Answer 1: When you pour salt on a snail (or slug) the water is very rapidly pulled out of the cells of the snail's body by a process called osmosis. As it dries out, the snail's body produces a slimy substance to protect itself. If enough salt is poured on the snail it will die of dehydration fairly quickly.
When there is no moisture outside, garden snails and slugs go into hiding to prevent water loss and avoid predators. Snails find cool spots such as empty plant pots, under window-sills, rocks, or in piles of firewood. To reduce water loss, they seal themselves in using dried mucus.
They stay under logs and stones or under ground cover. They also hide under planters and low decks. At night they come out to eat.
Snails are similar to amphibians in that they breathe through their skin (though they also have gills or lungs). Under dry conditions, they seek cover to combat dessication. But when it rains, they "come out," just like many amphibians.
You will find that snails are most active at night. They may come out during the early morning hours as well.
Freshwater snails carry a parasitic disease called schistosomiasis, which infects nearly 250 million people, mostly in Asia, Africa and South America. “It's one of the world's most deadly parasites,” says Susanne Sokolow, a disease ecologist at Stanford University's Hopkins Marine Station.
A snail can go forage randomly and still return to a specific resting place. Snails find mates through air- or water-borne chemicals and any snail that wants to reproduce has to be able to navigate towards them (slug example). So yes, a snail always really knows where it's going.
Behavior, Diet & Habits
Slugs and snails hide in damp places during the day. They stay under logs and stones or under ground cover. They also hide under planters and low decks. At night they come out to eat.Snails eat a wide range of vegetables and ornamental plants, especially seedlings and other soft growth. They are good climbers and can be found high up in some plants. Most damage is done in spring by snails feeding on seedlings, new shoots and plant crowns.
Scientists turn snails into slug-like creatures. Summary: Biologists have re-shaped the body design of snails. Exposure to platinum results in the formation of an internal shell instead of the normal external shell.

Snails and slugs rank among our most despised garden pests.
These slimy mollusks emerge from hiding at night and chew holes in leaves and flowers of many succulent garden plants and fruit. Slugs and snails are similar in structure and biology, except slugs lack the snails' external spiral shell.Vertebrate predators of snails and slugs include shrews, mice, squirrels, and other small mammals; salamanders, toads and turtles, including the uncommon Blandings Turtle Emydoidea blandingii; and birds, especially ground-foragers such as thrushes, grouse, blackbirds, and wild turkey.

Land snails obtain calcium from their environment in a variety of ways, depending upon their autecology. They can be found rasping old or occupied snails' shells, bones and antlers, rock particles or larger stones and outcrops, and the soil that they regularly consume contains calcium.
Beetles: Carob beetles are very effective slug predators – the larvae and beetles eat the eggs and the tiny slugs.

Slugs are nocturnal and feed at night when we can't see them. They prefer cool, dark, moist hiding places during the day. Cool, wet spring conditions are ideal for slugs, resulting in early, serious damage to plants.
Seaweed. Seaweed, both fresh and powdered is a good home remedy for slugs, and it's great for soil as well! Seaweed is a great natural repellent for slugs, and will help keep your garden free from slug damage.
How Did I Get Snails and Slugs? Moist plant debris, underneath rocks, low weeds, mulch and fallen logs all provide hiding places for snails and slugs. Moisture is a key requirement for snails and slugs since they are adversely affected by dry conditions and the loss of body moisture.
Personal shopper. A slug is mostly made of water and because of this it needs a moist environment or it will turn into dessicated slug (a delicacy that has so far not made it on to any molecular cuisine menus). So while you have a problem with slugs, it's because you have a problem with damp.
Slugs stay active when temperatures remain above 5C (41F). Because of the warm winter, slugs have not gone into hibernation and have been eating and and breeding through the winter months.
Slugs overwinter as adults or eggs, concealed beneath the soil surface, under garden debris or light mulches. Applying a leaf mulch once the ground has frozen most likely is not going to increase your slug population. By that time, they have stowed away in the soil.
While they don't pose any physical danger to people, snails and slugs are a nuisance when they come indoors. Outdoors they can cause considerable damage to plants in gardens and flowerbeds. These pests eat large holes in leaves and may devour entire seedlings.
A snail uses its single long, muscular foot to crawl on a layer of mucus-like slime that it secretes. The mucus does help the snail stick to surfaces, however, and comes in handy when traveling up a wall or across a ceiling, upside down.
Slugs and snails are very important. They provide food for all sorts of mammals, birds, slow worms, earthworms, insects and they are part of the natural balance. Upset that balance by removing them and we can do a lot of harm. Thrushes in particular thrive on them!
Slugs are hermaphrodites, having both female and male reproductive organs. Once a slug has located a mate, they encircle each other and sperm is exchanged through their protruded genitalia.
Although slugs and snails can give off foul-tasting substances that prevent them from being ingested, some dogs just appear to ignore these warnings. The worm needs slug and snail hosts in order to grow and develop, and it's from eating these that infection may occur, then by the dog passing larvae in its waste.
Slugs are hermaphrodites, having both female and male reproductive organs. A few days later, the slugs lay approximately thirty eggs in a hole in the ground, or beneath the cover of an object such as a fallen log.
Like other mollusks, land snails have a mantle, and they have one or two pairs of tentacles on their head. Their internal anatomy includes a radula and a primitive brain. Tiny snails hatch out of the egg with a small shell in place, and the shell grows spirally as the soft parts gradually increase in size.
