Witnessing the Rise and Fall of Eras Through the History of Rayfish
History is a process of continuous decomposition and fusion. After each extinction of a species, the natural ecosystem is rebuilt, and new laws take effect, and all things grow. Waiting for the next extinction of a species.

Since then, we have started to fear the apocalypse coming too quickly, destroying everything we have now. Reviewing history, the Earth has experienced five major extinctions. Some species remain forever in the midst of disastrous events, buried in dust. Species that miraculously survived took on the responsibility of reproduction, living even harder. And fish, as survivors who have experienced vicissitudes, witnessed the extinction of species, and are still widely active on Earth.

People find that there were fish-like traces in rock layers dating back to about 50 million years ago, which was the time of the Cambrian explosion of life, and the fish’s ancestors rode this train, becoming one of the earliest species recorded by humans.
The earliest fish did not have scales and their fins were not clearly defined. Although they had some features of fish, they were very different from the fish we see today. Eventually, the global temperature dropped, and the first major extinction event came, destroying 85% of the species, and fish were one of the survivors.

Electric eels appeared during the Jurassic period about 1.8 million years ago. This was the era when dinosaurs were dominant, and the growth of all things was rampant, with reptiles taking the lead. Many films try to recreate this bloody and chaotic era. However, history has not left us many clues in the process of evolution. Electric eels, which could not survive in the limited space, did not leave many traces. They struggled to survive in the midst of the mournful cries.
The evolution of a species often carries the characteristics of a certain period. Biota are part of history, and understanding biota can also help us think about the meaning of life. However, with the current pace of life, few people are willing to sit down and look at the life on this planet, when they experienced what kind of hardships, and at what moments, they burst into brilliant light of life.

Therefore, the electric eel is now a display item in aquariums; it is a food item in fish markets, where prices are negotiated; and it is a graceful pet in quiet fish tanks. We have gone from eating raw meat to enjoying life, and we have learned to better feel the meaning of being alive in life. Fish keepers like to think, so they don't feel bored even if they sit in front of the fish tank for half a day. Their understanding of life may be deeper than ordinary people, which is why more and more people like to keep fish and can cultivate a calm state of mind through keeping fish.

The appearance of electric eels is different from most fish, it is not a streamlined or torpedo-shaped fish, but like a phone screen membrane, thin and attached to the bottom or wall of the tank. Unlike most ornamental fish, it doesn’t constantly cruise in the fish tank, but like a phone screen membrane attached to a phone screen, tightly attached to the bottom or wall of the tank. At this time, if you have the opportunity to see its abdomen, you will find that it seems to be smiling at you, which is the result of generations of evolution, its nose and mouth are squeezed together.
Many people are confused by this face, thinking it is greeting them kindly. Although electric eels are docile, they are not easy to approach. Its caudal spine hides a poisonous thorn, and when it feels a sense of danger, the thorn will attack the opponent. If it pierces the body, the poison will spread quickly, and people who are poisoned will have dizziness, vomiting, and eventually fall into a coma.

In general, electric eels have a certain fan base in the ornamental fish market. Because this fish has a unique shape and a variety of colors, it is not easy to raise, and can reproduce in the fish tank. If you happen to have a large tank at home, you might consider keeping electric eels. However, their price is relatively high, ranging from a few hundred to a few thousand yuan.
