February** Dynamic Incentive Program
Fish, a group of creatures that live in water, also have the need for sleep. When they are sleeping, they will choose to stop swimming and find a quiet corner to settle down. This type of sleep is similar to a short nap in humans in that it is not long, and they wake up quickly as soon as there is an external stimulus. This trait is not only found in fish, but also in other lower vertebrates.
If they remain motionless at the bottom of the water, the only thing they can see is that the cheeks are gently opening and closing, then the fish are enjoying their sleep at this time. Because fish have no eyelids and eyelids on the outside of their eyes, when sleeping, they cannot close their eyes like humans, and can only fall asleep with their eyes wide open.
This way fish sleep makes us marvel at the wonders of nature. In nature, all kinds of organisms have their own unique ways of living and habits, and this is part of biodiversity. Although fish can't close their eyes like humans, they are still able to sense their surroundings in other ways and ensure their safety.
The resting state of fish during sleep also provides an opportunity to observe their habits. In this way, we can better understand these aquatic creatures and further study their habits and behaviors. This will also help us to better protect and care for these creatures, maintain ecological balance, and make nature more harmonious.
In short, fish sleep, although they cannot close their eyes like humans. This unique way of sleeping allows us to learn more about these creatures that live in the water and also makes us more in awe of the wonders of nature.
