The immortal jellyfish

Have you heard of the immortal jellyfish? When in an emergency situation (like starvation, physical damage or other crises) this curious creature can transform from an adult to a blob like cyst which then develops into a polyp colony (essentially the first stage in jellyfish life)! About as wide as your pinky nail when fully grown, the immortal jellyfish was discovered in the Mediterranean Sea in 1883. But its unique ability was not discovered until the 1990s. The jellyfish’s cells are often completely transformed in the process. Muscle cells can become nerve cells or even sperm or eggs. Through asexual reproduction, the polyp colony can spawn hundreds of genetically identical jellyfish—near perfect copies of the original adult!
