Description

File:Planorbis planorbis drawing.jpg

This species, like all planorbids, has a sinistral shell. The width of the shell is 15 – 20 mm. The keel on the periphery of the shell is near the edge closest to the spire side, which is carried downwards in life.

Ecology

The habitat of this species is shallow standing and slowly running freshwaters on a mud substrate, also ponds and temporarily drying flood waters, up to 1 metre depth. Planorbis planorbis does not tolerate intensive water movements but is tolerant to eutrophic conditions.
