Commonly known as a garden pest because of its insatiable hunger for veggies, this land snail has caused farmers distress across the world. Its shell is used for defense against predators, and they can tuck themselves inside and shut a door-like structure called an operculum to prevent predators from getting at them. Their shell grows with their body too, creating more spirals as the snail ages. It can sometimes be found on restaurant menus as escargot!
