Dusky Sharks Return to Hunt Seals Off Cape Cod
22 May
Summary
- Dusky sharks, once rare, are now hunting seals near Cape Cod.
- These sharks, reaching 12 feet, were previously unseen preying on seals.
- Conservation efforts have helped dusky shark and seal populations rebound.
Dusky sharks, reaching up to 12 feet in length, have been observed actively hunting seals off Nantucket and the southeastern coast of Cape Cod. This behavior, previously undocumented globally for the species, is a notable development. Researchers note that this resurgence follows a significant decline in dusky shark populations due to commercial fishing in the 20th century.
Conservation efforts, including environmental protection legislation and the Marine Mammal Protection Act, have played a crucial role in the recovery of both dusky sharks and the seal populations they now prey upon. Scientists are observing an overlap in the areas frequented by these recovering populations.
Experts caution that dusky sharks, like great white sharks, can pose a danger to humans due to their size. Beachgoers are advised to be aware of their surroundings, especially when seals or schools of fish are present, as sharks may swim close to shore in pursuit of prey.
