Absolutely all living things need oxygen. They can take it from the air or water.
But how do fish breathe? They have no organs as complex as their lungs.
But the fish have gills. They help to absorb this gas when breathing.
At the same time, they function much more efficiently than our lungs, because they are able to take up to 30% of the oxygen dissolved in it from the water. But in reality, the ways of breathing in fish is much more.
All of them evolved as a result of a long evolution and are inherent only to certain species.
Many aquarium owners have noticed how fish breathe. They often swim up to the surface of the water and stick their heads out a little.
What are they doing this for?
Many species of aquarium fish have a specific respiratory organ – a labyrinth. With it, they can actually absorb oxygen not from water, but from atmospheric air.
At the same time, the fish should rise to the surface at least once every few hours and take a breath. Otherwise, she will die.
Gill labyrinth is located on both sides of the fish head. It is located above the gills.
When a fish swallows a bubble of air, it falls into the spongy chamber of the maze. Their walls are densely covered with capillaries. Oxygen penetrates into them, which is then carried to all organs and tissues of the body.
Gill maze helps fish not only survive in an oxygen-depleted body of water, but also move to another.

Fish in a dream are those people who are trying to find a way out of a difficult situation and improve their lives. But if in a dream a person is left without a catch, all his efforts will be fruitless.
If the dream included fishing gear — a net, hooks, or a drag — then the future well-being depends on their integrity. Strong nets and hooks dream to a happy end of affairs, torn and rusty – to failure.
In the old days, people often thought that a fish dreams if a person is doing something difficult and useless (“beating like a fish on ice”) or he should think carefully before saying something (“keep silent like a fish”).
Sigmund Freud believed that dreams betray the hidden desires of man. The fish, in his opinion, dreams of people who often dream of sex.
