![]() This is known as the “fish trap effect” and it may have been what happened to one unfortunate juvenile male that washed up on Cape Cod in February 2022. This can happen during the winter months when they get trapped in shallow areas as the tide rolls out and temperatures drop. Thresher sharks can tolerate cold temperatures, but they’re not immune to cold shock. The farthest tagged common thresher shark during that time was a female caught within the English Channel off the Isle of Wight, England, in July 2020.Īnother opportunity to collect shark data is when they wash ashore. She was caught off Montauk, New York, in September 2019. The largest common thresher shark tagged during that time was a female measuring about 14 feet long. ![]() In more recent years, between 20, 31 common thresher sharks were tagged through our program. It is a collaborative citizen science effort that engages thousands of recreational and commercial fishers. It’s the longest continuous shark tagging program in the world, started in 1962. ![]() One of the ways we learn about the life history of common thresher sharks is through our Cooperative Shark Tagging Program. Our Apex Predators Program conducts life history research and long-term monitoring activities essential for the assessment and management of this species. What’s really fascinating is how they use their long caudal fin like a whip to stun fish while hunting for food. Their long sickle-shaped caudal fin is one of the most distinguishing characteristics of thresher sharks. While they can grow to about 18 feet long, about half of their total length is all fin. In the northwest Atlantic Ocean, they range from Newfoundland to Cuba. Common thresher sharks are found in temperate waters around the world. ![]()
