Thresher Shark Dies After Stranding in Massachusetts
4 Dec
Summary
- A 14-foot thresher shark died after becoming stranded on Mayo Beach.
- The shark was found in poor condition with visible injuries.
- Thresher shark strandings are common in New England during colder months.

A 14-foot thresher shark was found stranded on Mayo Beach in Wellfleet, Massachusetts, succumbing to its condition shortly before rescuers could intervene. The New England Coastal Wildlife Alliance (NECWA) responded to the scene, noting the shark appeared injured and was in poor health.
The large-eyed, slender shark displayed its characteristic whip-like tail, but unfortunately, its struggles ended on the shore. NECWA's Marine Biologist, Krill Carson, stated that the shark was alive when first sighted but in a significantly weakened state, prompting a necropsy to determine the cause of death.
NECWA explained that such strandings are not uncommon during the fall migration of thresher sharks in New England, particularly along Cape Cod. These animals can become disoriented, taking wrong turns into shallow waters. Prolonged exposure to cold temperatures, below 50 degrees Fahrenheit, can lead to cold-shock, ultimately proving fatal for the sharks.
