A large, predatory shark swimming near Bermuda was gobbled up by an even bigger shark — even swallowing the tracking device that was attached to it — in what scientists say is the first recorded case of its kind.
Porbeagle sharks (Lamna nasus) can grow to about 12 feet (3.6 meters) long. These large sharks patrol the Northern Atlantic Ocean as well as parts of the oceans of the Southern Hemisphere, ranging into the Antarctic. Their muscular, streamlined forms and angled, spear-like teeth make them formidable predators. But the porbeagle, it seems, is not immune to predation itself.
