When I encounter these people who claim that sharks are approaching divers, the discussion ends pretty quickly. First, I tell them that I will give them $1,000 if they can get a shark to come close enough to me for a great pic without a dead or wounded fish (excluding nurse sharks, barracudas, and sand tigers in North Carolina). Second, I ask them to identify the dive site because I want to dive there to see if for myself.
They quickly stfu.
People don't understand that it is not easy getting a shark to come close even with a crate of dead, bloody fish. To this day, I have only one "acceptable" pic of a Bull Shark because I can't get them close enough to me. Great Hammers and Sandbar Sharks are very difficult to get close to; and, if one does decide to come close, it usually does one or two passes then moves on. We are having better luck feeding them while snorkeling with them; apparently, because they don't like the bubbles; but, still not easy and most are still not coming in close enough.
Most Tigers we encounter are too shy to come close enough. We see them on the perimeter, or, they give us one quick fly-by and we never see them again.
Also, the study by Neil Hammerschlag and the U of Miami demonstrated that feeding Tigers had no impact on their migration. Thus, why did the Tigers not stay at Tiger Beach where they can obtain easy food? Why are they not staying in the area with the divers that are feeding them?
Also, this past Lemon Shark migration in Palm Beach County demonstrated that we had 20 to 30 Lemon Sharks for a couple months. Then, suddenly, they all disappeared. They left us and continued on their migration. Again, why did they not stay with the divers who were feeding them?
In conclusion, you expect me to believe that these very same sharks that I cannot get close to with a crate of bloody dead fish are approaching divers who have no dead fish? Bull****! Bull****! Bull****! Again, I got a $1,000 for you if you can get one close to me without a dead fish or wounded fish.
