A lemon shark wraps its jaws around a piece of bait. According to resident shark expert Andy Dehart, "Of the 450 species of sharks, only three are truly considered deadly: Great white, tiger and bull." These three species account for 50 percent of shark attacks, though Dehart says even those sharks are not all that dangerous. "Personally, I have spent more than 450 dives with tiger sharks without so much as a close call," he said. (The Discovery Channel )
