snails and slugs
Get to snails [same breed] put them in a tank with wet soil plenty of greens and in 1-2 week's they will mate and lay eggs
If you are asking if snails crawl or walk they do neither. They slide on mucus.
snails slide on there foot using a sticky mucus to travel it may take a long time depending on where they are going.
The scientific name for the trail left by a snail is "mucus trail." Snails produce mucus to aid in locomotion and protect themselves from rough surfaces.
One kind of snail mucus is produced by the foot and is used for crawling. The second kind of external mucus is used to coat the external parts of the body. This coating helps prevent desiccation of the exposed soft tissues.
For protection, to keep their skin hydrated, and for movement.
snails
In general, water snails predate upon plants. They do not help them they destroy them.They dont help and they dont harm
Snails leave a slime trail because of their limited movement. Snails are very small creatures, and coupled with the wait of their shell, they do not move very fast. Snails leave a trail of mucus, not slime (well i guess it counts as slime..:) in order to help them slip along faster. They use it to glide along on, and it helps them stick so they can hang upside down.
Mucus is the name of the snails slime.
