When Michael Fishbach set out for his day of boating around the beautiful waters of the Sea of Cortez, he probably didn't think that it would be the day he and his friends would become wildlife heroes. As luck would have it, that's exactly what happened.

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?

Fishbach has co-founded The Great Whale Conservancy to help protect whales. This week, the Associated Press reported that the International Whaling Commission held their annual talks to discuss the large dispute between anti-whaling nations and the handful of countries who hunt whales, despite a 1986 moratorium.

This isn't the first time that a whale has put on a show in front of humans. Just last month, a group of whale watchers got an unexpected treat when they witnessed a twirling finback whale. Take a break from work and enjoy this hearty slice of human kindness (or jump to 6:40 if you're short on time).
