The Lambda Snaggletooth eats a variety of different foods. They eat mainly vegetable matter, consisting of nettles, thistles, and decaying leaves. They also eat fungi and algae, although they prefer decaying plant matter (Baker, 1939).
Once the snail finds it's food, it uses a lingual ribbon (radula) to chew it (Baker, 1939). The food enters the snail's esophagus, and then moves to the stomach. Once the food is in the stomach, it is broken down and used by the snail. In most gastropods, the apical digestive gland, or "liver" is where the snail will store food for periods of inactivity (Miller,1978). The food that is not stored is carried by the snails open circulatory system to various parts of the snails body.
