Sharks and the ocean’s twilight zone: Some female great white sharks can deep dive for hours

Scientists at Woods Hole Oceanographic Institution on Cape Cod are researching the sharks’ deep diving behavior and how sharks’ bodies have evolved to handle these deeper conditions. The mature female great whites will deep dive up to three hours in the twilight zone, he said. Two of the large female great whites have even traveled out into the eastern Atlantic Ocean. Different shark species spend varying lengths of time in the twilight zone. “The more tags we put out, we’re seeing how important the twilight zone is to all of these species.”
