Triodopsis tridentata eat organic and inorganic materials (Barker, 2001).  The main food source for snails are plants which makes them herbivores (Barker, 2001). Outside of eating plants, snails will eat fungi and other animal matter along their path (Speiser, 2001). Many snails search for food at night because locomotion requires mucus which stays more moist at night than during the day (Atkinson, 2003). Terrestrial snails, like Triodopsis tridentata, use their chemical sense organ to find food (Atkinson, 2003). Once the snail finds food it uses its radula to scrape and grind the food (Atkinson, 2003). The radula, better explained under the Adaptation page, is a rasping tongue like organ found in most molluscs (Hickman, 2009).  Most snails house a single nephridium which serves as an excretory organ, much like the human kidney, to digest their food (Hickman, 2009).
