Sharks are known for being big eaters, seemingly made to munch any and every thing they can possibly sink their hundreds of razor sharp teeth into.
Seeing as how they're large predators they prefer lots of protein, as in huge quantities of meat, and they apparently have no love for their fellow shark when their stomachs are empty.
Visitors to the South Korean aquarium where this video was shot had no idea they'd be learning a lesson about nature's cruel sense of humor that day, but now they know the aquarium stocks their tanks with the freshest seafood money can buy!
