Terrestrial snails posses an anatomic structure that is used for feeding.  This structure is found only in the phylum Mollusca; primarily in the class Gastropoda.  The radula is located near the snail's foot on the anterior portion of the snail's body.  Radula is defined as a rasping tongue that scraps or cuts food from their environment before they are swallowed.  The radula consists of longitudinal rows of chitinous teeth.  The genus group, Helicodiscus, possess 77 rows of teeth in their radula. (Pilsbry, 1998).

Land snails feed primarily upon vegetation present in their habitat.  They also feed upon rotting leaves/wood, sap, and fungi (Hotopp, 2002).
