According to a Google search someone at my work did after seeing that picture, there has NEVER been a shark attack in French Polynesia. Their method of feeding is to swim up thru a school of fish, collecting their food. People just aren't considered lunch, too big.
Yes, I took that during the Lagoon Discovery and Snorkel on Moorea, which had a stingray stop. I really enjoyed it. If you don't go near the drop-off, I don't think you'll even see the sharks. My husband missed them.
Carol, I'm looking forward to seeing your underwater pictures with your camera!
