Researchers investigate the carcass of a great white shark that washed up in Westport, Mass., just over the state line from Little Compton, R.I., Saturday Sept. 1, 2012. A Massachusetts marine biologist who examined a 13-foot great white shark carcass found ashore near the Rhode Island state line wasn't able to determine how the shark died, state officials said Sunday. State biologist Greg Skomal performed a necropsy on the 1,500-pound male shark Saturday and found no signs of trauma. (AP Photo/Courtney Sacco)
