Canadian researcher Zoe Lucas who works on Sable Island has conducted an eight-year study of "corkscrew" seal injuries.
She maintains Greenland Sharks are capable of inflicting such wounds.
However, scientists at the Sea Mammal Research Unit (SMRU) at the University of St Andrews, U.K have ruled out the possibility of the deaths being caused by sharks. They claim mechanical ducts are causing these wounds.
Having a shark blog that goes back over three years allows us to cover the stranger side of sharks and this enduring predatory mystery.

Underwater Thrills is officially offering a fine bottle (signed) of 2005 Floodplain Proprietor Red from Napa Valley, California to any U.K researcher who can prove without a doubt that the Corkscrew Killer is in fact a man made object or machine.
