electric ray
This torpedo looks very strange, with a flat back, a mouth in the abdomen and a nearly round body plate. It looks like a cattail leaf fan, and generally inhabits the bottom of the sea. The maximum length can reach 2 meters, and there are several kinds of torpedoes. Different kinds of torpedoes can generate 40 to 220 volts, and the instantaneous current can reach 50 amps, which can instantly paralyze the human body.
There are two generators in the belly of the torpedo. How many beehive generators are there? Electric plate? The electric plate is connected with the nerve endings. Under the control of the nervous system, the torpedo can store the nerve energy as electric energy, and the colloidal substance between the plates plays an insulating role. The dry battery we use was originally invented by torpedo.
The torpedo discharges through the tail, and the discharge time and intensity can be accurately controlled. The number of discharges per second can reach 50 times, which is enough to prey on some small fish and shrimp. After discharging for more than ten seconds, there will be no electricity, and it will take some time to return to normal.
In addition, when the generator of the torpedo stores electric energy, it will form a weak electric field around the body, and then the torpedo will perceive the surrounding environment through the change of the electric field through special cells, so the torpedo can move in an environment without light at all.
Electric catfish
The electric catfish mainly lives in tropical Africa, and its body length can reach 1 m. Its mouth has three pairs of beards, which are very conspicuous and similar in size to catfish. Electric catfish, on the other hand, has no dorsal fin, and can generate a high voltage of 450v at most, which can corona people.
Unlike ray, catfish? Electric plate? It is distributed between the skin and muscles of the body. The head is positive and the tail is negative. There are about 5 million plates in all. Single board can generate very weak voltage, and the voltage is very high after series connection.
When the electric catfish's body is fully charged, any part of the body touches other objects (including prey and enemies), which will lead to the release of current. The high voltage of 450v is enough to make adults dizzy.
Amazon electric snake
A snake living at the mouth of the Amazon River can also discharge electricity. Is that what the locals call it? Electric snake? The length of the electric snake can reach 2 meters, and the voltage is as high as 650V, which can make hippos jump in the river, and the electric energy reserve is amazing.
The locals even put the captured electric snakes in cages, then tied them with ropes and threw them into the river. One person pulls the cage in front and the other person pulls the net bag in the back, so that the electric snake can stun other fish and fall into the net bag.
Zhanxing fish
Starfish has a huge mouth and grows upward. This is because they like to bury their bodies in the sand at the bottom of the sea, then expose their eyes and mouths and use the racket in their mouths to lure small fish.
If you encounter a slightly larger fish, the starfish will release a voltage of about 50V and then stun the prey. His discharge organs are located behind the eyes, and they are two in one.
Naked buttock fish
Nickname? Nile devil? With a body length of 1.5 meters, it has a unique dorsal fin, which basically runs through the whole body and has a beautiful posture when swimming, so it is also an ornamental fish.
The naked waist fish looks docile on the surface, but in fact, just like its nickname Nile devil, it is extremely fierce, and its powerful jaw can bite off other small fish in an instant. Once other fish get close to it, it will show its ferocious side.
Unlike other discharge fish, naked fish are not used to attack prey. The eyesight of naked fish is seriously degraded. It relies on the tail muscles to release a weak current, and then senses and locates its prey. It is a nocturnal creature, mainly living in some muddy basins in Africa.
Elephant trunk fish
A fish that lives in Congo, Africa, is 20~50 cm long and fierce, and looks like a knife. Its jaw is slender and tubular, which can be used to find food, hence the name elephant trunk fish.
The tail of the elephant trunk fish can send out continuous electric pulses. Elephant trunk fish can sensitively perceive the weak changes of electric pulses, and it is by virtue of the signals of electric pulses that they can judge the surrounding environment. So, like trunk fish and naked fish, its discharge function is used to enhance environmental perception.
Blunt swordfish
Swordfish is a new Amazon fish discovered by scientists on 20 13. The power generation organ is located at the tail, which can only generate electrical pulses of several hundred millivolts, and is also used to enhance environmental perception.
electric eel
Electric eels can generate high pressure of 300~800. Nickname? High-voltage line in water? , is the highest release voltage of all living things, mainly living in South America, with a body length of 2.5 meters and slow movement.
The muscles on both sides of the tail of the electric eel are relatively thin, and each piece can generate a voltage of about 150mV. This kind of muscle is about 5000~ 10000, and the whole body is like a big battery. After being connected in series, it can generate high voltage as high as 800V, which is enough to stun a crocodile or a cow, but the duration is not long (10.
Electric eels can control the time and intensity of their own discharge. The average discharge voltage is 350V, and the current does not exceed ampere. If a person is knocked down by an electric eel in the wild, he may not die immediately, but he may fall into the water and drown after being knocked unconscious.
