Sea slug adaptations - body regeneration

 

Elysia marginata

 

Two species of sea slug from the order Sacoglossa, Elysia atroviridis and Elysia marginata, are able to completely regenerate their bodies - including heart, kidney, intestine and reproductive organs.

The head can survive for up to a month, surviving autonomously thanks to its ability to photosynthesize like plants.

Pretty amazing!
