NOAA wrote in a statement: “Using the ROV for cover, the wreckfish demonstrated the ability of large predatory fishes to feed on smaller sharks.
“The wreckfish appears unable to feed on the swordfish directly itself, but by joining the sharks, it was able to feed on an animal that was. “
NOAA believe the school of sharks, which are not normally found in groups, must have been drawn to the swordfish carcass “from a distance”.
They added: “Normally we don’t see any deep-sea sharks in a group or aggregation, unless there is some nearby patch of food.
