This is quite a moving story of when a dolphin, entangled in fishing line with a hook was lodged in its pectoral fin, circled a group of divers before, quite literally, pleading for help by pushing her injured fin against one diver who, shakily, took out his knife and began attempting to untangle her.
At one point, the dolphin swims up to the surface to breathe, but comes right back to the diver for the next round of untangling.

And whilst were on the subject of marine mammals, I urge you to check out Blackfish, the documentary showing real footage of the brutal history of how Orcas came to be in sea entertainment parks around the world and the devastating effects this has had on their well-being and thus, their trainers.
