Thresher Sharks
Different sharks had been spotted in the waters off of the Isles of Scilly. Porbeagles and Thresher sharks were among them. While these rarely pose threats to humans, there was an account of a fisherman being decapitated by a tail swipe. This worried Gary, and he knew he would need to be careful.
He didn’t want to end up on the list of people to have gone missing in those waters. He had to make sure to pack one thing.
