A humpback whale has been rescued off of the western coast of Canada following a four-day struggle captured on video.
A team from the Fisheries and Oceans Canada Marine Mammal Rescue was able to free the whale from being entangled in over 50 ropes, fishing gear and floats.
“I’ve never seen anything like it,” Paul Cottrell, marine mammal coordinator for Fisheries and Oceans Canada, told CBC radio. “The animal couldn’t open its mouth and then the body wraps.”
The effort took place between Sept. 2 and 6 as Cottrell was conducting a necropsy on a deceased fin whale in Prince Rupert, British Columbia.
“Our team was all there, all our equipment … so we actually went out with the satellite tag with the team and we were able to locate the whale,” Cottrell recounted to the radio station.
The department credited the successful release of the whale to the rescue team and provincial fishery officers in a statement to USA TODAY Monday.
