Amid that thrashing, panicked mess of netting and blood, officers from Fisheries and Oceans Canada had to cut four ropes. But they had to do it just right - cutting the wrong one first could have easily sent the whale into a death spiral.
"We needed to know how the gear was wrapped through the whale's mouth and around its body," Paul Cottrell, marine mammal coordinator at Fisheries and Oceans Canada, told Global News. "If we made the wrong cut, we may have freed the animal but it would still have gear on it. It was definitely a lethal situation."
After six hours, the rescue team managed to disarm this death trap - and watch the juvenile whale swim free.
And the grim of the hazards of ocean netting will remain etched into her flesh.
While this whale is expected to survive - marine experts will monitor her over the next few months - not every whale trapped in netting lives to tell the tale.
