The endangered peach jellyfish was found at Guilin Sewage Treatment Station, which has both academic and ornamental values.

Recently, a rare creature appeared in the sewage treatment station of The Lushan Campus of Guilin University of Technology.
identified as peach jellyfish, first born 550 million years ago, appeared earlier than dinosaurs.
Peach Blossom Jellyfish has both academic value and ornamental value Guilin University of Technology School of Environmental Science and Engineering Professor, doctoral tutor Zhang Wenjie introduced, peach blossom jellyfish was found in the school's Lushan campus sewage treatment station lake water treatment system of the deep treatment pool.
the treatment system uses ceramic microfiltration technology to improve water quality in the lake water in the campus.
September, the species was identified as peach jellyfish after being genetically sequenced by a Shanghai company after three years in a row at the same location.
this jellyfish is white, pink or slightly blue-green transparent umbrella-like, diameter of about 15-25 mm, tentacles about 20 mm long, umbrella-like around the threaded string tentacles around its round edge (ring edge), is the only kind of fresh water life of small jellyfish, by the way to produce jellyfish.
peach jellyfish are abundant in fresh water such as ponds, lakes and rivers, the water environment is very high, suitable for its survival of the water must be clean, non-toxic harmless, and weak acidic.
peach jellyfish are carnivorous animals, food groups mainly 0.2-2.0 nanometer plankton-based, including protozoa, flatworms, nematodes, link animals, foot and fish fry.
peach jellyfish is one of the most endangered rare aquatic species, so it is called "the giant panda in the water".
as a veritable "living fossil", peach jellyfish has a high research value and ornamental value.
Zhang Wenjie said that, as a key species in the course of biological evolution, peach jellyfish in their own unique way to record the development of life on earth, has important academic value. at the same time,
, because of its beautiful shape and rare number, peach jellyfish has a high ornamental value.
" earliest historical information about peach jellyfish comes from classical Chinese literature, suggesting that the species is likely to have originated in China as early as China.
" Zhang Wenjie pointed out that once this precious species becomes extinct, it is not only a loss of species diversity in China, but also a permanent loss of cultural resources recorded in ancient China as "peach fish".
's call for the protection of peach jellyfish has attracted the attention of the domestic academic community and others, experts have begun to study specific measures to save peach jellyfish efforts to save this extremely dangerous species.
live in warm waters, many in the summer and autumn festival in the world for more than 100 years only found 11 species of peach jellyfish. although the
is widely distributed and widely distributed in China, but because the water quality of peach jellyfish is polluted, the natural environment is destroyed, the ecology is out of balance, the whole country can be picked up peach jellyfish is no more than two or three places.
distributed in China's 9 species of peach jellyfish, Yichang peach jellyfish, Xinyang peach jellyfish and short-hand peach jellyfish have been included in the national endangered animal red list of the highest level - extremely endangered species, Hangzhou peach jellyfish, Leshan peach jellyfish, Sichuan peach jellyfish, Chinese peach jellyfish and Chuxiong peach jellyfish and other 5 species are listed as endangered species.
peach jellyfish are often found in warm waters, with the most summer and autumn festivals in June-October each year.
this is because the proper water is mild and abundant food to make it abundant, their numbers tend to peak in July-September, and by the end of October or early November, the number of peach jellyfish populations has declined rapidly and since then disappeared.
peach jellyfish has a positive reaction to sunlight, bright light, there is a certain light-sensitive, early and late distribution in the upper or surface of the water, strong light at noon, high water temperature is more distributed in the water's lower and middle layer.
is easier to find on clear, windless mornings and in the evening. Zhang Wenjie,
, said that the survival conditions of peach jellyfish are more stringent, so in the premise of meeting the water temperature and pH and other hard conditions, but also to reduce the natural water ecosystem in which they live interference and destruction.
domestic sewage and industrial wastewater produced by human production and living, must be treated to meet the standards before discharge into natural water bodies, to ensure the quality of natural water bodies. in addition,
, human semen may transform the structure of natural water bodies in the course of development, such as surrounding lakes, building dams and river diversions, etc. will affect the ecological environment of peach jellyfish.
since the discovery of peach jellyfish, Zhang Wenjie's team has been collecting data on water quality, paying close attention to water quality changes, and trying to use big data to explain the relationship between peach jellyfish and water quality.
Zhang Wenjie said that the water quality of peach jellyfish's survival water is currently being monitored, and the study of its genetic composition and species is also being carried out simultaneously.
"How did human scarfish coexist peacefully during the long-term historical succession process? Until modern times, peach jellyfish from the disappearance to the re-emergence, how to interpret their own genetic code? The genetic characteristics of peach jellyfish and their relationship with ecological environment and human health are the main research directions of our research group.
," Zhang Wenjie said.
