The Turritopsis dohrnii is a tiny jellyfish that can age backward. When their survival is threatened by injury or starvation, they will transform themselves into a polyp — an early stage of development. Eventually, the polyps will bloom back into genetically identical jellyfish.
Death will come for us all; however, the T. dohrnii isn't the only animal that can delay it. Several animals continue moving or functioning briefly — after what seems like certain death.
