Guillotines might. Missing from the social media discussion of these is that this only happened to young sea slugs. Older ones just died after some days, and did not regenerate their bodies.

So the middle-aged sea slug oligarch/monarch, sitting all green on xyr emerald seaweed throne, is not as safe from the French Revolution as xe might think.

I suppose that now you have an excuse to use '#kleptoplasty' and '#autotomy' in a story. (-:

’Solar-powered sea slugs’ are able detach their heads and regenerate a whole new body within weeks - BBC Science Focus Magazine

The finding is an extreme example of autotomy – an animal’s ability to shed a body part when under threat.

A single peptide helps starfish get rid of a limb when attacked

A signaling molecule that's so potent injected animals may drop more than one limb.

Scientists discover how #starfish get ‘legless’
A neurohormone that makes their arms fall off is identified

I just learned that #autotomy is the ability to shed a limb - don't try this at home!

Scientists discover how starfish get ‘legless’

Researchers at Queen Mary University of London have made a groundbreaking discovery about how starfish manage to survive predatory attacks by shedding their own limbs. The team has identified a neurohormone responsible for triggering this remarkable feat of self-preservation.

An inspiring interview of the Belgian musician #CélineGillain, about her new album Mind is Mud.

Extreme self-decapitation in sea-slug: the head part is able to regenerate full body including functional heart and kidney in 20 days. It is a possible adaptive response to endoparasite infesting the body part. #science #biology #autotomy #gastropod #mollusc #seaslug #beheading #parasite
