A fish living in Australia is called "Almighty Mouth". As the name suggests, this fish has a big mouth. They don't even need to chase their prey, as long as they lurk in the underwater plants and wait for the prey to approach, they can swallow it.

However, if you use it to swallow food, your mouth cannot be called all -round. And another function of these fish mouths is to raise children.

Not only can it be used to eat, but it can also be used to raise children's mouths. | scitechinstitute.org

Raising children with the mouth is a kind of survival strategy in nature. For the safety of the baby, some fish will contain the undead fish eggs in their mouths, waiting for the small fish to hatch and can be released when they can swim. If you encounter danger, small fish can also return to the parents' mouth.

However, although the survival rate of small fish is raised, this is still a difficult job, because the pressure is given to the parents. Putting the fertilized eggs into the mouth means that you ca n’t eat good things. When the cichlid mother hatchs eggs with his mouth, it often eats less rice, causing mothers and small fish to be malnourished.

The greater threat is still behind. In order to reduce their incubation pressure, parents will also mix their eggs into cichlid eggs in order to reduce their incubation pressure and let the cichlid mother help hatch without knowing it! The hatching small catfish treats their adopted mother, and they are not polite, they will eat unqualified cichlid eggs. Let the difficult incubation work worse, and in other fish, the professional fish father took the job.

Because the cuckoo also parasites its eggs in other bird nests, this fish is named "azalea catfish". | Wiki

The "all -round mouth" father mentioned above is one of the dedicated fish. The name of this fish is Glossamia Aprion. When the egg is fertilized, the fish father will collect them with his mouth and hatch in his mouth.

In a recent study, researchers carefully observed these dads who are "eloquent".

The eggs of the tongue can be hatched for 2 to 3 weeks. Oral cultivation can ensure the safety of juvenile fish, but it is necessary to sacrifice parents' feeding, health status and digestive breathing ability. Studies show that when the father of the fish is in the mouth, they do not eat at all. Scientists found that almost all these dads were empty.

The mouth is full of offspring not only causes breathing difficulties, but also causes the rate of fish to slow down. This means that it is difficult to escape when the father of fish is in danger.

Really bullying fish!

Since raising children is so difficult, the fish father is still so dedicated. People used to speculate before that this is because these fish dads are more loyal and follow the monogamy in the fish world. However, after checking the little fish in the mouth of the fish, the researchers had a new strange discovery.

They chose two kinds of father who was cultivating: Ge's Xinhaibia and Tongti Rarn, and took out some fertilized eggs from their mouths and began to analyze these fish eggs DNA.

It was found that Ge's Xinhaiyu was indeed very loyal! Ge's new Haiyu's father's mouth is 100%of his own children. However, ... the tongue and the dad of the tongue is not the case, the situation was very complicated.

Researchers use diagrams to explain this. The breeding of the tongue can be divided into four cases. There are children who have a wife in their mouths, a polygamy, a long -time wife, and even a child who has no blood relationship with their parents.

Researchers proposed that when males and females paired, some eggs of female fish may have been refined by other males, but they are still included in the mouth of this fish father.

There is also a situation: When the fish father hatched the small fish in his mouth, he got a new mating opportunity. In this case, they would eat some of the old fertilized eggs in their mouths directly, and get new mating opportunities to get new mating opportunities Essence

Other fish dads may adopt fish eggs abandoned by their parents, raising small fish without blood.

These little -known parent -child models are very peculiar, and even researchers cannot make conclusions. However, for these fish, they may look strange behaviors, perhaps to improve the success rate of reproduction.
