no, they aren't de-barbed - its very cruel. Stingrays will only attack if they're threatened. To date only 3 people have been killed by a stingray attack. The stingrays in shark reef are fairly small. If this is a Steve Irwin-related phobia do not worry, he was off shore, in the wild with huge rays they aren't the kind that are at shark reef, in fact shark reef is a lot deeper than it looks they won't come too close to you.
