What makes this whale stranding event in Tasmania unique?

This stranding is remarkable as it's the first large mass stranding of false killer whales in Tasmania in approximately 50 years. While mass stranding events in the region typically involve pilot whales, this incident uniquely features false killer whales, a little-known deep-sea species. Over 150 of these animals have beached on remote Tasmanian shores, with approximately 90 still alive during assessment. This rare occurrence has puzzled marine wildlife experts who are investigating the unusual behavior of these cetaceans, highlighting the mysterious nature of mass strandings and their significance for marine conservation efforts.
