Do snails outgrow their shells as they grow?

do snails outgrow their shell

Q: Can snails outgrow or leave their shell? A: No. They can’t, the shell is always present from the onset of their development. It is always attached to the snail, grows with the snail in a spiral shape.

If you’ve seen a snail without a shell, you’re looking at the snail’s cousin, the slug, which usually doesn’t have a shell.  The empty shells you have lying around are those of snails that are dead.

Snails don’t outgrow their shell! They don’t even move into new ones. If fall out of the shell, they are bound to die soon. Calcium intake also helps strengthen the snail’s shell. The land snails, sea snails and freshwater snails include about 43,000 known species.

Why do snails come out of their shell?

  • Environmental conditions

A snail’s environment determines whether or not it will emerge from its shell. You are most likely to find a snail at night, on cloudy days, or after it rains. Under those circumstances, the snail can break out of its shell and produce a slimy mucus that helps it move safely from one area to another.

  • Search for food

Snails come out of their shells in search of food. The snail’s tentacles contain olfactory neurons that provide it with a good sense of smell and taste, allowing it to find food. Snails also use their olfactory neurons to find slime marks left by other snails, which can lead to feeding areas or protective resting environments.

  • Mating ritual

Snails intercouse can last for several hours, most snails are bisexual, meaning they have both male and female reproductive organs. Before the snails mate, they cover each other in mucus.

After doing this, the two snails fertilize each other, allowing both to reproduce. Some hermaphrodite snail species can fertilize themselves even without a partner.

  • Laying eggs

Depending on the species, one snail can lay several hundred eggs. These eggs are small and should be stored in a warm, moist environment that is free from danger. Once the snail lays its eggs in moist soil, it can take several weeks for the newborns to hatch.

  • Vulnerability to predators

When attacked, the snail’s best defence is to retreat into its shell. However, some predators are able to break the snail’s shell, leaving it defenceless. The best chance for a snail to survive is to settle in protected areas by reducing the amount of time it spends outside its shell.

Then, do snails die when their shell is broken?

Like the nails of our own fingers, the shell of a snail is part of its body. If this shell is broken enough the snail will die.

Can snails repair their broken shell?

Many of us have heard of snail shell disease when we accidentally crush them while walking or cleaning a garden shed. If you have you must have wondered if this is the end spell for your unlucky garden friend.

The answer is yes. But the repair to their shells depends on the extent of their damage.

  • Body armour

Snails are born with their own shell but at first, the shell is soft and deformed. This soft initial shell soon hardens and grows with the snail in its adult life.

As the snail grows, it produces more soft-shell material that hardens to further develop its defensive shell.

If this shell breaks off enough, the snail will probably die. Although, snails can repair little cracks on their shells but if it is a large crack they might struggle to survive as their shell is responsible for their protection and also prevent them from drying out.

  • Human intervention

It has sometimes been known to use plaster and even ordinary adhesive tape to hold small broken shells together allowing the snails to fill in and seal the cracks.

How long do snails live in their shell?

Snail undergo a process known as estivation, they can hibernate for up to 3 years. They will stay inside their shells until food becomes more available or the weather is safe for them to come back out.

Do snails change shell?

Unlike hermits crabs, which change shells when they are very large, snails cannot change their shells or neither outgrow their shell. Snails develop and maintain their shells on their own and will lose valuable protection if they change the shell. They will not be able to repair or maintain a new shell as it will not be attached to its body.

Can they live without their shell?

A snail cannot live without its shell, the shell protecting it from predators and environmental conditions. If a snail is outside its shell it is because the shell has been destroyed, although some scientists theorize that parasites can make their way inside the shell and take the snail out. If a snail loses its shell it will soon die, no snails have been known to survive without their shell for more than a short period of time.
