading to the heartbreaking decision to euthanise the remaining survivors. Eyewitnesses described the scene as horrific, with stranded whales calling out for help. Authorities are now considering how to dispose of the carcasses, respecting the cultural heritage of the site. Experts believe that whales can become disoriented while hunting fish or following a leader into shallow waters. Over 80% of Australian whale strandings occur in Tasmania.
