These snails eat dead plant and animal matter and various other detritus. Because Physella acuta forages mainly on epiphytic vegetation and on the macrophytes, whereas other gastropods (Planorbis planorbis, Radix ovata) exploit the algal cover or phytobentos on the bottom, competition between Physella acuta and other gastropods appears to be ...

The giant African snail is a macrophytophagous herbivore; it eats a wide range of living plant material, commercially important fruits and vegetables, ornamental plants such as flowers, native plants, as well as weeds and detritus plant material. At different life stages and temperatures, the snail has slightly different feeding preferences.
The radula works like a file, ripping food into small pieces. Many snails are herbivorous, eating plants or rasping algae from surfaces with their radulae, though a few land species and many marine species are omnivores or predatory carnivores. Snails cannot absorb colored pigments when eating paper or cardboard so their feces are also colored. [3]
