I would definitely not be this calm if a shark was attached to my arm, I don't care how small the shark is. Videos have gone viral showing a man at a Florida beach remaining calm as rescuers tried to get a nurse shark to release it's bite on the man's bicep. Eventually rescuers were able to get it off the man's arm and back into the water. As for the guy.... he was ok and didn't receive further medical attention. So my question is, do you go back into the water after a shark uses your arm as bait? For me... .that's a BIG NO!
