They have a mantle, and also have a shell for their protection. Their body is not segmented, and they are bilaterally symmetrical, and are coelomates. Snails come under the class gastropod. All of these morphological and anatomical traits put snails under the classification of a mollusc.

snails, clams, squids and octopodes Mollusks are a large group of invertebrate animals. Mollusks have soft bodies, and their bodies are not divided into rings like the segmented worms called annelids . Mollusks don’t have legs, though some have flexible tentacles for sensing their environment or grabbing things.

Lifespan. Most species of land snail are annual, others are known to live 2 or 3 years, but some of the larger species may live over 10 years in the wild. For instance, 10-year old individuals of the Roman snail Helix pomatia are probably not uncommon in natural populations.

They like to have their shells rubbed. They also like to be rubbed around the head and neck. That is also the snail version of foreplay. Snails will eat while in your hand or cozy up there for a nap.

Freshwater snails: 20,000+ deaths a year The freshwater snail carries parasitic worms that infect people with a disease called schistosomiasis that can cause intense abdominal pain and blood in the stool or urine, depending on the area that’s affected.

Formerly icecool2. EmdeReef said: Unless you have whelks, nassarius snails generally won’t kill a healthy snail. They’ll go after dead or dying snails, clams, even fish.

Snail-borne parasitic diseases, such as angiostrongyliasis, clonorchiasis, fascioliasis, fasciolopsiasis, opisthorchiasis, paragonimiasis and schistosomiasis, pose risks to human health and cause major socioeconomic problems in many tropical and sub-tropical countries.

Here are a few tactics we recommend:

1. Use Bait. If you have a can of beer in your refrigerator, you’ve already got an effective form of snail bait.
2. Use Traps.
3. Use Barriers and Repellents.
4. Introduce Predators.
5. Plant Snail-Resistant Plants.
6. Kill Snails With Salt, Chemicals, or Pesticides.
7. Adjust Your Watering Schedule.

Crushed eggshells, sand or diatomaceous earth sprinkled around plants that the garden snails seem to prefer will deter and eventually kill these pests. Set out traps – A common snail trap is the beer pan. Simply fill a shallow pan with beer and leave it out overnight.

Caffeine kills slugs and snails. Coffee grounds are already recommended as a home remedy for keeping slugs and snails at bay. Grounds repel slugs, Hollingsworth found, but a caffeine solution is much more effective, he says: “Slugs turn back immediately after contacting the [caffeinated soil].”

Eliminate the Snails and Slugs The vinegar will dissolve the snails, and you can spray the remains off your patio with a garden hose. Vinegar acts as an herbicide in some cases, though, so try to spray the snails after they’ve left the plants or you’ve picked them off.

Moist plant debris, underneath rocks, low weeds, mulch and fallen logs all provide hiding places for snails and slugs. Moist locations are especially attractive if a food source is nearby. Both a snail and a slug will eat plant leaves, flowers, and fruits, particularly those at ground level.

Slugs will come inside for something they need, likely warmth or shade. So, knowing what attracts them could help keep them at bay. “The Yellow Cellar slug mostly eats mould and algae but can also be found eating leftovers, pet food and compost. “It is attracted to dark damp refuges such as vents and drains.

It really could be the same one as slugs leave their own individual scent trail so they can find their way home. The rest is apparently underground doing things that slugs do like eating seedlings, laying eggs, and feeding on roots and seed sprouts.

In my opinion, it is not necessary to kill slugs and snails using any of the methods described above. There are much wiser ways to deal with the pests. You do not need to fight them directly. It is enough to ward them off passively; for example, with barriers against slugs and snails.

Poison baits are effective, but they do not kill instantly, so there may be a measure of suffering before death. Crushing them under foot is definitely quick and probably the most humane method, in that there isn’t a lingering death.

Slugs don’t scream or cry out, but they do have pain receptors like most other creatures.
