Lighthouses and fried clams are as popular as ever on Cape Cod this summer, but they’re sharing top billing with a surprise attraction: sharks. While skittish swimmers may be less inclined to go for a dip in the ocean following an apparent great white shark attack in Truro this week, officials and business owners say the publicity is boosting revenue.

“Anything that brings people to town is good for tourism, and the sharks are bringing people to town,” said Lisa Franz, executive director of the Chatham Chamber of Commerce, where there have been an increasing number of shark sightings over the past few summers.
