There are very few snails of the species, Discus patulus, but the few that are found and studied
are known to be endemic to the United States.  The snails are specifically found in Maryland, South Carolina, Ohio,
Wisconsin, Tennessee, Kentucky, and around Lake Erie.  View map location at the Encyclopedia of life.

The Domed Disc snail is not particularly picky with its habitat. This species can be located in moist
areas among leaf litter or under logs in deciduous forests, river valleys, and ravines.  They enjoy shaded
areas.  For the optimal habitat, Discus patulus enjoys burrowing in soft, loosened bark of rotting logs
which provides the perfect habitat needs(Pilsbry 1948).  

This species of snail blends in with its rocky habitat very well because of their brownish shell coloration.
