The Eastern flat-whorl consumes a variety of different organic material. Some of this material includes; plants, fungi, animal tissue, and soil. The majority of their diet is composed of aging leaves of deciduous trees, flowers, fruits, and shoots (new growth of flowering plants) (Badra,2008). It is believed that Planogrya asteriscus prefer this type of material because it contains low amounts of toxins in it. Algae and mosses can also be consumed, but grass is almost never. Numerous types of fungi are also consumed even though some of them are very toxic to mammals. Humic acid, which is found in the soil of their moist habitat, is an extremely important nutrient in their diet (Badra,2008). Snails are able to consume food with their radula. They use their radula to grasp food, then force it to the back of their esophagus. Their jaw contains teeth that are constantly getting replaced with new ones as the old ones wear out (Martin, 2000).
