Common name. Whirlpool ramshorn snail.

Morphology. Small-sized snail (up to 9 mm diameter). Shell is flattened and slim, strongly keeled. For more details see Welter-Schultes (2012: 59, figure at the bottom of the page).

Distribution and ecology. European-Siberian species up to 1000 m.a.s.l. Lives in small stagnant and slowflowing waters rich with vegetation in lowland regions. It can inhabit temporary habitats as well, yet it needs moist substrate preserved during drought periods ( Welter-Schultes 2012). In Serbia, scarce findings—the Danube River, a few ponds near the Danube, DTD canals, and Plazović and Jezava Rivers.

Other remarks. Vulnerable in Austria and Switzerland ( Welter-Schultes 2012). On the IUCN Red List it has been assessed as LC ( Moorkens et al. 2011).
