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.
The members of the dogfish family – with their beady eyes and wide mouths – dug in with ruthless abandon, in fact. But surprisingly, this was far from the most frightening thing that the team would discover in the depths below. As the predators continued to feast on the carcass, you see, another creature zoomed in to take the spotlight. And it made a shocking on-screen debut that the researchers will never forget.
