Way out in the deep blue sea, there is a remarkable creature called the immortal jellyfish. This buoyant little blob can deal with being hurt or stressed by going from its adult form back to a baby!! Then it grows up all over again. Holy moly. How does that work? We asked science writer Christina Couch to tell us all about it. 


Got a question that’s a ten out of TENtacles? Send it to us at BrainsOn.org/contact, ‘cause we are READY for that jelly!
