Creepy, cool, gross, or all three?
Researchers have discovered two species of sea slugs that can cut off their own heads and then grow new bodies.
A study published Monday in Current Biology details the findings.
About a third of one of the slug species the researchers studied began to self-decapitate less than a year after hatching.
After 20 days, those slugs had regenerated their entire bodies.
It's not clear why these slugs go through the process.
