When divers attached a dead tuna to the bottom of the ocean and set a camera up in front of it, it sparked a storm of activity.
Not a lot happens in the first few moments of the underwater footage, but once the first deep-sea eel appears on the scene, it's soon joined by more.
Before long, there is a crab and half-a-dozen giant isopods – a kind of super-sized crustacean.
Then, as if a switch has been flicked, it becomes a full-blown feeding frenzy. Ocean sediment clouds the scene as tails swipe and segmented shells scramble for their share of the meal.
Watch the astonishing video to the end and you'll see all that remains of the tuna is a stripped skeleton...
