MOVEMENT IN SNAIL
• A snail is a very slow-moving animal.
• Snails have a shell, inside which they can hide to protect themselves from heat and enemies.
• The shell is the outer skeleton, but is not made of bones.
• They also have a pair of tentacles that bear eyes at the tips.
• Snails move using a muscular organ called the foot.
• The foot produces a slimy substance called mucous. It crawls on the layer of mucous.
• The mucous reduces the friction between the foot and the ground (or any other surface) by offering a smoother surface to crawl on.
• The muscular foot produces wave-like movements that push the snail's body forward.
• A trail of mucous is left behind when the snail crawls.
• Sticky mucous also enables the snail to crawl on a variety of surfaces.
