Diver saves Whale shark

A dive team stumbles across a whale shark trapped in a commercial fishing line. Sensing the diver is there to help, the goliath lies still while the rope is cut. The rope had cut deeply into the shark's body . It must have been there for years because it was covered in barnacles.  Imagine the relief to feel the painful constriction cut away. The giant slowly glided away .  Just to have been instrumental in saving him from his torturous bonds was all the thanks the diver needed.
