I'm not that tastey and I smell bad.
At the Blue hole dive site the sharks are used to divers and in general sharks, though curious won't bother you if you don't bother them. That said it is a bit of a rush when they swim up beside you and they are pretty much all you see at 135 feet at that dive site. It get's a little dark and eery but very cool. Unfortunately at that depth my camera was much slower than the sharks so I never got any good quality pics.
