On the inner side of the pectoral fin of the electric ray there is an energy-generating organ converted from muscle. It is made of electrical plates made up of many special tubular cells. Each tubular cell is insulated by a layer of gelatinous material. One side of the electrical board is smooth, with nerve endings distributed as the positive electrode, and the other side is uneven, without nerve endings distributed as the negative electrode. This structure is very similar to a battery. Whenever the electric ray is attacked by an enemy or finds food like small fish, it transmits shock commands through the nerves and forms a 60-80 volt electric field in the water to repel enemies or capture food.
Fish that can generate electricity and emit radio waves.
In the fish kingdom, there is a type of fish that can ggenerate electricity or emit radio waves. Their methods of hunting and defending against enemies are very intelligent.
In the vast ocean lives the electric ray which can generate electricity. Its generator is a mutation of the branchial muscles. On the back of the head and inside the pectoral fins of the shoulders is a large oval honeycomb-shaped generator on the left and right sides. The most fundamental structure of every energy-generating organ is a small plate - an electrical plate (fibrous tissue). About 40 electric plates overlap from top to bottom to form hexagonal columnar tubes. There are 600 tubes on each side, called electrical plates. management. It is filled with colloid, so it appears translucent and milky white to the naked eye, which is obviously different from the surrounding pink muscles. The side of each electrical plate with the nerve endings is the negative electrodeand the other side is the positive electrode. The direction of the current is from the abdomen to the back. The discharge amount is 70 to 80 volts, sometimes reaching 100 volts. the discharge is 150 times per second. When people dissected the electric ray, they found complete eels, flounder, and salmon in its stomach, because the electric ray stunned active fish with an electric shock and then swallowed them. This is why electric rays are known as “underwater electric shocks”.
In addition to electric rays, thorn rays, star rays, Ho rays, Chinese fan rays, etc. all have weak energy-generating organs. The starfish generator is located behind the eyes, oval in shape, and can generate up to 50 volts. And electric eels.
