    "transcript":"\u003Cp class\u003D\u0022MsoNormal\u0022\u003EThere are only three sharks that regularly attack humans: the massive great white, the swift, sleek tiger and the often\u002Dignored but dangerous bull shark.\u003C/p\u003E\u003Cp class\u003D\u0022MsoNormal\u0022\u003EMike Heithaus from Florida International University studies the bull.\u003C/p\u003E\u003Cp class\u003D\u0022MsoNormal\u0022\u003EMike Heithaus: “Probably get the name bull shark because they’re so big and stocky.  I kind of think of them more as the pit bull of the seas.”\u003C/p\u003E\u003Cp class\u003D\u0022MsoNormal\u0022\u003EIt’s a fitting description\u003B\u003C/p\u003E\u003Cp class\u003D\u0022MsoNormal\u0022\u003EBull sharks can be tenacious and aggressive.\u003C/p\u003E\u003Cp class\u003D\u0022MsoNormal\u0022\u003EThey’re not as large as the great white, but female bulls can grow to over 11 feet and weigh up to 500 pounds.\u003C/p\u003E\u003Cp class\u003D\u0022MsoNormal\u0022\u003EThey also have one very special characteristic:\u003C/p\u003E\u003Cp class\u003D\u0022MsoNormal\u0022\u003EMike Heithaus:  “One of the most amazing things about these bull sharks is that they go from marine to freshwater with no problems.”\u003C/p\u003E\u003Cp class\u003D\u0022MsoNormal\u0022\u003EBulls have been found thousands of miles upstream in both the Mississippi and Amazon rivers.\u003C/p\u003E\u003Cp class\u003D\u0022MsoNormal\u0022\u003EThey also are believed to hunt in the same shallow coastal waters where unsuspecting beachgoers frolic in the summer.\u003C/p\u003E\u003Cp class\u003D\u0022MsoNormal\u0022\u003EThey are also opportunistic hunters… they’ll eat just about anything.\u003C/p\u003E\u003Cp class\u003D\u0022MsoNormal\u0022\u003EMike wants to know more about bull sharks and their feeding habits so he’s attached Crittercams to the sharks – underwater cameras equipped with satellite tags.\u003C/p\u003E\u003Cp class\u003D\u0022MsoNormal\u0022\u003EThe Crittercam reveals at least one other bull in the region, which raises the intriguing possibility that these sharks may be interacting.\u003C/p\u003E\u003Cp class\u003D\u0022MsoNormal\u0022\u003EIt also suggests the bull shark may be a keystone species, which means they may be a critical influence on the structure of the ecosystem.\u003C/p\u003E\u003Cp class\u003D\u0022MsoNormal\u0022\u003ESatellite data also confirmed that the bulls stay put, never venturing far from where the team caught them…\u003C/p\u003E\u003Cp class\u003D\u0022MsoNormal\u0022\u003EThat’s more proof that these animals may be an important part of the coastal environment.\u003C/p\u003E\u003Cp class\u003D\u0022MsoNormal\u0022\u003EBut 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.\u003C/p\u003E\u003Cp class\u003D\u0022MsoNormal\u0022\u003EUltimately though, it does us all good to remember that you are more likely to get struck by lightning, than bit by a shark.\u003C/p\u003E",
