Mysterious Deaths of Endangered Sawfish Puzzle Experts in Florida

Dozens of endangered smalltooth sawfish have been found dead in the Lower Florida Keys, exhibiting bizarre behavior of "whirling and spinning" onto beaches, leaving experts puzzled. The National Oceanic and Atmospheric Administration has launched an unprecedented "emergency response" to investigate the cause, with at least 109 sawfish affected and 28 killed. Despite necropsies showing no signs of infection or contamination, the cause of this erratic behavior remains a mystery. Efforts are underway to rescue and rehabilitate affected sawfish, while officials urge the public to report any similar behavior.
