Almost 1,500 feet below the surface, researchers are filming the Atlantic Ocean seabed using a Remotely Operated Vehicle (ROV). Yet in among the harmless fish, coral and sponges, something far more sinister is lurking. And as the team watch a school of sharks feasting on a swordfish carcass, a mysterious creature makes its deadly move.
The researchers had been exploring the ocean floor for 45 long minutes, watching live images beamed from the ROV. But then they stumbled upon a fresh carcass – one that drew creatures from far and wide to feast upon its flesh. And while fish, eels and crabs had all got involved, a band of sharks was really dominating the feeding frenzy.
