        "transcript": "<p class=\"MsoNormal\">There are only three sharks that regularly attack humans: the massive great white, the swift, sleek tiger and the often-ignored but dangerous bull shark.</p><p class=\"MsoNormal\">Mike Heithaus from Florida International University studies the bull.</p><p class=\"MsoNormal\">Mike Heithaus: \u201cProbably get the name bull shark because they\u2019re so big and stocky.  I kind of think of them more as the pit bull of the seas.\u201d</p><p class=\"MsoNormal\">It\u2019s a fitting description;</p><p class=\"MsoNormal\">Bull sharks can be tenacious and aggressive.</p><p class=\"MsoNormal\">They\u2019re not as large as the great white, but female bulls can grow to over 11 feet and weigh up to 500 pounds.</p><p class=\"MsoNormal\">They also have one very special characteristic:</p><p class=\"MsoNormal\">Mike Heithaus:  \u201cOne of the most amazing things about these bull sharks is that they go from marine to freshwater with no problems.\u201d</p><p class=\"MsoNormal\">Bulls have been found thousands of miles upstream in both the Mississippi and Amazon rivers.</p><p class=\"MsoNormal\">They also are believed to hunt in the same shallow coastal waters where unsuspecting beachgoers frolic in the summer.</p><p class=\"MsoNormal\">They are also opportunistic hunters\u2026 they\u2019ll eat just about anything.</p><p class=\"MsoNormal\">Mike wants to know more about bull sharks and their feeding habits so he\u2019s attached Crittercams to the sharks \u2013 underwater cameras equipped with satellite tags.</p><p class=\"MsoNormal\">The Crittercam reveals at least one other bull in the region, which raises the intriguing possibility that these sharks may be interacting.</p><p class=\"MsoNormal\">It also suggests the bull shark may be a keystone species, which means they may be a critical influence on the structure of the ecosystem.</p><p class=\"MsoNormal\">Satellite data also confirmed that the bulls stay put, never venturing far from where the team caught them\u2026</p><p class=\"MsoNormal\">That\u2019s more proof that these animals may be an important part of the coastal environment.</p><p class=\"MsoNormal\">But in regards to sharks and us, it showed that bulls do like to hunt and hang out in the same shallow waters we flock to every summer.</p><p class=\"MsoNormal\">Ultimately though, it does us all good to remember that you are more likely to get struck by lightning, than bit by a shark.</p>",
