Planorbids tend to occur in bodies of water with a firm mud bottom and high levels of decaying organic matter. Most species seem to prefer lentic habitats (lakes, wetland or ponds). With the exception of Helisoma anceps which occurs more often in river pools, they prefer minimal current. Planorbid snail are scrapers of benthic surface and have been shown to eat bacterial films and algae.
