Detail
Distribution. Czech Republic - Bohemia and Moravia, Slovakia, Poland, Germany - (Arten der Vorwarnliste), Netherlands, the British Isles: Great Britain and Ireland, Hungary, Kaliningrad Oblast, Russia and other areas. The shell of this exceeding small (2-4 mm) Valvata species is very flat in its coiling, and therefore it somewhat resembles a Planorbis shell. However, the shell is dextral in coiling and has an operculum. The shell is transparent, has 3-3.5 whorls in a circular aperture. The umbilicus is wide and open, more than 1/3 of shell diameter. This species lives in stagnant and slow-moving water. S. Myzyk (2002) described life cycle of Valvata cristata.
