How stealth is this shark as it comes across the reef towards me? Check out how well this black tip reef shark blends into its environment as it approaches. Very stealth like. We had some great shark encounters on this trip on Australia's Great Barrier Reef, from memory we swam with 8 different species of sharks...would have been 9 but we weren't fortunate enough to see the hammerhead that was hanging around for a few days. When it comes to experiencing underwater life on the reef. I'll say it again and again, this place is pretty hard to beat.
