What is the name of the organ of balance in jellyfish?

Jellyfish are rightfully considered one of the most ancient living organisms on Earth. The jellyfish or jellyfish generation is a phase of the eaters life cycle. A closer look at the anatomy of jellyfish, we can find that their nervous system is very well developed.It is worth noting that jellyfish do not have a brain that regulates all processes in living organisms.
Very interesting is the fact that jellyfish keep their balance in the sea. If you turn the jellyfish down, then at the edges of the umbrella we will see a formation called the edge body. It contains the organs of balance of the jellyfish – statocysts. By their nature, they are mechanoreceptors. With the help of statocysts, jellyfish recognize sound waves from 3 to 12 Hz. It is the sound waves that irritate statocysts. Recognizing the danger, the jellyfish swims away to the depths of the sea.
Thus, we can conclude that the structure of this or that part of the body is directly related to the function it performs.
