The Deep Discoverer craft was 450 metres deep off the coast of South Carolina when it saw a group of sharks in the seabed. The vessel caught 11 sharks eating a swordfish corpse about 2.5 metres-long.

Then, the observers saw on the screen a giant fish swimming with a whole shark gradually engulfed in its mouth.
