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.

Taxonomy

This species was described under the name Paludina catayensis by French Jesuit Pierre Marie Heude in 1890.[1] Later reviewers treated the specific name catayensis as an orthographic error and changed the specific name to cathayensis.[2] There is high intraspecific variation of shells within the genus Cipangopaludina,[2] so Wilhelm Kobelt (1909)[3] considered this taxon as a subspecies of Vivipara chinensis. Later authors Yen (1943), Liu (1991) and Lu et al (2014)[2] considered this taxon as a separate species.

Distribution

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).[4]

Description

The width of the shell is 24.3–50.5 mm.[2] The height of the shell is 27.7–58.5 mm.[2] The shell has from five to six whorls.[2] The apex is pointed.[2]

C. cathayensis has gills and an operculum. The kidney is triple-shaped.[2] 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]

Ecology

It inhabits lakes, reservoirs and ponds, as well as grassy paddies, where it clings to aquatic plants.[4]

Each gravid female carries more than 60 embryos inside her.[2] The shell of embryo has three whorls.[2]

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]

Human use

Шаблон:Infobox nutritional value It is used as human food and in the preparation of medicines, and as feed for fish, poultry and livestock.[4] It is also used as a fertilizer.[4]
