Drawing of shell and operculum of Bithynia leachii

Shell description[edit]

The width of the shell is 3-7 mm. The height of the shell is 4-8 mm. The colour is brown or grey. There are 4 to 4.5 very convex whorls with a very deep suture in comparison to Bithynia tentaculata. The aperture and operculum upside are rounded.[9]


This species requires clean, calcium-rich water, which is slow-running and thickly weeded.[10]


This species can act as first intermediate host for Prosthogonimus ovatus (family Prosthogonimidae).[11]
