I believe that the friends living in the countryside have seen the scene of fishing with electricity, and people carry the battery to catch them by discharging corona fish in the water.
But in the Amazon basin of South America, it is the opposite, there is a kind of fish that can be discharged, and any creature that comes close to it will be coronaed by it, and then it will be eaten, it is the Amazon bully - electric eel.
Electric eels are eels of the family Naked-backed Electric Eels, Latin for Electrophorus electricus. It is called a bully in the water because it can release a voltage of 300-800 volts, and can kill all the creatures around it, even piranhas and crocodiles dare not go near it.
Electric eels have no natural enemies in the water, the only natural enemies are humans, which causes it to be unscrupulous and unscrupulous in the water, just like the domineering brother in the TV series. When hungry, it will electrocute the small fish and shrimp, and then eat a big meal, because too many people who are electrocuted can't finish eating, and it will call on its companions to come and enjoy it together.
Although the electric eel is a freshwater creature, it grows in the sea, and the male electric eel and the female electric eel are still in a long-distance relationship, and they will only meet when mating, and will be separated again after mating (and human long-distance love is like ah)
Male electric eels are very lazy and bear little responsibility for breeding the next generation, just waiting in the river for the female to find them.
Female electric eels are much more industrious, and the gonads of female electric eels can only mature in the seawater, so they must swim from the sea to the river when they mature, and then return to the sea to lay eggs after mating with the male (the mother loves great, the male electric eel sows a seed).
Female electric eels can produce 7-10 million eggs at a time, hatch into small fish in 10 days, and then swim into the river again.
So how do electric eels discharge?
Four-fifths of the muscles of the electric eel can store electrical energy, just like the batteries of new energy vehicles. Numerous small batteries make up a large battery, and the tail muscles are generators that are used to generate electricity. Electric eel discharge also has a positive and negative pole, the head is the negative pole, and the tail is the positive pole. The dry battery common in our lives was invented through the electric eel.
Many people, including me, also have a doubt before, whether the electric eel discharge will be electric to themselves, in fact, it will not. Because the surface skin of the electric eel has a layer of fat, it can isolate the current, of course, if the skin breaks the muscle, it will be electrically transmitted.
Electric eels can not only be simply discharged, it can even control the intensity of the current, the strength of the voltage. The voltage that electric eels can release will become stronger with the growth of the body, and can be released an average of 30-50 times per minute, and can be charged after the power is used, and can also be charged while using, which is more than the battery cattle invented by humans.
Although the electric eel is the overlord of the water and has no natural enemies, but all things are in harmony with each other, there is no need to fear that the electric eel will flood, after all, there are still human beings as foodies.
Perhaps in the near future, human invention can go beyond the battery created by the principle of electric eel discharge, and further make society more inclined to technological development.
