When the two divers discovered the manta was slow to move because it was stuck in fishing line, a third diver, Brian Thompson of Canada, came to its aid.

Thompson cut the fishing line from the manta, which can have a wing span of up to 18 feet. At the first sign of freedom, the manta appeared to celebrate by doing a partial backflip.

Thompson took the fishing line out of the water and cut it up so that each diver could take home a piece, Monteiro and Passaglia noted.

“It’s our trophy now,” they wrote.

The YouTube video of the rescue, which was posted Thursday, has nearly 800,000 views as of today.
