A research team such as the California Institute of Technology said on Thursday that the jellyfish who is in the tropical ocean, for example, is in a state of drowsiness and sleeping at night. Sleep is a physiological phenomenon common not only to animals such as mammals but also to insects and the like, and it has been thought that there is a purpose mainly to rest the brain. There is no central nervous system such as the brain, even more primitive jellyfish has been confirmed that the common theory seems to cover.
A paper was published in the American magazine "Current Biology". The research team kept observing 23 fellows of Sakasakurage who live on the sea floor with their tentacles facing up through day and night for 6 days. As a result, the action of opening and closing the umbrella part was 1155 times per 20 minutes during the day, while it was 781 times at the night, about 30% less.
When you measure the time to lift the jellyfish at the bottom of the aquarium and return to the bottom, you usually swim and return to the bottom immediately, but if you are in a sleeping state, after 5 seconds of drifting, you suddenly awakened to the bottom as you awoke I started swimming towards it. Even once every 20 minutes, I also confirmed that if I make stimulus so that I can not make jellyfish sleep, I will fall asleep immediately even during the day. I judged that I was asleep.
Michael Abrams, a graduate student of the research team says, "Sleep suggests that it is an action that has been inherited from the ancient irrespective of the brain." In the future, I am aiming to clarify the function of genes controlling sleeping in jellyfish, whether there are sleeping states in other jellyfish, and so on. (Tetsu Kobayashi)

Regardless of the presence or absence of the central nervous system, since it is established as a single creature, there is a mechanism to integrate it.
Is it not only the difference whether processing is done collectively on the server, or whether individual machines process and cooperate?

Although it is thought that if there is no central nervous system, control of the whole body will not be done
When we look at the phenomenon, the control of the whole body is carried out integratedly even in the sporadic nervous system
I think that it may be possible to capture the method of controlling the scattered nervous system by having a plurality of centers and keeping in contact with each other

In the night phytoplankton did not photosynthesize and was inactive (dispersed from the sea surface which was gathered).Zooplankton is also closed. Jellyfish has reduced the amount of activity as the trapping rate of plankton decreases.

Supplies jellyfish plankton
※ Plankton explodes on the sea surface at noon and its density is high. Jellyfish feeding plankton is swimming and eating hard.
In the night, the plankton diffuses and the density decreases, so the collection rate of food decreases. We are reducing the opening and closing of the umbrella to suppress wasteful energy consumption.

Sleep is said to mainly rest the brain, but of course it is not only to rest the brain
It is rather rather wonderful how we made the theory that it would not go to sleep because there is no brain
