When it comes to discharge masters, we first think of electric eels.

In fact, in addition to electric eels, there are many creatures that will discharge.
They are the fish that are active in the ocean and freshwater, and today, let's get to know them!
Electric eel: High voltage line in water
First, let's take a look at the most famous electric eel.
Electric eels living in the Amazon and Guia rivers in South America can release up to 800 volts of voltage, which can be deservedly called "high voltage lines in water". People in the Amazon River in South America often get knocked unconscious by electric eels and drown in the water.
Its discharge range in the water can reach 3-6 meters, stuning animals that are much larger than its own size, such as horses and cows.
The electric eel can generate electricity throughout the body, and almost all the muscle tissue on its body up to 2 meters long can be discharged, and there are thousands of discharge bodies throughout the body.
When generating electricity, each generator releases a voltage of about 0.15 volts, which eventually converges into a powerful voltage of 300-800, and the current flows from the positive electrode of the tail to the negative electrode of the head.
Discharge is a powerful survival weapon for electric eels, which discharge to hunt other fish and aquatic creatures.

Electric Catfish: We learn cat barking together
The electric catfish active in Africa is also responsible for selling cuteness and discharging two stunts, in terms of selling cuteness, it mainly relies on sound, it can make a sound like when a cat is angry.
The electric catfish also grew two small mustaches, so it was given an image alias by humans: "electric cat".
Light energy can not stand in nature, fortunately, the electric catfish's discharge ability is also excellent. Electric catfish rely on the dermal glands under the skin to generate electricity, which contain about 5 million plates. These plates surround the entire body of the catfish and can generate voltages of up to 300-400 volts.
As the most powerful fish in Africa, it also has a violent temper, often turning a fish tank upside down without a word, and may be more like the Pokémon Tyrannosaurus rex in character.

Electric Ray: Undersea electric shocker
Electric rays live in tropical and subtropical offshore waters. Its discharge ability is slightly inferior to the previous two, but it is also enough to resist enemies and prey.
The rays can release a voltage of about 70-80 volts, sometimes up to 100 volts. If a person encounters it in the sea, although it is not fatal, he will be paralyzed by electricity.
The electric ray mainly relies on the honeycomb-shaped generators on the sides of the head and the ventral surface of the chest, the generator is mutated from the muscles of the gills, and the power generation organs are composed of electrical plates composed of fibrous tissue, and about 2400 electrical plates on each side form a communication tube. Current flows from the abdomen to the back.
Eels, flounder, salmon, etc. are all delicious food for electric rays, which will discharge the other party's corona and swallow it whole into the stomach.

Junxingyu: Look at me with a pair of electric eyes
It is a family of 11 genera of the order Rayfinfish, which is divided into 11 genera, and this family of fish is found in all oceans of the world. Their common form is characterized by a large head as large as a cube dragging a flat body.
Their eyes grow on the top of their heads and hide behind them a hair generator derived from the eye muscles. This pair of generators can emit a voltage of about 50 volts, which can be described as a real electric eye.
Naked Buttocks: Electricity is my eyes
The discharge ability of the tropical freshwater fish naked buttocks is not worth mentioning compared to the "big guys" in front of them. The voltage released from its tail is only 3-7 volts, which is not enough to make you feel tingling. But this weak current is an indispensable survival skill for naked buttocks.
Because the naked buttocks fish is a "blind eye", its eyesight is very weak, and it likes to live in a dark environment, so it has to explore the surrounding environment by discharging.
The naked buttocks fish constantly discharges to form a uniform electric field around its body, and when a conductor or insulator appears, it will feel the change in the electric field and react. The current is the eyes of the naked buttocks.

Weevil: Honey, don't discharge me again
The elephant trunk fish living in Africa lie out day and night, and like to stick their heads in the mud to muddy the river, and their eyesight is basically useless.
Its discharge function is similar to that of the naked buttocks, and it emits electrical pulses with a voltage of about 2 volts and a frequency of 300 times per second through the "electric pulse generator" in the skin of the tail, forming a weak electric field around the body to perceive changes in the surrounding environment.

Studies have shown that weevils emit different electrical signals during courtship, mating, and spawning. Through these electrical signals, the weevil uses to judge the physical condition of the opposite sex, genetic conditions and other information, so as to select a high-quality partner.
The love of the weevil fish is really carried out by discharging each other, so it is really weaker than the "discharge" of human love.
After seeing so many fish that can discharge electricity, which do you think is the most powerful?
