The world is big, there are no wonders, and around us, there are many "ancient" creatures.
This time it happened in Chongqing! Recently, a teacher in Mawang Town, Youyang County, Chongqing, when inspecting the school's fire pool, found a lot of small white creatures tumbling in the water, much like jellyfish in the ocean.
Later, experts found that these were peach blossom jellyfish known as "living fossils in the water", which is a rare freshwater jellyfish, which was born 550 million years ago and belongs to the world-class endangered species!
No wonder that as soon as the news was sent, many people said that this was the real treasure, much higher than the level of dinosaurs.
It's just that this discovery has caused many small partners to question:
1, it turns out that there are freshwater jellyfish;
2. In the end, it shows that the water quality of this pool is good, or is the water quality poor?
3, the fire pool is not large, so where do jellyfish come from?
4) Is this a challenge to evolution?
These problems are actually very well explained. Peach blossom jellyfish is a most primitive low-level invertebrate, although it is a living fossil, but this does not violate the theory of evolution, if some characteristics can be maintained in a more stable and adaptable situation, there will be no evolution.
Peach blossom jellyfish is the name of our country, in the world, itself is known as freshwater jellyfish, the distribution range is very wide, because it and peach blossoms, only appear once a year, so it is called peach blossom jellyfish, ancient times called "peach blossom fish".
They prefer a slightly acidic environment, so fresh water can naturally survive, and the entire life history of peach blossom jellyfish is the alternation from asexual reproduction to sexual reproduction. When I was a child, the environmental requirements were generally very low, but once it became the shape of a jellyfish, it was very demanding on the environment, and the water quality must be good.
Therefore, this shows that the water quality of this fire fighting pool must be very good.
Although the pool is not large, it is connected to the outside world, and with the continuous rain and rising water in Chongqing some time ago, the exchange of water bodies is very normal. They have been found many times before in the Jialing River and commonly.
The peach blossom jellyfish found this time are very rare, not because the number is too small, but because they appear only once, and they are very short, basically difficult to be found.
This kind of "old antique" that has lived long enough is now basically used for ornamentation, except for scientific research. After this time was discovered, some netizens actually said that they wanted to eat it and see what the taste was, after all, it came from the "ancient times".
I would like to say, only 15-25 mm of peach blossom jellyfish, how to eat? Maybe some netizens said: This is difficult? Cantonese people teach you!
