Come on. It's for science.
In fact, it's meant to help people.
Researchers at Simon Fraser University in Burnaby, British Columbia, Canada, put a dead pig in a shark-proof (and octopus-proof, as you'll see) cage and stuck it in the ocean in order to learn more about how human remains decompose underwater. That knowledge will help forensic scientists interpret crime scenes.
Most of the work is done by maggots known as sea lice, but towards the end, after the maggots have eaten the good bits, you can watch some fat, red shrimp move in to pick apart the cartilage.
