The Nara Women’s University of Japan has a vast collection of Sea Slugs. It was noticed that on occasion the body of a sea slug would be lying next to its severed head. What was strange was the severed head was still moving around the tank and still munching on algae. What was determined by the scientists was that sea slugs will decapitate themselves if they feel their body has become infected by a parasite. The head wound took about a day to heal and a new heart about 3 days to grow. However, there was no new growth on the severed body, but it did react to stimuli for months before finally decomposing. Too bad Marie Antoinette wasn’t part sea slug.
