Planorbis planorbis is a species of air-breathing freshwater snail, an aquatic gastropod mollusk in the family Planorbidae, the ram's horn snails.[3]

Distribution[]

Description[]

Drawing of the shell of Planorbis planorbis.
Upper image: Lateral view showing the profile of the shell.
Lower image: Umbilical view; this side is carried uppermost in the living snail.

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.
