I am an animal person. I specially love dogs but with two kids and great grandmother. I can’t take responsibility of one more baby. As they also need proper care and have lot of responsibilities. I have thought of having a dog but not now, Until my kids grow.
Every time I go to my mom’s house Aquarium with fishes and tortoise fascinate me. In this summer vacation I bought one Aquarium. My daughter was very fond of fishes and take care of them very well. She has taken responsibility of feeding them. She brought out a brain storming question – How do the fish sleep?
Tell me how many know the answer of this?

How do the fish sleep?

How do fish sleep

Fish are living beings that still fascinate people today because of their strange customs. One of them is his way of sleeping. You know that life is originated in the sea, so rare that it should be you. Have you ever wondered how the fish sleep? Well, in this article you are explained how fish sleeps.

Do fish sleep like people?

If the question that concerns you is whether the fish sleep the same way as you do or not, we’re going to explain that, like human beings, these vertebrate beings need adequate sleep. As fish do not have eyelids and their eyes are moist, it is consider that they do not sleep, however they do so in order to protect themselves and conserve their energy. The fish have a membrane that covers their eyes, preventing the dim light of the night from disturbing their “sleep”.

The dream of the fish:

How do fish sleep

The fish never close their eyes and this is only due to an anatomical feature, since they do not have eyelids. All animals, from unicellular organisms to more evolved ones like humans, need to sleep. This is the moment of neuronal rest in which the energies are charged to be able to continue with the day to day. Therefore, fish are not less and also sleep, but in a very different way than humans. In most fish, your rest consists of stopping swimming and reducing your physical and metabolic activity, staying in some corner, between the rocks or in more sheltered areas dozing. It is more a state of rest than a deep sleep like that of humans. But it has the same result.

Each fish has its technique to sleep:

Some fish rest by putting their rear or bottom fin on the seabed as an anchor so they cannot be washed away by the marine current. Others make strange noises to scare away possible predators (as in the case of the snoring fish). Another technique of rest that some fish use is to let themselves fall on the seabed and thanks to their swim bladder to be able to raise to breathe and return to descend to the bottom without waking up (yes, although it sounds incredible).

In the case of dolphins and whales (mammals) they can use two techniques, depending on whether they are accompanied or go alone. In case of going alone, they will stay still as if they were a trunk; and in case of being accompanied, one of them will act as a guide and the others will swim slowly with him.

In the case of sharks, having no swim bladder, they will not be able to go up and down to breathe, so they will have to be in constant movement to be able to breathe (thanks to the gills and oxygen in the sea). If a shark stops, it runs the risk of going to the bottom and dying. Therefore, as a conclusion, it can be said that the fish do sleep, but each one does it their own way.
