TLDR
-
Study in Marine Mammal Science identifies adult male gray seals as the culprit behind spiral wounds killing hundreds of pups on Sable Island annually.
Key Takeaways
-
765 corkscrew-wounded pup carcasses were documented on Sable Island in the 2024 breeding season alone; 359 found in a single day in 2025.
-
Wounds spiral from mouth to chest exposing bone; internal examination found large fang bite marks and claw traces consistent with gray seal anatomy.
-
All confirmed attack sightings involve adult bulls, who may target high-calorie blubber to offset fasting during breeding season.
-
Prior culprits blamed for decades – Greenland sharks, boat propellers – were ruled out; waters around Sable Island are too shallow for boats.
-
Researchers are not recommending intervention, noting uncertainty about how naturally occurring the behavior is across the population.
