There are thousands of worlds, there are no wonders. If human beings really think that they are omnipotent, they are really ignorant. If you look at the entire biological world, you will find that some animals are really "gifted", and the ancients compared people to ants. For example, the weevil fish, which you may not be familiar with, has abilities that most people do not have. This animal lives in the vast expanse of Africa, its homeland, "under the iceberg" that you can't see, but occasionally jumps out to see the outside world.
Why is it called an elephant trunk fish? As the name suggests, is its nose very similar to an elephant's nose? In fact, it is only half right, and the real reason is that the lower lip of the elephant trunk fish is very long, which is similar to the elephant trunk, so it is given such a common name. If you know its family name, the pipe-billed fish family, I am afraid that the above "as the name suggests" does not exist. But people are accustomed to using empirical thinking to name it, analogous to some familiar thing to deepen the impression of strange things, so is it faster to remember? At the same time, because of the peculiarity of the "nose", the weevil fish are also classified as ornamental fish, which has aroused the curiosity of many people.
Elephant trunk fish mainly live in the Congo River Basin in western Africa, but there are also dinosaur fish, tilapia, crown fish and even nine fish and other strange-tempered and powerful species. Therefore, the elephant trunk fish is also a space for struggling to survive in the cracks, and it seems that it is also a bit bitter. There is a popular proverb that the strong are angry and draw their knives to the stronger, so the elephant trunk fish can compete with the stronger kind of people who are stronger than it to compete for living space, which shows that it must have superior strength.
The weevil is only 25-30 cm long at most, and its small size makes it more responsive and flexible. Its small size also adds a cute atmosphere to it, but at the same time it does not have the ability to fight against mighty animals, so it can only find some tricks to protect itself.
One gift of the weevil is discharge. When it comes to discharging animals, you may think of electric eels. Electric eels can be described as the king of discharge in freshwater fish, which can quickly release 860w of current in 2 milliseconds, which is enough to make an adult faint in an instant! Although the weevil is not as powerful as the eel, it is a talisman for the weevilfish.
The weevil's electrical organs, near the tail, emit electrical impulses 120 to 300 times per second, and these electrical signals are received by nerve cells in the head, which can help the weevil find food, find enemies and detect obstacles even in turbid water. However, when the tail of the elephant trunk fish moves, it will affect the release and transmission of electrical signals, which weakens its discharge ability to a certain extent, so it generally waits until the enemy rests before going out to move, this time is generally at night, so it is also stayed up as a nocturnal creature. But it is through darkness and this talent that the weevil fish will not be expelled by the biological world of survival of the fittest.
Weevils are rare animals in Africa and even less common in the country. But because it has the following advantages, in recent years, it has also become popular in China: first of all, it has a cute appearance and unique ability, and the ornamentality is very strong; secondly, the price is not very expensive; and finally, it is good to raise, as long as the temperature is controlled at 22-28 ° C, the water quality is controlled in neutral acid, and the rest is to lay the bottom sand and set the landscaping.
