when jellygirls get injured or lose a limb they can pretty quickly grow new tissue, to regenerate the symmetry and balance of their body.
from the cut off body part a new jellygirl will form, just in case the original’s mesoglea couldn't heal itself properly.
having an exact copy of them
selves around usually makes the original jellygirl feel uncom-
fortable .
and so they usually end up annihilating their replica, sometimes they even eat the corpse
or just eat the severed body part before it could grow into a fully developed jellygirl.
