Locomotion in Snail:
Locomotion is snail, like other molluscs, takes place by a specialized organ, the foot. Snail moves by the contractions of muscles underside the foot. These contractions are brought about under the influence of hydrostatic pressure of the body fluid. The waves of contraction from front to rear push the animal forward. This movement is made easy by a slimy secretion of the mucuous gland poured in front of the foot and animal virtually slips forward. This gives rise to the familiar shinning tract left by a moving snail.
