5 secrets of jellyfish

Jellyfish are made of 95% water. They look very delicate, but they are also flexible and strong.

How ​​long have jellyfish been on Earth?

Jellyfish are said to have existed for 500 million years. That is long before dinosaurs and ammonites existed. They have existed long before humans were born, and their appearance has hardly changed at all.

Jellyfish change many times

Jellyfish have remained unchanged for hundreds of millions of years. But that is not the case in the life of a jellyfish. They change many times until they become adults. They spend their time on the ocean floor in a sea anemone-like form, or float in the water like a flower petal. Their appearance changes so much that no one would recognize them as jellyfish. After four transformations, they finally take on the form of a jellyfish about 0.4 inches long.

If they feel uncomfortable, they rest and run away

Jellyfish that look like sea anemones shortly after they are born are called "polyp". Polyps grow root-like structures and settle on the ocean floor. However, whether they can remain there or not depends on the environment. If it doesn't suit them, they will cover themselves with a shell and hibernate for a while, or lose their roots and drift away to another location. Then, if they find a suitable spot, they will grow roots again and live there.

The "immortal jellyfish" that revives again and again

The "immortal jellyfish" is a small jellyfish about 0.1 to 0.4 inches in size. It is also said to be an immortal jellyfish that comes back to life again and again. When it is stressed or damaged, it degenerates and loses its original shape, becoming just a round lump and sinking to the bottom of the sea. However, from that lump, something like a bud or root grows. It becomes a "polyp" again, just like when it was just born. It is a very mysterious jellyfish that returns to its baby form and grows again and again.

Jellyfish are creatures that do not "think"

We humans are always thinking and worrying about something. That is why we can create new things and solve problems. On the other hand, jellyfish do not have a brain, so they do not think. They do not think, and do not care if they are swept away by the waves, and are natural. There is no set way to live.

Jellyfish grow by changing their appearance, but not all of them are the same. Some skip the process of growth, and some split along the way to create clones. They also make their bodies smaller when there is little food around, and larger when there is a lot. Apparently they can shrink to a size of just 0.1 inches.

The more you know about jellyfish, the more mysterious they are. And it seems that the way jellyfish live has something important to teach us...

It seems as if the things that never change and the things that keep changing are connected.

Being uniquely oneself seems to be a much simpler matter.

“What is my uniqueness?"

When you are free from thinking that, you may achieve uniqueness.
