The group came upon a stranded humpback whale who was so tangled in a mesh of nylon netting that she was beginning to drown, and as Fishbach noted in this video, was possibly an hour from death. The crew worked tirelessly for more than an hour to free the stranded whale and, to their elation, eventually succeeded. Then, magic happened.
For miles on their ride home, the whale put on a beautiful show — perhaps to say “thank you” to her rescuers? The magic starts at 6:20.
