Valvata cristata is a species of minute freshwater snail with an operculum, an aquatic gastropod mollusk or micromollusk in the family Valvatidae, the valve snails.

Distribution

Shell description

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.

Ecology

This species lives in stagnant and slow-moving water. Myzyk (2002) described life cycle of Valvata cristata.
