Great white sharks have found a new home off the shores of Nova Scotia, Canada. With the waters now frothing with great whites, interactions with humans are on the rise. A team of scientists tracks down and tags the biggest sharks to uncover the sharkiest locations before there's a fatal attack.   

When Shark Tagger Keith Poe saw the shark for the first time, he knew it was different. It was aggressive, 13-feet long and had very dark skin. Now, a group of experts lure the beast up from the abyss to determine if the creature is a mako, or mutant, or possibly, a mako and great white hybrid.
