Description
Elinor Nadir, Vyctoria Marillac, Tamar Lotan and Yehuda Benayahu test the regenerative powers of a soft coral, Xenia umbellata, in a 2026 study. Jellyfish relatives are famous regrowers. Yet whole-body regeneration in colonial octocorals, as opposed to solitary polyps, had barely been studied. It may still fuel this species' spread into new seas.
Fragments of tentacle or polyp body as small as a tenth of a square millimetre rebuilt complete, working polyps. Both routes passed through a ball-of-tissue stage. Tentacle pieces first had to erase their specialised structures and grow new internal partitions, while body pieces reorganised faster. Cutting off both ends showed the fragments could also re-establish which end is which.
