Helix pomatia Linnaeus, 1758 Helix pomatia, common names the Roman snail, Burgundy snail, edible snail or escargot, is a species of large, edible, air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Helicidae.
The decollate snail, scientific name Rumina decollata, is a medium-sized predatory land snail, a species of terrestrial pulmonate gastropod mollusk in the family Subulinidae. It is a European species that has been introduced in a number of areas worldwide.
The garden snail has a flat “muscular foot” that helps it move with a gliding motion aided by the release of mucus to reduce the friction with the surface. This mucus is the reason of the trace that snails leave when they move around.
