Animal game “play” master

In the middle and late 19th century, human society entered the electrical age. Since then, people’s lives are almost inseparable from electricity. Especially today, mobile phones, computers and other electronic products are popular. Power outages for 5 minutes may be unbearable.

In fact, in the animal world, some animals are as inseparable from humans as today’s human beings.

Magical sixth sense

Some animals have super powers, and electrical signals are their sixth sense, which they can use to search for food.

The platypus is one of the species with this ability. The platypus is a miraculous animal that existed 25 million years ago and is known as the “living fossil”. As a mammal, it breeds by spawning. It has a duck-like mouth but a beaver’s body. tail. This animal is so strange that in the 18th century, when a British zoologist George Shaw received a specimen of a platypus, he thought it was a prank. I don’t know which boring person sewed the duck’s mouth to the beaver. . Later, after identification, it was confirmed that this was a real animal specimen, and the platypus began to enter people’s field of vision.

The platypus is a semi-aquatic animal that lives in rivers and lakes for most of the time. When looking for food at the bottom of the water, the platypus uses the mouth to dig up the mud at the bottom of the water. At this time, it closes its eyes, closes the ears and nostrils, and can’t see, hear, or smell. How does the platypus find food? It relies on the sixth sense. The researchers analyzed the mouth of the platypus and found that the structure of the duckbill is of great use. There are more than 4,000 electrical signal receptors on it. The receptors receive weak electrical signals from other animal movements, and the platypus can accurately locate the prey. As if carrying a radar positioning system with you.

In addition to the platypus, mammals that can feel the electric field and Guyana dolphins. Dolphins generally rely on echolocation to hunt. Echolocation is very helpful for finding distant prey, but close-range positioning is its short board.

The Guyana dolphins have their own solution – the sixth sense. When the Guyana dolphins are still in their mother’s stomach, there are some tentacles on their foreheads. After birth, these tentacles gradually fall off. After the tentacles fall off, the dolphins have some depressions on their foreheads. These small depressions are not the cockroaches on the smooth skin of the dolphins. They are the electrical signal receptors of the dolphins of Guyana. When you feel the electrical signals from the swimming fish and shrimp, the nerves transmit information to the brains of the Guyana dolphins, and “draw” a detailed map of the map in its brain.

Sharks are also one of the capable. The shark’s sense of smell is very sensitive. A small spoonful of blood is poured into a swimming pool and it can smell. But the ability of the shark is not limited to this. Like the platypus and the Guyana dolphins, the shark also has a magical sixth sense.

At the head of the shark, there is an electric susceptor that can detect weak currents, called “Laurun’s ampulla”. There are many thin tubes filled with paste in the ampulla, and one end of the thin tube is connected to the opening on the skin. One end is connected to the sac inside the ampulla. In the dirty waters or in the dark deep sea, the “Laurent’s ampulla” can be used in a large field. It can sense the weak electric field around it, determine the position of the target, and quickly attack. The superior sense of smell, the sensitive sixth sense, the super power of the shark makes its prey invisible.

Some animals use electricity to find prey, while others use electric current to attack.

Chemical power

Electric eel is probably the most well-known electric animal. Although it is called “Electricity”, it is not a kind of squid. In terms of biological classification, eDonkey is actually more similar to squid, but the name “Electric Donkey” is already a kind of fish in the Congo River.

The eDonkey is a master of electric play. Its discharge capacity comes from special muscle tissue. The head is the positive pole, the tail is the negative pole, and there are thousands of discharge bodies on the body. It can instantly release more than 600 volts of electricity. According to calculations, an electric raft can even pour a horse. The human body safety voltage is 36 volts. If you encounter a power cymbal, it is best to stay away from it. The eyes of the eDonkey are almost invisible. In general, it continuously releases a weak current to sense the surrounding environment. When you feel the prey, the eDonkey will instantly release up to 650 volts of electricity. The average small fish can’t withstand such high-intensity voltage, and it is quickly stunned. The eDonkey can easily swallow the prey into the abdomen.

The discharge capacity of the gallbladder fish is not weak. You probably saw a scene in the cartoon that rushed from the human eye, a scene that could not be realized in reality, but the darling fish can do it.

The gallbladder fish head is large and square, and the eyes are on the top of the head. The eye muscles of the scorpion fish are similar to those of the electric scorpion and can also be discharged. This kind of fish is good at lurking, and buried itself in the mud at the bottom of the water all year round, only showing the two eyes and a big mouth at the top of the head. If there is a prey passing over it, the starfish will spurt a strong current in the eyes, and the prey will be corona instantly, falling into the big mouth that has been waiting for a long time.

Is it true that only the creatures in the water use electricity, and there is no “player master” on land?

Of course, spiders are a classic example.

In the corner, the delicate spider web is open, and the sticky spider web can stick to the unlucky bugs. The spider stays on the net quietly, waiting for food to come to the door. It seems that spider webs can only “wait for the rabbit”, but scientists have found that spider webs can also take the initiative.

They found that the surface of the spider web actually has static electricity. When the bees or other insects flap their wings, they will produce a certain amount of positive charge. The static electricity on the spider web may interact with each other, and the flying insects will be sucked onto the net. Stick so that it can’t break free. If you want to experience the static electricity of the spider web, you can observe the weak undulations of the spider web by gently rubbing the spider’s net with a heated plastic ruler.
