Blue Glass snails are terrestrial, meaning they live their life predominantly or entirely on land. The majority of their food source then comes from plant vegetation. Some of their food income also comes from leaves, mushrooms, fruit, fungi, and several other kinds of plant material. In order to consume their food, Blue Glass snails use an organ called a radula. The radula is a rasping tongue found in most mollusks (Hickman, 2009). The radula contains rows of chitinous teeth, pointing backward that allow the snail to tear, pierce, or cut food particles and pass these food particles into the esophagus (Hickman, 2009). As the food leaves the esophagus, it passes into the stomach, through the intestine, and finally out of the body through the anus.

Specific information for the Blue Glass snail was not found for being a host or                                          serving others as a host, but other snails can act as both.

Blue glass snails have an open circulatory system which includes a heart,                                                 blood vessels, and blood sinuses. The blood moves through a serious of                                                  channels and open sinuses to supply oxygen to the tissues of the body (Hickman, 2009).
