Swimming with the Dolphins

I can't take any credit for this video, but when I found it on YouTube, I just had to share it.  

Just to set up the action, a group of divers and snorkelers are doing a nighttime "Manta Ray Feeding Dive" (which sounds pretty cool by itself) in Hawaii.  A dolphin shows up and begins to "hang around" the divers. One diver notices the dolphin appears to be moving irregularly, and finds fishing line tangled around a fin.

The video shows the interaction between the divers and the dolphin.  It's one of those videos I reserve the word "amazing" for.   The dolphin - diver interaction begins around 4:00 into the video, but the footage of the manta rays at the beginning is pretty spectacular on its own.

Notice that when the diver tries to cut the dolphin loose, he uses a pair of underwater shears.  I always carry a pair of EMT shears for cutting fishing line that I get tangled in; I never imagined something like what this video shows could happen.
