New data shows that great white sharks are spending more time in the chilly waters off New England and Atlantic Canada. That means boaters, beachgoers and fishermen who spend time in the northern waters are learning to live with the sharks made famous 50 years ago by the movie Jaws. Sightings of the apex predators are up in places like Maine, where they were once very rarely spotted. Scientists link the white shark sightings to increased availability of the seals the sharks feast on, and say beachgoers are generally very safe from shark bites.
