Something was killing these “invincible” sharks, hidden cameras found THIS camouflaged culprit

A giant aquarium was the home to a wide variety of species, including a few predators. The researchers believed that the octopi could hide or defend themselves against the sharks, who have been known to make a quick meal of the 8 limbed cephalopods. They couldn’t believe it when bodies of the sharks kept showing up on the tank floor. After setting up some cameras they found the giant octopi were more than capable of defending themselves, they would outright attack the sharks to eliminate the threat.
