You may have read about mysterious cases of severed feet washing up on beaches in British Columbia. Now forensic scientists have done a simple experiment to show how these things happen. They put a pig carcass underwater and filmed it to demonstrate how quickly ocean life can strip a dead body of all its flesh - causing limbs to fall off in the process. What you're seeing in this video is a large pig being reduced to bones in a matter of days. The body was put into a cage so no sharks or big fish could reach it. All this destruction is just from small sea creatures.

New Scientist has the story:

The pig carcasses are revealing for the first time how different conditions, for example depth and seasonal changes, affect decomposition in seawater. "We have had a lot of disarticulated feet wash up on our shores in running shoes," says [researcher Gail] Anderson. "This work is showing the public how crab and shrimp activity can result in severed limbs and that's it's a normal process."
