Modern society has a lot of anxiety and worries, and it is difficult to live in a stressful society. For a change of pace, I go to the aquarium and look at the fluffy jellyfish, which soothes my soul. The slow movements of jellyfish have been scientifically proven to have a healing effect. Jellyfish float gently in the water, calming the hearts of those who watch them. This movement has the effect of making the parasympathetic nervous system dominant and reducing stress. Jellyfish are creatures without brains and do not think, but they have all the functions needed to survive. Its mysterious ecology also attracts people’s interest and curiosity. There are over 3,000 species of jellyfish in the world, and they come in a variety of shapes and colors. When you look at jellyfish, you can experience the wonder and beauty of nature.

By the way, most of the stomach parts have four, but some have three or even five.
