Q
Why do snails leave trails?
A
Expert Answer
Snail slime (mucus) serves multiple functions: lubrication for movement (reducing friction by 90%), adhesion (allowing them to climb vertical surfaces), defense against predators (some slime is unpalatable), and moisture retention. The trail also helps following snails find food sources.
