There are many organisms in nature that can generate electricity, including more than 500 kinds of fish that live in water and generate electricity. There is a story about electric fish, which tells that when the first Spaniards arrived in the Americas, in the jungles of the South American continent, there was a very rich treasure land, full of gold. In search of that fabled natural treasure, an expedition led by the Spaniard Disica, led by a local Indian guide, went up the Amazon River and came to the edge of a large swamp. It was the dry season, the swamps had almost dried up, and only a few small ponds in the distance shimmered in the midday sun. When the expedition came to the edge of the small pond, the Indian guide was stunned, his eyes full of fear, and refused to walk through the shallow water. As a last resort, Dihica ordered a Spanish soldier to demonstrate to the Indians to cross the river. The soldier after receiving the order walked into the water without concern, but only a few steps away, as if he had been hit hard by someone, he shouted and fell into the water. Immediately the two companions rushed forward to rescue him, but they were also knocked to the ground by the invisible enemy, lying in the muddy water. The whole team did not dare to act rashly, and after waiting vigilantly for several hours, seeing that there was no movement in the water, the soldiers carefully walked into the water and rescued the three wounded soldiers. After examination by the military doctor, the three of them had already been paralyzed in their feet. After a long time, people learned that the enemy who did not know the truth at that time was the freshwater electric eel.
As the name suggests, electric fish is a fish that can discharge electricity, and the most powerful electric fish at present are as follows: electric eel, electric catfish, electric ray, elephant trunk fish and so on.
Electric eels, the world's largest freshwater fish, weigh up to 20 kilograms, and the voltage it produces is 300-800 volts, which is known as the "high voltage line" in the water. Named one of the "Most Feared Freshwater Animals on Earth" on the National Geographic website. In the muscles on both sides of the tail, there are 6,000 to 10,000 muscle flakes arranged in a regular manner. Each muscle sheet is like a small battery that generates a voltage of 150 millivolts. When nearly 10,000 "small batteries" are connected in series, they can generate voltages of up to hundreds of volts, and the electric shock range in water can reach 3-6 meters.
Electric catfish, also known as electric catfish, electric cat. Fierce and light-afraid, it is mainly active at night. With a body length of 50-60 cm, a maximum weight of 20 kg and a lifespan of up to 10 years, it is a freshwater fish. Electric catfish are discharged through cells in the body that resemble small stacked batteries. When an electric catfish is excited by nerve signals, it can abruptly cause an ion flow through its cell membrane. Electric eels have such cells from beginning to end, like many stacked batteries stacked together. When stimulated, it can instantly emit electricity of 200 to 450 volts.
Electric rays, up to 2 meters long, are marine fish and are common in the Yellow Sea and bohai Sea. Its electrical apparatus is like two flat kidneys, arranged on both sides of the body, which is a honeycomb-like structure composed of hexagonal column cells, which is called an electric plate. Among the two electrical officers of the electric ray, there are a total of 2 million electric plates, and under the control of the nervous system, the electrical officer emits electricity.
In the Congo River Basin of Africa, there is a fish called the weevil fish that lives with crocodiles that chew on the earth, dinosaur fish with thick skin, rogue-like tilapia, and even hard stubble such as crown and nine rooms. Its mouth is slender like an elephant's nose, and it is indeed a bit bitter to survive in the water full of strange powers. The main reason is that there is a power generation organ in its tail that can send out electrical pulses 120 to 300 times per second. These electrical signals are then received by nerve cells in the head to survive by finding food, enemies, and obstacles in the murky water.
Nature's choices leave behind many magical things. What is felt before humans are fully aware of them is mystery and fear. After understanding these natural rules, human beings began to apply them creatively. For example, at the beginning of the 19th century, the Italian physicist Volts designed the world's earliest volt battery based on the electric fish power generation organ as a model. If the power generation organs of electric fish can be successfully imitated, then the power problems of ships and submarines can be well solved.
Quality is all around us, electric fish discharge is the rule that already exists in nature, innovation is based on existing rules, and break some rules to achieve new value.

There are many creatures in nature that can generate electricity, among which there are more than 500 kinds of fish that live in water and can generate electricity. There is a story about the electric fish. When the first Spaniards came to America, there was a rich treasure in the jungles of the South American continent. It was covered with gold. In search of the fabled natural treasure, an expedition led by the Spaniard Dichka, led by a native Indian guide, traveled upstream along the Amazon River to the edge of a large swamp. It was the dry season, and the swamp was almost dry, except for a few distant pools that twinkled in the midday sun. When the expedition came to the edge of the pond, the Indian guide, with a look of horror in his eyes, refused to cross the shallow water. Desica had to order a Spanish soldier to show the Indians how to cross the river. The soldier, who had received his command, walked carelessly down into the water, but after a few steps he fell down with a loud cry, as if he had been struck hard by some one. At once the two companions rushed to his rescue, and were likewise knocked down by the invisible enemy, and lay in the mud and water. The whole army did not dare to act rashly. After several hours of watchful waiting, seeing nothing moving in the water, the soldiers gingerly went into the water and rescued the three wounded soldiers. After examination by military doctors, their feet were paralyzed. It was not until much later that they found the unknown enemy was the freshwater electric eel.
As the name suggests, an electric fish is a fish that can discharge electricity. The most powerful electric fish are electric eels, electric catfish, electric rays, elephant nose fish, and so on.
The electric eel is the largest freshwater fish in the world. It can weigh as much as 20 kilograms and produce a voltage of 300-800 volts, and they are known as the "high voltage line" in water. They are selected as one of the "most feared freshwater animals on Earth" by national Geographic magazine's website. There are 6, 000 to 10, 000 sheets of muscle regularly arranged in the muscles on either side of the tail. Each of their muscles is a small battery that produces 150 millivolts of voltage. When nearly 10,000 "small batteries" are connected, it can produce up to hundreds of volts, and the electric shock in the water can reach up to 6 meters.
Electric catfish are fierce and afraid of light, and live mainly at night. The body length is 50-60 centimeters, the maximum weight is 20 kilograms, the longest life span is 10 years, and it belongs to a kind of freshwater fish. The electric catfish is discharged by cells in the body like small laminated batteries. When the electric catfish is motivated by the nerve signal, the ion flow can pass through its cell membrane. The electric eel has these cells from beginning to end, like many stacked batteries. When stimulated, the power of 200~ 450 volts can be sent instantly.
Electric rays, which can reach up to 2 meters, belong to Marine fishes and are common in the Yellow Sea and Bohai Sea.Its electrical organs are arranged like two flat kidneys on either side of its body, and inside are honeycomb structures of hexagonal cylinder cells called plates. The ray has two million electrical plates in its two organs, which give off electricity under the control of the nervous system.
In Africa's Congo River basin, along with gnarling crocodiles, rough-skinned dinosaur fish, rogue tilapia, and even crown, Nine, there's also a fish called the elephanopithecus. Its mouth is long and slender like an elephant's trunk. It's a bit tough being able to survive in a harsh environment. Thanks to a generator in its tail, it can send out 120 to 300 electrical pulses per second. Nerve cells in the head then pick up the electrical signals and survive by spotting food, enemies and obstacles in the murky water.
Nature's choice has caused many amazing things. Before humans fully recognize them, we experience mystery and fear. After understanding the rules of nature, humans began to use them creatively. For example, in the early 19th century, The Italian physicist Volta, using the electric fish as a model, designed the world's earliest volt battery. If we can successfully mimic the electrical organs of electric fish, then the power problems of ships and submarines can be well solved.
Quality is all around us. Electric fish discharge is an existing rule of nature. Innovation is based on existing rules and breaking some rules to achieve new value.
