The guests were very courteous giving up there time in the water with 5 Oceanics and the dusky, so that we could attempt the rescue as safely as possible. Vincent and Debra Canabal, owners of Epic Diving, along with Amanda Cotton, the expedition leader, slipped back into the water with a few tools, and cameras. We used some more bait to lure the shark closer to us, as well as to distract him from our mission. We were all fearful that we'd only get one attempt at the rescue. If the shark felt pain or threat, he'd likely take off and we'd never seem him again.
As the shark came in, we managed to get right behind his head (and mouth) as he approached to bait. As gentle as possible, the rope was lifted from his flesh and a pair of Tripura shears made quick work to cut it off. While doing this, the shark rolled over completely epithelial a bit if thrashing, and spun right out if the rope.
At that same moment, all 5 oceanic whitetip sharks changed their behavior immediately. They simultaneously charged at the divers and dusky shark in a rather agitated way. Fortunately, the crew was able to keep the oceanics at bay and they won pent back to their normal, calm behavior just as quickly as they changed.
