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.
The diet and feeding behavior of land snails greatly depend on how hungry they are. Roman snails or edible snails are exclusively plant eaters, though they prefer limp foods to fresh green ones. They crawl very slowly and often eat their food in an unhurried manner when they are in direct contact with it.
