A team of researchers managed to capture on video one of the most heartwarming footage ever. The video already went viral and shocked everyone. While swimming near a humpback whale in the South Pacific, Nan Hauser found herself in the situation of swimming away from a shark that already caught her smell.
But the shark was also detected by the whale. The footage captured the moment when the whale lifted its fin and covered the biologist in order to protect her. You can clearly see that it even touches the diver with its head, pushing her away from the shark.
At one point the giant whale pushes the diver to the surface. See it for yourself in the following video.
