Planorbarius is a genus of air-breathing freshwater snails, aquatic pulmonate gastropod mollusks in the family Planorbidae (the ramshorn snails), which all have sinistral or left-coiling shells.
Description All species within family Planorbidae have sinistral shells.
Many species in this genus have been found to be diploid with 18 pairs, or 36 total, chromosomes. Differences in chromosomal length and other indicators were not different enough to distinguish individual species.
