Joby Rohrer and his family were enjoying a day of diving off the coast of Lanai, Hawaii, when they spotted something that made them change their plans.
There, in the water not far from them, was a massive whale shark. Wrapped around her was a large rope, strangling her body.
What Rohrer didn't know at the time was that, a few weeks earlier, this same animal had been spotted. Wildlife officials were urging the public to alert them if she was sighted again.
