But how do you know the fish are sleeping, because their eyes are constantly open?

"Fishery" dream and everything connected with it

Thinking or speaking of a dream, man represents the natural physiological process of the body. When it is the brain does not respond to any minor environmental factors, there is practically no reaction. This phenomenon is also characteristic of birds, insects, mammals and fish.

The third part of his life a person spends in a dream and this is a well-known fact. For such a short period of time a person completely relaxes. During sleep, the muscles are completely relaxed, the heart rate and breathing decrease. This state of the body can be called a period of inaction.

Fish, due to their physiology, are different from the rest of the planet. From this we can conclude that their sleep occurs in a slightly different way.

  1. They can not be 100% off during sleep. It affects their habitat.
  2. In an aquarium or an open pond, an unconscious state does not occur in fish. To some extent, they continue to perceive the world around them even during their rest.
  3. Brain activity in a relaxed state does not change.

According to the above statements, we can conclude that the inhabitants of water bodies do not fall into a deep sleep.

From belonging to a particular type depends on how the fish sleep. Active during the day are fixed at night and vice versa. If the fish is small, it tries to hide in an inconspicuous place during the daytime. When night falls, she comes to life and is looking for something to profit.

How to recognize a sleeping fish

Even if a representative of the water depths envelops sleep, she cannot close her eyes. Fish have no eyelids, so water always cleans the eyes. But such a feature of the eyes does not interfere with their normal rest. It is dark enough at night to quietly enjoy the rest. During the day, the fish chooses quiet places, which are penetrated by the minimum amount of light.

The sleeping representative of the marine fauna simply lies on the water, and the current at this time continues to wash the gills. Some fish try to cling to the leaves and branches of plants. Those who prefer to rest during the day choose a shade from large plants. Others like people lie sideways or belly down to the bottom. The rest prefer to stay in the water column. In the aquarium, its sleeping inhabitants drift and at the same time do not create any movement. The only thing that can be noticed at the same time is a barely visible swaying of the tail and fins. But as soon as the fish felt any influence from the environment, it returns to its normal state with lightning speed. Thus, the fish will be able to save their lives and get away from predators.

Sleepless Night Hunters

Professional fishermen are well aware that catfish or burbot do not sleep at night. They are predators and feed themselves when the sun is hiding. During the day, they gain strength, and at night they go hunting, while moving completely silently. But even such fish like to “arrange” their rest during the day.

An interesting fact is that dolphins never fall asleep. The current mammals were once attributed to fish. Dolphin hemispheres turn off for a while alternately. The first 6 hours and the second. also 6. The remaining time is both in waking state. This natural physiology allows them to always be in a state of activity, and in case of danger to escape from predators.

Favorite places for sleeping fish

During rest, most cold-blooded people remain motionless. They like to sleep in the bottom area. This behavior is characteristic of the majority of large species that live in rivers and lakes. Many argue that all aquatic residents sleep at the bottom, but this is not entirely correct. Ocean fish even during sleep continues to move. This applies to tuna and sharks. This phenomenon is due to the fact that the water all the time should wash their gills. This is a guarantee that they will not die from suffocation. That is why the tuna falls on the water against the stream and rests while continuing to swim.

Sharks do not have a bubble at all. This fact only confirms that these fish must always be in motion. Otherwise, the predator will sink to the bottom during sleep and, in the end, it will simply drown. It sounds funny, but it’s true. In addition, predators do not have special covers on the gills. Water can enter and wash the gills only while driving. The same applies to stingrays. Unlike bony fish, constant movement is, in some way, their salvation. To survive, you need to constantly go somewhere to swim.
