This video says about itself:
Occurred on February 9th, 2017 / Jensen Beach, Florida, USA
“Myself and two of my buddies were at the beach fishing for jacks and bluefish while we saw a shark struggling in the surf. We realized it was wrapped around something and ran to see if we could help. At this point my buddy Adam jumped into the surf to rescue the blacktip shark. We then got the fishing line unwrapped from around the body and took the hook out of its jaw. Adam then released the shark and it swam off to live another day.
