The marine photographer who captured the footage said it could be the world's first recorded sighting of a black seadevil ...

A scary-looking creature with “devil” in its name was spotted close to the surface off Tenerife, a Spanish island.

The deep-sea dragonfish ... pitch black, cold and under immense pressure, making it one of the most extreme environments on Earth. But none of that is a problem for these ferocious fish!
