A: A snail scrapes its food, rather than chews it like we humans do. A flexible structure called the radula in the snailâs mouth is lined with neatly organized rows and columns of tiny tooth-like projections. The snail moves its radula over the food, scrapes off bits of it, and swallows.
Snails eat by asserting radula against the leaf rasping it and scraping away particles. This can be observed particularly when feeding a snail. Snails are herbivorous which is why most of their diet comprises plants and vegetation.In the wild, snails are very fond of eating leaves, fruits, mushrooms and other types of vegetation. These animals predominantly feed on living plants; however, they can ingest decaying plants as well.These species also feed on flowers, algae and plant bark.nails eat by asserting radula against the leaf rasping it and scraping away particles.
