Question

5. Why is mucus secreted by a snail's foot?
​

Answer 1

Explanation:

Snails produce slime, which is a kind of mucus, via a special gland on the front of the snail's foot. Scientists initially thought that the purpose of the slime was to enable snails to move. ... Although their slime definitely helps them to move along more efficiently, snails don't need it to move.

Answer 2

Snail move with the help of their muscular foot made of strong muscles. They secrete a slimy mucus which makes the surface smooth and slippery which helps in easy movement of the snail. This movement is called 'Gliding Movement'
