Some bivalves are epifaunal: that is, they attach themselves to surfaces in the water, by means of a byssus or organic cementation. Others are infaunal: they bury themselves in sand or other sediments. These forms typically have a strong digging foot. Some bivalves can swim.
Chitons creep along slowly on their muscular feet and cling to rocks.
Most snails move by gliding along on their muscular foot, which is lubricated with mucus. This motion is powered by succeeding waves of muscular contraction which move down the undersurface of the foot. They produce mucus in order to aid locomotion by reducing friction, and the mucus also helps reduces the snail's risk of mechanical injury from sharp objects.
