How do snails produce mucus?

Snail slime is secreted by glands located all over the body, though the largest, and that responsible for the silvery trails, is at the front of the foot. When resting, snails produce enough mucus to glue themselves to a substrate and create a membranous seal called an epiphragm covering the opening of the shell.

What kind of slime does a slug have?

Snail and slug slime is mucus secreted from the bottom of a slug or a snail that enables the creature to efficiently move. A slug or a snail leaves a a trail of his slime wherever he goes. The mucus isn’t required for all movement, though.

Why do we need slime trails for slugs?

Slime trails are a tactical compromise. The slug loses water in its mucus, which restricts its activity to the cool damp of night or to rainy days, but the lubrication that slime offers saves energy that would otherwise be needed to overcome friction.

Why do slugs secrete mucus slime at night?

Slugs deal with this dilemma by secreting copious amounts of slime from skin glands, which keeps the skin moist and acts as a barrier against desiccation. Even so, the animals are usually seen in damp environments rather than dry ones and are most active at night.

Why do slugs and snails produce a Silver Trail?

Slime makes for an excellent lubricant, and bizarrely also glue! The characteristic slime trail left by slugs and snails has some of the qualities of both a glue and a lubricant. It helps the creature glide forwards when pressure is lifted, or stick to surfaces when pressure is applied.
