Recently, when the scientific research team of Guizhou Normal University and the scientific research personnel of the reserve conducted a comprehensive scientific research in Xishui National Nature Reserve, Guizhou, freshwater sponges were found for the first time in Changchigou of the reserve. There is no similar record in the historical list.
Sponges are a very ancient animal that originated more than 600 million years ago.

Freshwater sponges are the simplest multicellular animals in the world.
The structure of the freshwater sponges discovered this time is very simple, concentrated on the moss, no obvious tissue differentiation, no organs and systems.
Experts said that the discovery of freshwater sponges in Changchigou in the protected area this time shows that the water quality in this area is good and the ecological protection has achieved remarkable results.
The number of freshwater sponges discovered this time is relatively large, and the scientific research team is conducting follow-up related monitoring.
