The Olive Vertigo feeds on micro flora such as bacteria and
fungi found growing on living and dead plants. (Schultes 2011)
Food is obtained by scraping it up using its radula, a minutely
toothed, chitinous ribbon, which is typically used for scraping
or cutting food before the food enters the mouth. (Butterfield
2008) Once food has entered the mouth, digestion begins with
saliva that starts to break down food. The food is then
processed through the crop and into the stomach, where the bulk
of digestion takes place. The food is then passed through the
intestine and excreted via the anus, which is located above the
snail's "head." The picture provided is not of the Olive
Vertigo, but is a general snail layout for reference.
