The oldest part of a snail's shell is the center of the coil. When the snail grows, it grows outward
Yes! The shell of a snail is just like our spine. Its true- do not try and remove at anything- the snail would die a slow and painful death!

yes a baby snail will die if it's shell is chipped because a snail shell is very delicate and so is the snail.
It depend on what type of Snail it is because most snail produce their own shells, so the type of snail matters because some snails grow shells quicker than others and have a chance of surviving than the ones that can't grow their shell as quick.
No; the shell grows as part of the snail.
when a snail is born it has a shell, and its actual body is still growing in the shell.
The snail's shell will get writing on it. What do you think.
It is secreted by a portion of the snail body called the mantle.
Note: I copied this answer directly from: http://rochester.kidsoutandabout.com/main-columns/nature/snailshells.html Snails are hatched from eggs. When they hatch, they eat most of the shell, but a small part of it stays with them and that is the beginning of their shell. As the snail grows, so does its shell -- in a spiral shape. New shell is added at the opening of the shell. In the center of the spiral is the part of the shell that the snail began life with. The shell is made from several layers. The thin outer layer is made from an organic substance known as conchiolin. The thicker layer underneath is formed from three layers of crystalline calcium carbonate, similar to the chicken egg of which you may be more familiar. The color of the shell depends on the types of food the snail is eating and also the type of snail.
A snail's home is called a shell. The shell is a hard, protective outer layer that is made up of calcium carbonate. It serves as a home for the snail, providing protection from predators and environmental conditions. The shell also grows with the snail as it continues to develop.
if you mean the shell.... it is made of calcium, it grows with the snail and gains whorls (the spirals) ..............similar to a tree, the more spirals the older the snail.
