Cipangopaludina cathayensis is a species of large, freshwater snail with an operculum and a gill, an aquatic gastropod mollusk in the family Viviparidae, the river snails.
This species was described under the name Paludina catayensis by French Jesuit Pierre Marie Heude in 1890. [2] Later reviewers treated the specific name catayensis as an orthographic error and changed the specific name to cathayensis. [3] There is high intraspecific variation of shells within the genus Cipangopaludina, [3] so Wilhelm Kobelt (1909) [4] considered this taxon as a subspecies of Vivipara chinensis . Later authors Yen (1943), Liu (1991) and Lu et al (2014) [3] considered this taxon as a separate species.
The species has a wide distribution throughout central and southeastern China, occurring in East China (provinces Shandong, Anhui, Jiangsu, Zhejiang, Jiangxi), Northeast China (Jilin), North China (Shanxi, Hebei) and Central China (Henan, Hubei, Hunan). [1]
The width of the shell is 24.3–50.5 mm. [3] The height of the shell is 27.7–58.5 mm. [3] The shell has from five to six whorls. [3] The apex is pointed. [3]
C. cathayensis has gills and an operculum. The kidney is triple-shaped. [3] The diploid chromosome number of C. cathayensis is 2n=18. [5] The complete mitochondrial genome of Cipangopaludina cathayensis is known since 2014. [6] Its length is 17,157 bp. [6]
It inhabits lakes, reservoirs and ponds, as well as grassy paddies, where it clings to aquatic plants. [1]
Each gravid female carries more than 60 embryos inside her. [3] The shell of embryo has three whorls. [3]
The pollutant removal in constructed wetlands with these snails was better, than in constructed wetlands without them. [7]
Parasites of Cipangopaludina cathayensis include trematode Aspidogaster conchicola . [8]
