TRURO, MA - AUGUST 12: A 'Recent Shark Sighting' sign is seen near where a colony of several hundred seals often rest on a sandbar at High Head Beach on Cape Cod on August 12, 2012 in Truro, Massachusetts. A man was confirmed to have been bitten by a great white shark less than two weeks ago in the ocean near the shoreline of Truro in Cape Cod. An increase in the seal population on Cape Cod has led to increased shark sightings including great whites. (Photo by Mario Tama/Getty Images)
