Why is Turritopsis dohrnii called the immortal jellyfish?

The Mediterranean Sea holds a wonder that beats all – something that never dies! It is a jellyfish whose scientific name is Turritopsis dohrnii.

Jellyfish start their lives as larvae, which attach themselves to a suitable place like a rock. Then they are transformed into polyps that have a small body with tentacles. These polyps then clone themselves to form others and create a colony, or a medusa, which is the jellyfish.

When this jellyfish dies, or is physically damaged, the decaying cells form new polyps, and later return to their jellyfish state. This way they could live forever under the right conditions! However, they don’t actually achieve immortality because these tiny wonders are eaten by fish or other animals, or die by other means.

Although the jellyfish has ‘fish’ in its name, it is not fish. It is not made of jelly either. Unlike a fish, it is an animal without a backbone found in oceans and seas around the world. The name jellyfish derives from the jelly-like bodies of these animals. Jellyfish are found in oceans and seas all over the world, in the deepest as well as in shallow water.
