Question

A snail can easily glide through rough surfaces. Explain the two bodily features that
allow it to do so.

Answer 1

Answer:

Land snails move by gliding along on their muscular foot, which is lubricated with mucus and covered with epithelial cilia.

Explanation:

This motion is powered by succeeding waves of muscular contractions that move down the ventral of the foot. This muscular action is clearly visible when a snail is crawling on the glass of a window or aquarium.

Snails secrete mucus externally to keep their soft bodies from drying out. They also secrete mucus from the foot to aid in locomotion by reducing friction, and to help reduce the risk of mechanical injury from sharp objects, meaning they can crawl over a sharp edge like a straight razor and not be injured
