Recently, the news that peach blossom jellyfish was discovered in Sumu Park, Meishan City District attracted the attention of many citizens. "The weather is cooler today, so hurry up and take a look at this peach blossom jellyfish called the 'Giant Panda in the Water'. I saw it, it's a bit too many!" Mr. Li, who lives next to Sumu Park, came to "see the strange" early in the morning. The peach blossom jellyfish in Sumu Park can be seen by the water at the naked eye, and there are a lot of them.
According to Zou Zhihui, the director of Sumu Park, on the morning of July 20, the park security guard accidentally discovered a creature similar to a jellyfish while patrolling. After verifying and verifying with the Municipal Ecological Environment Bureau, Housing and Urban-Rural Development Bureau and other departments, it was confirmed that it was a peach blossom jellyfish, a jellyfish that lives in fresh water.
What is a peach blossom jellyfish?
The editor will first introduce the science:
Peach Blossom Jellyfish is older than dinosaurs. Its survival dates back hundreds of millions of years ago. It is the most primitive and lowest invertebrate coelenteric animal on the earth. It is known as the "living fossil" of biological evolution research and is known as the "giant panda in the water". At the same time, due to the sensitivity of this organism to the environment and the damage to its living environment, it is listed as a "critically endangered" species.
Peach blossom jellyfish generally live in still water, such as lakes or ponds, and is also the only jellyfish that lives in fresh water. It has high water quality requirements. The waters suitable for its survival must be non-toxic, harmless, clean, and mostly acidic.
Where does the peach blossom jellyfish come from? The staff is not sure yet. Zou Zhihui, the director of Sumu Park, introduced that when the Municipal Landscape and Greening Service Center began to take over the management of the park in 2019, the surface of the water body was densely covered with water and grass, which seriously affected the appearance and the water body was black in color, and the overall water quality was not good. After a long period of normalized and refined management, multiple groups of staff are arranged to salvage aquatic plants and floating objects every day. At present, the aquatic plants have decreased significantly, there are almost no debris on the water surface, and the water body is clearer.
Sumu Park is just a microcosm of the water management of rivers and lakes in Meishan. In recent years, Meishan has fully implemented the new development concept, insisted on putting the river (lake) chief system in the first place, and continued to increase efforts to control water, implemented the four actions of "clearing rivers, protecting banks, purifying water and water conservation", and focused on strengthening river and lake management, and promoted the continuous improvement of water quality in the basin.
The water is clearer and the water quality is better! In recent years, the achievements in Meishan water environment governance have been shown. In the first half of this year, the average water quality of 17 municipal rivers (lakes and canal systems) reached 100%, including 5 Class II water quality rivers and 12 Class III water bodies. In particular, the outbound water quality of Minjiang and Qingyi Rivers was stable and better than the inbound water quality, setting a record high since the implementation of the river and lake chief system.
