We just learned about the Lion's Mane Jellyfish.
Another type of jellyfish is the Immortal Jellyfish, also called the turritopsis dohrnii.
This type of jellyfish does not get very big, less than one inch when it is fully grown.
This jellyfish starts out as a tiny baby jellyfish on the ocean floor.
When it grows up, it turns into a little bigger jellyfish and swims around the ocean looking for food.
If it gets hurt or is starving too badly, it can actually turn back into a baby jellyfish and start all over on the ocean floor!
That's like a grown up human turning back into a baby and starting life all over!
Because these jellyfish could do this over and over forever, they are called the immortal jellyfish, because immortal means you live forever.
