JoJo has been hit by a boat propellor

Hi All, JoJo has been injured by a boat propellor. He has a large gash on his head. Mark the island vet has seen pictures. He feels it will mend as have many of the other gashes he has sustained. The worry is that he can eat and that sharks aren't attracted to and seepage coming from the wound. He also feels it's important that he's felt alone to heal and people aren't taking advantage of his injury to be close to him. I have witnessed this before but I was there to ask people to give him his space. Please implore anyone with a boat to be careful of JoJo, he's an older dolphin who loves to hang with boats but he doesn't move as quickly as he used to. Many boat captains go way too close obviously this one did. A very concerned Jay
