VINEYARD HAVEN, Mass. (AP) — Lewis Pugh has followed an unspoken rule during his career as one of the world’s most daring endurance swimmers: Don’t talk about sharks. But he plans to break that this week on a swim around Martha’s Vineyard, where “ Jaws” was filmed 50 years ago.

Lewis Pugh has started swimming around Martha’s Vineyard, where “Jaws” was filmed, as white sharks return to the region to feast on seals. Pugh in his 60-mile swim is trying to raise awareness about the slaughter of sharks worldwide, and its effect on ocean ecosystems.
