Adaptation Olive Vertigo moves by creeping on a flat "foot" underneath the body. The muscles of the foot contract and expand and to creates a rippling movement that slides the snail along. The "foot" has a special gland that produces a slimy mucus to make a special track. The slime is secreted from the front of the foot and hardens when exposed to air. (Tryon 1918)

Its soft body is protected by a hard shell. When its disturbed, it will withdraw or pull itself back inside its shell. A snail is most active at night and on cloudy days, as the sun can dry it out. During very cold weather or winter, it hibernates in the ground. (Löve 1963)
