The clip begins showing a giant golden fish lying dead on the floor of a boat as a man stands over it with a knife.
He begins gutting the creature, making an incision in its stomach with a huge knife before rummaging around and pulling something out.
The tiny black object hits the deck of the vessel but he continues to fish out more and more of them.
As the camera zooms in, viewers are able to make out the shape of dozens of baby turtles, presumably having been eaten by the monster predator.
The clip ends as the man proudly shows off the tragic bounty of dead reptiles, leaving viewers absolutely speechless.
According to Daily Star UK, the video is thought to have been filmed off the coast of Mexico – although the exact species of the fish has yet to be determined.
Almost 40,000 people have now seen the video since it was uploaded to LiveLeak.
“I think this is a Mahi-mahi fish, sometimes we call them dolphin fish,” said one viewer.
“They are absolute gluttons.”
Another wrote: “Absolutely disgusting – those poor turtles!”
