What are the challenges and investigations surrounding the false killer whale stranding in Tasmania?

Wildlife officials are facing significant challenges in refloating the stranded false killer whales due to their considerable weight. According to State Wildlife Officer Brendan Clark, these migratory animals roam open waters globally, making their rescue particularly difficult. To understand this rare event—the first such stranding in 50 years—experts are conducting post-mortem investigations and sampling deceased dolphins. Despite these efforts, the reasoning behind why approximately 150 false killer whales became stranded remains unclear, with officials confirming there is currently no intel on the cause of this unusual mass stranding.
